Copper FlotationMineral Processing & Metallurgy

A Copper Flotation Flowsheet Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. . thus some form of regrinding is necessary on the rougher flotation copper concentrate. It is not unusual to grind the rougher flotation .

Pyrite-Gold Recovery in Copper Rougher Flotation Tailings

gold flotation behaviour in different test conditions (Cu rougher feed aerated and non-aerated) using SIBX/XD5002 as collector, p80=38 µm. However, when the copper rougher tails (Test 1, Test 2 and Test 3) were reground, only 25% of the total gold lost was recovered in Test 1. Test 2 showed the highest gold recovery
