Mercury in Gold Processing ScienceDirect

01/01/2016· The main mercury-containing by-products from gold processing (and associated gas cleaning) are elemental mercury, mercury-containing carbon and in some cases, calomel. Mercury can be recovered from the carbon as elemental mercury. The behavior of mercury in a few specific areas of gold processing are discussed in more detail below. 2.1.

Amalgamation: Using Mercury to capture fine gold, retort

When clean gold comes into contact with mercury, the two substances mix to form a compound called amalgam an amalgam is simply an alloy of gold and mercury. The gold literally is dissolved into the mercury. This allows the collection of very small sized particles of gold. At the end of the operation the mercury and gold amalgam are collected after which the two are separated, and the mercury recycled. Now larger gold

The Mercury Problem in Artisanal and Small‐Scale Gold

To extract the gold from the crushed ore, liquid mercury is added directly to the trommel and mixed for several hours. Mercury is frequently used to capture the gold (rather than mercury‐free gravity separation techniques) in cases in which the gold grain is very fine. 20d, 21 In each trommel, it is common to add between 0.3 and 1 kg of mercury to 20 kg of crushed ore (Figure 2 B). 20d The

Amalgamation: Using Mercury to capture fine gold,

Mercury and free gold can be brought together in a number of ways, but to mix well, both the mercury and gold must be clean. Coatings, especially those which are oily in nature, prevent the two from mixing. In the old days, miners placed mercury in the riffles of sluices, dry washers, and similar devices to aid capture of fine gold. At the base of most of the old stamp mills was a plate
