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 …

Some other key drivers in flowsheet selection at the hashing stage are: Supergene weathering. This is common in tropical environments (e.g. West Africa) and typically oxidises gold-bearing sulphides down to 50-100m, transforming commonly refractory gold in sulphides to 'free-milling' gold, behaving in a similar fashion to gold …

Leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. In extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, ...
Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores.

The gold contained in the ore occurs at an average of. 17 opt (ounces per ton of ore). The gold is within the sulfide mineral matrix, which is not exposed (and therefore can not be dissolved by) a cyanide leach solution. Also the ore contains carbonaceous matter which absorbs gold in the conventional leaching process.
