This simple process flowsheet allows for Flotation Cyanidation Tailings in cases where ore bodies at depth have become more refractory and dotation ahead of cyanidation would call for major and expensive mill alterations, the sulphide minerals containing the undissolved precious metals can be recovered by flotation and shipped to the smelter. In some cases it is possible to make a selective separation of the auriferous sulphides wherein this is impossible if using flotation ahead of cyanidation.
In Flotation Cyanidation Tailings success depends on an effective and thorough wash of the cyanide tailing to minimize residual cyanide and lime in the flotation circuit. This refractory flowsheet is not recommended unless other more simple metallurgical methods fail.
