For each mole of copper extracted, the raffinate acidity is increased by one . mole. Extracting 4 g/L Cu completely, adds about 6.2 g/L H. 2. SO. 4. Extracting 20 g/L Cu adds 31 g/L acid. The higher the acidity, the more the extraction reaction is inhibited. Ultimately, with more acid, stripping takes place. A solution is to use

The effect of mill scale amount on copper extraction was added in the range of 0.5–5.0 g mill scale per 1 g chalcopyrite (Fig. 11). It was seen that the amount of mill scale was highly important in copper extraction from chalcopyrite concentrate. The copper extraction rates for 0.5 and 5.0 g mill scale were, respectively, 28% and 96% Cu.

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
