Gold Cyanidation - groundtruthtrekking

Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

The ore blend is reclaimed from the stockpile and fed to two parallel mineral sizers, a type of crusher designed to handle the softer ores that are found at the Sadiola Gold Mine. The ore passes to surge bins located ahead of the two SAG mills. A single regrind mill is incorporated, serving both circuits, to further grind the coarse fraction contained in the output from the SAG .

Gold processing - Mining and concentrating | Britannica

Amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury, by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel, or by grinding the ore in a ball, rod, or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury.

Mill (grinding) - Wikipedia

A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by ...
