According to statistics, 93% of China's one-time energy supply comes from ore energy; 80% of industrial raw materials come from mineral products; 70% of agricultural production materials are related to mineral resources. The exploration and development of mineral resources not only laid the foundation for China's industrial development, but also made significant contributions to the sustainable development of the national economy and society.
However, in the face of huge demand for mineral resources from high-speed economic development, energy and important mineral resources are far from meeting the needs. Resource constraints on economic development have become increasingly prominent, and foreign dependence has risen sharply. In 2004, foreign dependence on oil was 45%. Ore 55%, copper 70%, alumina 45%, potassium salt 77%. The next 5 to 10 years will be a crucial period for China’s comprehensive construction of a well-off society. The degree of foreign dependence on energy and important mineral resources will further increase.
The prospects are very promising. The White Paper of China's Mineral Resources Policy states that China's exploration and development potential for mineral resources is still quite large. Since the 1980s, an abnormality of 72,000 mineralizations has been discovered, an abnormality of 25,000 inspections and 217 ore deposits have been discovered. The remaining unchecked anomalies have good prospecting prospects. There are a large number of resources in the western and central and eastern regions of the existing mines and in the deep waters, and in the jurisdictional sea areas in China, to be further identified. Chen Zhouqi said that these are the directions for exploration and development of mineral resources in China in the future. Studies have shown that the provenance of oil resources is low, and the proven oil geological reserves on land only account for one-fifth of all resources, and the provenance of offshore waters is even lower. The average level of identification of important metal mineral resources is 35%. Compared with the identification of resource reserves, among the resources to be identified, iron or aluminum and other minerals still have double the prospecting potential. Copper, manganese, nickel, tin, etc. About 2 times the potential; the potential of lead, zinc, gold and other minerals is even greater, about 3 times. In 2005, 169 large and medium-sized mineral deposits were newly discovered in China’s geological surveys and mineral resources exploration, including 40 energy minerals, 3 ferrous metal minerals, 44 non-ferrous metal minerals, 11 precious metal minerals, and 7 metallurgical auxiliary raw material minerals. There are 5 raw material minerals, 52 non-metallic minerals of building materials and 7 water and gas minerals.
In the adjustment of economic growth, China's mining economy is booming. The output of mineral products grew rapidly and the consumption of mineral products continued to rise. In 2005, raw coal production reached 2.19 billion tons, an increase of 11.7% over the previous year; crude oil was 181 million tons, an increase of 3.4%; natural gas production was 49.95 billion cubic meters, an increase of 22.4%; iron ore production was 421 million tons, a year-on-year increase of 35.8 %; 10 kinds of non-ferrous metals were 16.35 million tons, a year-on-year increase of 14.3%; gold production was 224.05 tons, a year-on-year increase of 5.5%. With the rapid economic development, in recent years, the annual consumption of mineral products ranks among the top in the world. In 1990, the consumption of crude oil was 115 million tons, and by 2005 it had increased to 317 million tons. In 1990, the coal consumption was 1.026 billion tons. In 2005, the coal consumption was 2.16 billion tons, ranking first in the world. Driven by strong demand, trade volume of mineral products in the international market has increased significantly. In 2005, the total trade volume of mineral products exceeded US$300 billion. The total import and export volume of mineral products exceeded 22% of the total import and export volume of all commodities in the country. Many mineral products are in short supply, and the prices of energy precious metals and various major non-ferrous metal mineral products have risen sharply and remain high. Many mineral products prices have hit record highs for many years. The mining industry has become a highly profitable industry.
National Policy Encouragement According to Chen Zhouqi, in order to ease the resource bottlenecks of economic and social development, the state has adopted a series of policies and policies that have brought unprecedented development opportunities to the development of the mining industry. The State encourages domestic enterprises and other economic organizations to explore and develop mineral resources in the country in accordance with the relevant laws, regulations and policies of the country, expand the mining industry's opening up to improve the mining investment environment, and create good foreign investment and foreign cooperation for domestic mining companies. condition.
The state has formulated many incentive policies in the aspects of investment system, investment industry guidance catalogue, taxation, finance, environmental protection, foreign exchange, customs, mining land, and exploration and development of western mineral resources. Even after the exploration right holders have invested in mining sites with mining value, they can obtain mining rights in accordance with the law, and allow exploration costs to be included in deferred assets. Detailed amortization is also made during the phase of mining in stages. For all types of investment, creating a fair, orderly market environment and positive policy environment.
A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the material gets smaller as it moves down through the wear liner as the opening in the cavity gets tighter. The crushed material is discharged at the bottom of the machine after they pass through the cavity.
Mineral resource development will become a highly profitable industry
At the 4th China Investment Environment Forum held in Hangzhou recently, Chen Zhouqi, deputy chairman of the Population Resources and Environment Committee of the National Committee of the Chinese People's Political Consultative Conference, believes that exploration and development of mineral resources is an excellent investment area for the current and future periods.
