Low-sulfide primary ores. Depending on the size, gold is usually extracted from low-sulfide primary ores using a one- or two-stage gravity-flotation scheme in combination with amalgamation or cyanidation. If the ore contains sufficiently large gold, gravity enrichment is used after the first stage of crushing. This scheme, using gravity ...
