The first stage is a conventional copper flotation with depression of pyrite to produce a gold-copper concentrate. Tails from the first stage are refloated to produce a pyrite-gold concentrate which is leached with cyanide in a conventional CIL circuit to recover the remaining gold as dor .
Mar 18, 2016 The EXAMPLE Gold Mill is designed to process 500 tonnes per day of ore. The flowsheets are conventional and consist of two stages of crushing, single stage ball mill grinding, cyanidation and a Merrill-Crowe precipitation circuit for gold and silver recovery. In addition to the cyanide circuit, gold leach residue is treated in a flotation stage to recover un-leached silver (Argentite) minerals.
• Gold/Silver base metal concentrate deportment Smelters typically pay 95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60% -70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.
Feb 01, 2011 At Mill 5, 15,000 t/d are processed with the plant achieving 94% availability and 70% overall gold recovery. Some 600 t/d of concentrate is produced.
