Quercus is a platinum element. Platinum metals almost completely into elemental state, that highly dispersed in various ores, such as the original platinum mines, copper-nickel sulfide ore, a magnetic iron ore. Platinum group elements co-exist almost without exception, forming a natural alloy. In p
The separation of gold and silver is carried out by the nitric acid method. The basic principle is to react silver and other base metals with nitric acid to form soluble nitrates. Gold is not reacted with nitric acid and deposited on the bottom of the reaction vessel to achieve the purpose of gold a

I. Introduction In 2007, global aluminum 's total performance consumption was 53.000kt. Among them, recycled aluminum smelted from recycled aluminum is 30.2% of the total consumption, which is about 16.000 kt. Recycling of used worldwide each year, about 32% aluminum modified aluminum alloy fl
Deposit account after the contact of magmatic skarn copper-containing magnetic iron deposit exploration type is a three to four. The mine's No. III ore body and the No. IV ore body are deep underground. The No. III ore body is about 370m long, with an average thickness of about 40m, a maximum t
At present, China vein of gold ore and gold sulfide mostly using the flotation process sorting, in the flotation process, adding a large number of flotation reagents. These agents are mainly butyl xanthate, turpentine, individual gold plant using ADDP, and using kerosene as collector. The flotation
Overview of China's cobalt ore resources and suggestions for improving the supply capacity of cobalt mines in China I. Overview of China's cobalt resources Cobalt is an important strategic metal, due to its excellent physical, chemical and mechanical properties, are widely used in aviatio
Of gold heap leaching process is inherently qualitative, technological factors influence the production process of gold leaching reactor are: solution spray leaching properties (cyanide concentration, oxygen content and pH value, etc.), liquid leaching Strength, ore properties (mineralization prope
