1/1/2014· This plant currently operates at 21 Mtpa ore throughput and recovers gold by gravity separation, copper flotation and CIL. The feed grade is about 0.18% Cu and 0.7 g/t Au. Gravity gold concentrators are utilised within primary grinding circuits to recover free gold, producing gold doré.
Implementation of regrindflotation pre treatment of the CIL feed in a . 1. Introduction. Gold recovery is often well below copper recovery in coppergold 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 ...
1/1/2016· Flotation of CopperGold 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 . This combination gives satisfactory results in respect of copper concentrate grade and copper and gold recoveries.
13/7/2016· GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.
grade copper gold ores from open pit and underground sources in two parallel processing trains. The copper flotation circuits upgrade copper content by a factor of 80 160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed (remaining gold
