Bulk mineral resources of iron ores, copper ores, bauxite, lead ores, zinc ores and potassium salt play a pivotal role on the world＇s and China＇s economic development. This study analyzed and predicted their resources base and potential, development and utilization and their world＇s and China＇s supply and demand situation in the future 20 years. The supply and demand of these six bulk mineral products are generally balanced, with a slight surplus, which will guarantee the stability of the international mineral commodity market supply. The six mineral resources （especially iron ores and copper ores） are abundant and have a great potential, and their development and utilization scale will gradually increase. Till the end of 2014, the reserve- production ratio of iron, copper, bauxite, lead, zinc ores and potassium salt was 95 years, 42 years, 100 years, 17 years, 37 years and 170 years, respectively. Except lead ores, the other five types all have reserve-production ratio exceeding 20 years, indicative of a high resources guarantee degree. If the utilization of recycled metals is counted in, the supply of the world＇s six mineral products will exceed the demand in the future twenty years. In 2015-2035, the supply of iron ores, refined copper, primary aluminum, refined lead, zinc and potassium salt will exceed their demand by 0.4-0.7 billion tons （Gt）, 5.0-6.0 million tons （Mt）, 1.1-8.9 Mt, 1.0-2.0 Mt, 1.2-2.0 Mt and 4.8-5.6 Mt, respectively. It is predicted that there is no problem with the supply side of bulk mineral products such as iron ores, but local or structural shortage may occur because of geopolitics, monopoly control, resources nationalism and trade friction. Affected by China＇s compressed industrialized development model, the demand of iron ores （crude steel）, potassium salt, refined lead, refined copper, bauxite （primary aluminum） and zinc will gradually reach their peak in advance. The demand peak of iron ores （crude steel） will reach around 2015, 2016 for potassium salt, 2020 for refined lead, 2021 for bauxite （primary aluminum）, 2022 for refined copper and 2023 for zinc. China＇s demand for iron ores （crude steel）, bauxite （primary aluminum） and zinc in the future 20 years will decline among the world＇s demand, while that for refined copper, refined lead and potassium salt will slightly increase. The demand for bulk mineral products still remains high. In 2015-2035, China＇s accumulative demand for iron ores （crude steel） will be 20.313 Gt （13.429 Gt）, 0.304 Gt for refined copper, 2.466 Gt （0.616 Gt） of bauxite （primary aluminum）, 0.102 Gt of refined lead, 0.138 Gt of zinc and 0.157 Gt of potassium salt, and they account for the world＇s YOY （YOY） accumulative demand of 35.17%, 51.09%, 48.47%, 46.62%, 43.95% and 21.84%, respectively. This proportion is 49.40%, 102.52%, 87.44%, 105.65%, 93.62% and 106.49% of that in 2014, respectively. From the supply side of China＇s bulk mineral resources, it is forecasted that the accumulative supply of primary （mine） mineral products in 2015-2035 is 4.046 Gt of iron ores, 0.591 Gt of copper, 1.129 Gt of bauxite, 63.661 Mt of （mine） lead, 0.109 Gt of （mine） zinc and 0.128 Gt of potassium salt, which accounts for 8.82%, 13.92%, 26.67%, 47.09%, 33.04% and 15.56% of the world＇s predicted YOY production, respectively. With the rapid increase in the smelting capacity of iron and steel and alumina, the rate of capacity utilization for crude steel, refined copper, alumina, primary aluminum and refined lead in 2014 was 72.13%, 83.63%, 74.45%, 70.76% and 72.22%, respectively. During 2000-2014, the rate of capacity utilization for China＇s crude steel and refined copper showed a generally fluctuating decrease, which leads to an insufficient supply of primary mineral products. It is forecasted that the supply insufficiency of iron ores in 2015-2035 is 17.44 Gt, 0.245 Gt of copper in copper concentrates, 1.337 Gt of bauxite, 38.44 Mt of lead in lead concentrates and 29.19 Mt of zinc in zinc concentrates. China has gradually raised the utilization of recycled metals, which has mitigated the insufficient supply of primary metal products to some extent. It is forecasted that in 2015-2035 the accumulative utilization amount of steel scrap （iron ores） is 3.27 Gt （5.08 Gt）, 70.312 Mt of recycled copper, 0.2 Gt of recycled aluminum, 48 Mt of recycled lead and 7.7 Mt of recycled zinc. The analysis on the supply and demand situation of China＇s bulk mineral resources in 2015-2035 suggests that the supply-demand contradiction for these six types of mineral products will decrease, indicative of a generally declining external dependency. If the use of recycled metal amount is counted in, the external dependency of China＇s iron, copper, bauxite, lead, zinc and potassium salt will be 79%, 65%, 26%, 8%, 16% and 18% in 2014, respectively. It is predicted that this external dependency will decrease to 62%, 64%, 20%, -0.93%, 16% and 14% in 2020, respectively, showing an overall decreasing trend. We propose the following suggestions correspondingly. （1） The demand peak of China＇s crude steel and potassium salt will reach during 2015-2023 in succession. Mining transformation should be planned and deployed in advance to deal with the arrival of this demand peak. （2） The supply-demand contradiction of China＇s bulk mineral resources will mitigate in the future 20 years, and the external dependency will decrease accordingly. It is suggested to adjust the mineral resources management policies according to different minerals and regions, and regulate the exploration and development activities. （3） China should further establish and improve the forced mechanism of resolving the smelting overcapacity of steel, refined copper, primary aluminum, lead and zinc to really achieve the goal of ＂reducing excess production capacity＂. （4） In accordance with the national strategic deployment of ＂One Belt One Road＂, China should encourage the excess capacity of steel, copper, alumina and primary aluminum enterprises to transfer to those countries or areas with abundant resources, high energy matching degree and relatively excellent infrastructure. Based on the national conditions, mining condition and geopolitics of the resources countries, we will gradually build steel, copper, aluminum and lead-zinc smelting bases, and potash processing and production bases, which will promote the excess capacity to transfer to the overseas orderly. （5） It is proposed to strengthen the planning and management of renewable resources recycling and to construct industrial base of renewable metal recycling. （6） China should promote the comprehensive development and utilization of paragenetic and associated mineral species to further improve the comprehensive utilization of bulk mineral resources. 展开更多

Generally, the sequence decision of the development and utilization of Chinese mineral resources is based on national and provincial overall plan of the mineral resources. Such plan usually cannot reflect the relative size of the suitability of the development and utilization of mineral resources. To solve the problem, the paper has selected the gift condition, the market condition, the technological condition,socio-economic condition and environmental condition as the starting-points to analyze the influential factors of the priority-sequence of mineral resources' development and utilization. The above 5 conditions are further specified into 9 evaluative indicators to establish an evaluation indicator system. At last,we propose a decision model of the priority sequence based on grey relational analysis method, and figure out the observation objects by the suitability index of development. Finally, the mineral resources of a certain province in China were analyzed as an example. The calculation results indicate that silver(2.0057), coal(1.9955), zinc(1.9442), cement limestone(1.9077), solvent limestone(1.5624) and other minerals in the province are suitable for development and utilization. 展开更多

Fossil energy is also consumed in large quantities. The main reason for this phenomenon is that human beings have caused certain damage to the environment in pursuit of economic benefits. Under the realistic pressure of environmental pollution and energy shortage; All over the world are actively developing new energy products around the concept of sustainable development and low-carbon environmental protection, so as to reduce the consumption of all kinds of energy and exhaust emissions. But up to now, there is still no new energy form that can replace the commonly used fossil energy. At present, the energy forms such as wind power generation and solar power generation, whose installed capacity is rising rapidly, can only be used as a supplementary form of energy, because a lot of resources need to be dissipated in the production process of wind power generation and solar power generation equipment, especially the conversion rate of solar power generation equipment is poor. However, biomass power generation is a completely different form from the current wind power and solar power generation, which belongs to the utilization of renewable resources. However, the consideration of raw material supply and other issues in the development of biomass projects is limited, and it cannot replace traditional energy sources. The development of energy-saving products and new energy has become an important way to effectively develop low-carbon economy. However, the development and innovation of new energy technologies need a large amount of research funds as support, such as increasing the running time of wind power generation equipment, increasing the conversion rate of solar power generation equipment, including the disposal methods at the later stage of the equipment, etc., all of which need the support of government funds before we can master the core technologies, but the huge research expenses are also a great pressure on the government. Therefore, we should do a good job in the development planning of new energy, gradually improve the development space of new energy and effectively control energy conservation and emission reduction, such as rationally planning the development space of wind power generation and solar power generation, improving the equipment conversion rate and bringing the project into the best condition. Paying attention to the promotion of new energy vehicles, increasing the proportion of new energy vehicles to a favorable range in the future, and reasonably reducing vehicle exhaust emissions are also important indicators to reduce emissions. This paper discusses the development and utilization of new energy under the background of low-carbon economy, hoping to bring some reference suggestions to people in the industry. 展开更多

Exploring the geological genesis of selenium(Se)in Se-rich soil of the Hetao Plain,a major grain production base of corn,wheat,potato,sunflower and zucchini in northern China,is vital for the rational development of Se-rich land resources and the environmental geochemical assessment.In this study,element geochemical characterization,geospatial analysis and mathematical statistics were employed to investigate the factors influencing the spatial distribution of soil Se in the Hetao Plain,focusing on the differences in soil chemical weathering intensity,rare earth elements distribution pattern and soil sedimentary sequence characteristics between the study area and typical surrounding parent materials.The results indicated that the soil Se content in the study area ranged from 0.07 mg/kg to 0.72 mg/kg,with an average value of 0.24 mg/kg,which was higher than the regional background values.Moreover,this suggested that local Se enrichment occurred in the soil of study area,and that the Se distribution was restricted by factors including soil clay minerals,constant elements and soil organic matter(SOM)contents.The characteristics of soil parent material in the study area differed significantly from those of the piedmont diluvial parent material,whereas were similar to those of the Yellow River floodplain and lacustrine parent materials,revealing that the soil parent material in the study area mainly came from the water system transportation.Through combining the characteristics of soil sedimentary sequences in the study area with the location of the Yellow River ancient channel,it is suggested that the origin of high Se soil in the central and northern belt zone of the study area is associated with the Yellow River ancient channel,where the enrichment pattern is“channel sedimentary type”.In addition,the development and utilization potential of Se-rich cultivated land was explored based on the biological effects of Se.It was concluded that the Se content of crops(corn,sunflower and zucchini)in the study area was higher than that of similar crops in China,that crop species and soil Se content were the dominant influencing factors of crop Se content in the study area,and that the crops growing in Se-rich areas had higher Se enrichment rate than those growing in non-Se-rich areas.This exhibited a high development and utilization potential of the investigated cultivated land for Se-rich crop production. 展开更多

Analysis of water supplies and demand over the past 50 years in the Gavkhuni River Basin（GRB） indicate that despite large investments in water resources development the basin remains just as vulnerable to drought as it always has been. During the period of analysis two transbasin diversions and a storage reservoir have been constructed which have more or less doubled the annual supply to water to the basin. But with each water resource development extractive capacity for irrigation, urban and industrial use has increased by the same amount, so that all new water is allocated as soon as it is available. The most recent developments, since 1980, have actually increased vulnerability to drought because extractive capacity is greater than average flow into the basin. Whenever demand exceeds supply all water is extracted from the basin and the tail end dries up. During the past 50 years flows into the salt pan at the downstream end of the basin have been negligible for more than half the time. Prospects for the future are bleak because once the current phase of water resources development is completed no further water supplies are likely, but demand continues to rise at a steady rate. Ultimately agriculture will have to concede water to urban, industrial and environmental demands. 展开更多
