· Abstract. The aim of this paper is to reflect on efforts made worldwide to construct processing centres where artisanal miners can visit to have gold extracted from ore “free” or for a nominal fee. These centres use inefficient grinding and amalgamation processes to extract less than 30% of the gold to give back to the miners.

· Although most of the gold produced each year originates from primary gold ores or concentrates, a significant amount of gold is recovered as by-product from the production of base metals and from the recycling of scrap. From a current gold world production of approximately 2,600 tonnes, about 10% is recovered as a by-product (

An overall equation for this series of steps is: 2CuFeS2 + 2SiO2 + 4O2 → Cu2S + 2FeSiO3 + 3SO2 (1) The copper (I) sulfide produced is converted to copper with a final blast of air. Cu2S +O2 → 2Cu + SO2 (2) The end product of this is called blister copper-a porous brittle form of copper, about 98-99.5% pure.
