In plant production at the Telfer Gold and Copper flotation circuit, the use of PIONERA F-100 showed a recovery increase in gold of 5% and a positive effect on copper recovery by successfully depressing clay in the bulk flotation process. Positive laboratory results led to a plant trial with Pionera F-100 to determine its effect on gold/copper

Jan 01, 2005 Monothiophosphates are now used widely on copper–gold flotation plants. Mercaptobenzothiazole (MBT, Aeropromoter 404) is a fairly specialized collector (Finkelstein and Poling, 1977) and is the preferred collector for the flotation of gold and gold-carrying pyrite in acid circuits (O’Connor and Dunne, 1991). It is also recommended for

Nov 01, 2014 1. Introduction. Gold recovery is often well below copper recovery in copper–gold flotation plants (Zheng et al., 2010).As liberated and copper-associated gold is readily recovered by flotation, this recovery difference is often due to operating strategies that require rejection of gold-bearing iron sulphide gangue in order to maintain a saleable copper concentrate grade

Nov 01, 2019 The presence of gold in porphyry copper ores may require specific flotation strategies to ensure optimum recovery of both Au and Cu, which may differ according to gold mineralogy. Native gold generally floats well with the collectors used for the Cu sulphides (e.g., xanthates, dithiophosphates)

Jan 01, 2016 Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold recoveries

Jan 01, 2014 When low quality ores are processed and the gold price is decreased, many copper–gold plants have to close the CIL circuit and discharge flotation tailings directly to the tailing dams. To recover the gold from flotation tailings, it is important to understand limits of the CIL circuit and then develop an economically viable process

Jul 13, 2016 Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold.
