Chalcocite (/ ˈ k æ l k ə ˌ s aɪ t /), copper(I) sulfide (Cu 2 S), is an important copper ore is opaque and dark gray to black, with a metallic has a hardness of –3 on the Mohs is a sulfide with a monoclinic crystal system.. The term chalcocite comes from the alteration of the obsolete name chalcosine, from the Greek khalkos, meaning "copper".
· 【Principle】Gold heap leaching refers to pile up lowgrade gold ore or flotation tailings on the bottom mat material, and then spray it through the NaCN solution to dissolve the gold in the ore to form a goldcontaining pregant liquid and finally refine to recover gold. 【Process】 1.

Stratigraphy geologic history. The oldest rocks in South Sudan are Precambrian gneiss, metasediments and basic volcanics that form the igneous and metamorphic basement rock that underlies the country and is exposed as 40 percent of its Precambrian rocks may be well over two billion years old. However, in most cases they were reactivated and altered in .
· The stocks are porphyritic in texture, locally brecciated, and characterized by development of a carbonate, anhydrite, and quartz stockwork system. Structural observations, detailed petrography, and sulfide geochemistry reveal that copper and gold in the stockworks and surrounding altered rocks cannot be associated with the same mineralizing event.
center of the system. The copper ores are characterized by the following sulfidebearing minerals: chalcopyrite, bornite and molybdenite (minor) with minor to moderate amounts of pyrite. These ore bodies are very large, generally containing from 100 million to several billion tons of copper ore with a copper content of % to %.
· 3. China – million tonnes. China mined an estimated million tonnes of copper in 2020, placing it third on the list of the world's largest copper producing countries. The Chinese economy is the biggest global consumer of the metal, and imports large volumes to supplement its own domestic production. Jiangxi Copper is one of the ...
· A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel ...

· Sulfide Copper Ores . Virtually all sulfidetype copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.
