gold flotation basics

The Introduction of Flotation Frothers | CNFREE

Elemental gold has a specific gravity of 19.3, and typical ore has a specific gravity of about 2.6. All gravity concentration devices create movement between the gold and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material. The prospector's gold pan is the most familiar gravity concentration device.

Basic Flotation Circuit Design

Mar 14, 2016· Flotation . Flotation method is more popular with large-scale miners although it is also used by artisanal miners. This is the perfect method for processing gold found in complex materials. The flotation method involves mixing your crushed ore with water and then you add frothing agents in a single floatation machine.

Archimedes' principle | Description & Facts | Britannica

A lower GSR can be tolerated if the flotation concentrate is amenable to direct cyanide leaching without the costly oxidation stage to release the gold from the sulphides. And on-site doré production avoids the off-site costs of transport and smelter charges, but usually with lower recovery (flotation recovery then oxidation-leach recovery) so ...

The gold can then be removed from the solution by electrowinning onto steel wool cathodes (refer 'Electrowinning and Smelting' module). As well as stripping the gold from the carbon, the elution process incorporates an acid wash stage, which removes inorganic foulants from the carbon. Foulants reduce the activity, and hence

Flotation frothers, also known as flotation foaming agent, is an essential flotation agent for froth flotation. The role of flotation frothers is mainly to produce a large amount of foam in the pulp, so that the available minerals are effectively enriched at the interface between air and water to create the conditions required for flotation process.The quality of flotation frothers directly ...
