7.5. 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 ...

INTRODUCTION Gold-Copper ores, which require a Dllrumum of two metallurgical processes such as the production of a copper concentrate as a by-product to recover the copper content of the ore, and, the subsequent cyanide leaching of the flotation residues to recover the remaining associated gold, present, in most cases, processing challenges. Generally speaking, such operations face more ...

Commercial porphyry copper ores usually contain copper grades between 0.5% and 2%1. Minor amounts of gold are often present in these orebodies2. The concentration of gold in the majority of large-scale copper/gold ores is low, typically around 1-2 g/t3,4. Flotation is the principal method of pre-concentration for copper and gold5,6. Thus, porphyry copper ore concentrators are designed with the ...

Some copper sulfide ores also contain significant quantities of gold and silver. According to the mineral compositions, these ores can be sub-divided into three main groups including (a) copper-gold ore, (b) copper sulfide ore with moderate pyrite content and (c) massive sulfide copper ores. Copper porphyry ores are the most abundant copper ...

The plant was experiencing problems in the leach, adsorption, elution and electrowinning sections mainly as a result of the presence of copper in the ore. The changes made to the operating standards, the response of the circuit to these changes and the final Circuit layout and operating conditioning resulting in a 90% gold recovery are discussed.
