Leaching solutions (or lixiviants) used in heap leach mining are either highly alkaline such as sodium cyanide, or highly acidic such as sulphuric acid. To ensure uniform distribution of the lixiviant to the ore heap and to minimize evaporation, drip irrigation systems are the preferred distribution method.

Heap leaching is not that popular in South Africa because it is more applicable to shallow opencast mining, and South African gold mines are mostly underground operations. The method is, however, being used on a large scale in the copper mines of South America and, according to Bundo, it will be used more and more on the African continent in future.

The invention relates to a method for the sulphate-based leaching of metal sulphide minerals, such as chalcopyrite, CuFeS 2 , containing ore in atmospheric conditions. It is beneficial for the leaching of metal sulphides that the sulphide to be leached is treated before leaching or at the beginning of leaching with a sulphide salt that is more noble than the sulphide or the components it includes.

Copper Leaching Method

This 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.
