Heap Leaching Copper By Sulfuric Acid alanglover

The method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores (as high as 1,000 kg of acid per tonne of ore, but 500 kg is more common.)

Benefits of Agglomeration in an SX-EW Process for Copper

The copper solution resulting from heap leaching still contains impurities that must be removed before a pure copper product can be produced. For this, an extractant is needed. The process of extracting the copper from the solvent is typically carried out in mixer-settlers which use different types of extractants to purify the copper in two stages.
