A method for extracting copper from a mineral feed containing copper sulphide mineral (1), which involves crushing and blending the feed (2, 6, 10) followed by leaching of the feed in an antoclave (20). The conditions in the autoclave are controlled so that the presence of oxygen at superatmospheric oxygen pressure maintains the ratio of ferrous to ferric ions at a level so as …

The patented intec copper process was developed for the recovery at LME Grade A purity from sulfide concentrates. Essentially, the intec copper process consists of the three sequential circuits: leaching, purification and electrowinning. A simple flow diagram for the intec copper process is shown in Fig. 6. 2.2.2.1.2. The Cuprex Process

Sulfide ores undergo a five-step process: 1) the ore is crushed into a fine sand to loosen the copper minerals; 2) it is froth floated, where the sand is mixed with water and chemicals to make the copper particles water repellent; 3) air is passed through the mixture, allowing the copper minerals to attach to bubbles …

Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as "collect early, loss early" and "more crushing and less grinding".

Processing Copper Sulfide Ore . Sulfide ores are generally processed using pyrometallurgy. Mining considerations: Sulfide ore is often less abundant. Pyrometallurgy process is more expensive. Sulfide ore is often a higher-grade ore (contains more copper) Ultimately more copper can be extracted from sulfide ore deposits

Inside the ball mill, the crushed copper ore will grind the ore to about 0.2 mm with 3inch steel balls. 3. The copper ore slurry is pumped to the agitation tank. This copper ore slurry is finally pumped to the flotation machine with the fine sulfide ore (~0.074 mm) going to froth flotation cells for recovery of copper. Read More

The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper. This is cast into slab-like anodes. Principal impurities are iron and precious metals (gold and silver). The anodes are electrolytically refined in cells sketched in Fig. 8.
