Shandong Province gold mine. Gold mining in the province can be traced back at least the Northern Song Dynasty era. Has become one of the important gold production base. Gold's GDP, output, profits, foreign exchange and gold reserves, ranking first in the country. National investment in new and renovated homes burnt, Metro, Yinan, Rushan four medium-sized mines, gold production in Shandong province shows good prospects. Now, the focus of the country's 10 gold mines in Shandong Province accounted for 5, including the famous gold and Island Gold Zhaoyuan. In recent years, the masses of gold mining enterprise in Shandong Province has developed rapidly Cinder machine, there are gold mining point of Yantai, Linyi, and other regions of 250 multiple. Gold is mainly concentrated in Shandong Province Shandong Peninsula in Zhaoyuan - YeXian area, producing more concentrated gold mine slag machine, easy to large-scale mining. Second, the mining method based classification process mining method we use a lot of class, in order to facilitate the use of copper slag machine, it is necessary to classify. The method also has a variety of classification fluorite ore slag machine, but before the general classification method is based on different ways to pressure management to classification. Because ground pressure management method is based on the physical and mechanical properties of rock and minerals as unfounded, while mining methods and conditions, composition closely related elements, such as the recovery process, and ultimately will affect the safety, efficiency and economic effects of mining method . Lead-zinc 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.
