Grinding fineness is an important factor affecting the beneficiation index of copper sulfide ore.If the grinding particle size is too fine, the ore is easy to be over-crushed, which affects the separation process and increases the grinding cost.If the grinding particle size is too coarse, the copper minerals will not be effectively dissociated, which

Copper Mining and Extraction Sulfide Ores

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore

Ore column leaching with thermophiles: I, copper sulfide

2012-10-1  1. Introduction. The discovery of mineral sulfide-oxidising thermophiles in a large scale simulation of copper ore heap leaching (Murr and Brierley, 1978) increased interest in their potential application in acidic ore dump and heap leaching.Two morphologically-distinct, rod-shaped, moderately thermophilic bacteria described at that time came from the large scale simulation (Brierley and

What is Sulfide Mining? Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to

What is the sulphide ore of copper? askinglot

Copper is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting. The obtained metal is then purified by electrolytic refining.

Extraction of copper from complex carbonaceous sulfide

1. Introduction. The complex carbonaceous sulfide ore is categorized under the sediment-hosted stratiform copper deposits which account for about 20–25% of the world's copper production and reserves (Hitzman et al., 2005, Misra, 2000).Carbonaceous sulfide ores host polymetallic minerals characterized by carbonates (dolomite, calcite, magnesite, etc.) and carbonaceous materials (inorganic

Parantar METE 157N: HYDROMETALLURGY LABORTORY ABSTRACT Sulphide ores of copper are insoluble in dilute sulphuric acid leaching solutions, but a very high extraction can be obtained if the copper ore is in the oxidized condition.

Copper Sulfide an overview ScienceDirect Topics

Copper sulfide minerals require the use of acid and an oxidizing agent to break the mineral lattice and release Cu2+ into solution ( Sherrit, Pavlides, & Weekes, 2005 ). Elemental copper found in nature can be leached by either oxygen or ferric ion: (15.6a) Metallic copper: Cu + 0.5 O 2 + H 2 SO 4 → Cu 2 + + SO 4 2 − + H 2 O.
