Copper Mining and Extraction Sulfide Ores
Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid.
A Review on Novel Techniques for Chalcopyrite Ore Processing
At present, there are basically two main methods employed worldwide in order to process chalcopyrite for metal production. The most important one is the conventional - pyrometallurgy method: comprised numerous types of shaft and flash technologies, which consists of crushing, grinding, flotation, smelting, refining and electro-refining.
Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Chalcocite - Wikipedia
Chalcocite (UK: / ˈ k æ l k ə ˌ s aɪ t /), copper(I) sulfide (Cu 2 S), is an important copper ore mineral. It is opaque and dark-gray to black with a metallic luster.It has a hardness of 2 1 ⁄ 2 - 3 on the Mohs scale.It is a sulfide with an orthorhombic crystal system.. The term chalcocite comes from the alteration of the obsolete name chalcosine, from the Greek khalkos, meaning copper.
CHALCOCITE (Copper Sulfide)
Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur.

1. Introduction. Bioleaching of copper, focused on the dissolution of reactive or secondary copper sulphides by bacterial action, is now a common processing method for the recovery of copper at a wide range of locations (Watling, 2006).In the case of bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S), dissolution occurs either through ferric iron (Fe 3+) oxidation (eqs.
Chalcocite - an overview | ScienceDirect Topics
The separation of chalcocite (Cu 2 S) and heazlewoodite (Ni 3 S 2) from high nickel matte can be achieved by maintaining the proper pH and pulp potential while using xanthates as collectors.The flotation recovery of Cu 2 S and Ni 3 S 2 has been studied by adjusting the oxidation–reduction potential of the flotation pulp with (NH 4) 2 S 2 O 8 and KMnO 4.The recovery of Ni 3 S 2 is almost zero ...
