Nuggets taken from streams and free gold retrieved by panning, sluicing and dredging could go directly to the smelter. Before the gold found in the ore taken from hard rock mines became gold ingots or gold coins, it went several complicated rounds of chemical and mechanical processing. Men and machines at mills worked together to pulverize and …

The alluvial tin ore processing method is similar to placer/soil gold processing. Generally, the gravity separation method is used. It is the most economical and effective method for processing alluvial tin, as the specific gravity difference between tin ore and barren material is very large, and this method is environmentally friendly and …

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.
