The value of iron ore mined by GEOLOGY (burial depth, geological conditions) and the nature of the ore (type of iron ore, magnetic iron content, useful content dissemination size characteristics and other factors) affect the characteristics of the different, quite different. 20% grade magnetite ore resources now even good slag machine, mine is good, if it is not necessary to other types of iron ore mining. Cheng Li of China 50 years ago, launched a large-scale mineral geological survey work, has made great achievements, has been the implementation of mining operations have 168 kinds of minerals found proof Cinder machine, there are a number of proven there are 153 kinds of mineral coal Pa Slag, which eight kinds of energy minerals, 54 kinds of metallic minerals, 88 kinds of non-metallic minerals, three kinds of mineral water and gas, the potential value of proved reserves after the United States and the former Soviet Union, the new slag machine, ranking third in the world, is the world's most abundant mineral resources, mineral complete one of the few countries supporting. 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. Large slope slag machine _ Xinhua machinery (certified) _ Cinder machine provided by Gongyi City Xinhua Machinery Factory. Gongyi City Xinhua Machinery Factory (www.gyxinhua.com) is a leader in Zhengzhou, handling equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Xinhua leader in mechanical staff warmly welcome all inquiries negotiations to create a better future, Xinhua machinery.
