Pulp Density - an overview | ScienceDirect Topics

Eoin H. Macdonald, in Handbook of Gold Exploration and Evaluation, 2007. Control. Solids feed rates and pulp density must be closely monitored and controlled for the efficient operation of plant recovery units. In jigging practice for example, the flow of water and solids across a jig is generally optimal at around 25% solids by weight. At reduced pulp densities the flow of top water increases .

Gold Extraction & Recovery Processes

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching process.

Stamp mill - Wikipedia

Stamp mill - Wikipedia

A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.

The amalgamation process is an old gold extraction process, simple and economical, suitable for the recovery of coarse-grained monomer gold, but it has pollution to the environment and is was gradually replaced by gravity separation, flotation and cyanidation process. The cyanidation gold extraction process includes cyanide leaching, cyanide .

Extraction of Gold

Extraction of Gold

The ore is reduced to a fine state of division and amalgamated simultaneously in a stamp-mill, the solid gold-amalgam separated from the liquid mercury by filtration through leather under pressure, and the mercury distilled. Complete extraction of the gold by amalgamation is impossible, a part remaining in the mud of the stamp- mills.
