A total recovery of more than 97% of thegold and silveris made by flotation, while the combinedflotation-cyanidation processgives an overall extraction of 95%. The installation is much more compact and its capital cost far less than one embodying fine grinding and cyaniding of the whole tonnage, and it can be run with lower operating, maintenance, and depreciation costs.

GOLD AND SILVER PROCESSING. EFD has a number of industry-leadingflotation productsforprocessing gold. This includes the HydroFloat, a state-of-the artflotation unitthat uses fluidization to selectivelyfloatcoarse and high SGgold particlesthat cannot normally be concentrated usingflotation. We also have a range of air sparging product s, including the SlamJet™ and the CavTube™ which greatly improve the kinetics of cyanide leaching byproducing…

The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes:oresin which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, thebasemetal minerals, if present, being of little or no value.

Gold flotation. The FrothFlotationMethod is means separating minerals according to their different physical and chemical properties. According to classification, the flotability ofgold and silverminerals is included in the first category of natural and non-ferrous heavy metal sulfides, characterized by low surface wettability and easyflotation, which can beflotationby xanthate collectors.
