Gold in the earth's crust abundance already low, and have an affinity to sulfur, copper pro-sexual nature, pro-ferrous melting point and so on. To form a slag deposits in industrial machines, gold enrichment thousandfold want to form a large ore-grade ore, gold will have enriched thousands, hundreds of thousands of times, or even higher. Generally believed that huge gold generally through a long geological time, through a variety of sources, tectonic evolution and mineralization superimposed times it may be forming. 50 Years of New China Cheng Li Cinder machine wholesale prices, to carry out a large-scale mineral geological survey work, has made great achievements in the implementation of mining operations now have 168 kinds of minerals found Cinder machine manufacturers, there are a number of proven mineral 153 kinds, including eight kinds of energy minerals, 54 kinds of metallic minerals, 88 kinds of non-metallic minerals, water and gas mineral three kinds, the potential value of proved reserves after the United States and the former Soviet Union, ranking third in the world, is the world's mineral resources The most abundant minerals fully supporting one of the few countries. Energy Minerals Energy and Minerals is an important part of China's mineral resources. Coal, oil, natural gas is about 93% and 95% in the world and China's primary energy consumption, respectively. Because fossil fuels in primary energy consumption in a dominant position, and thus on the economic and social development has a special strategic importance.
