Sulfidization is used in froth flotation circuits to recover oxide materials that don’t respond to sulfide copper collectors.
Make An EnquiryOxide minerals generally don’t respond well to traditional methods of concentration using known sulfide copper collectors. Their recovery in a froth flotation circuit requires special treatment.
The traditional method involves sulfidization, using sodium sulfide (Na2S), sodium hydrosulfide (NaSH) or ammonium sulfide ((NH4)2S), followed by flotation using Xanthate or other sulfide collectors, which are usually stage-added for both efficacy and control.

Agnico Eagle Fosterville Gold Mine (Fosterville) operates a gold plant in Australia comprising of a crushing and grinding circuit (SAG mill with a closed loop cyclone classification circuit) followed by flotation, bacterial oxidation and leaching circuits. The lack of surge capacity between the grinding and flotation circuit and restrictions on crushing operations due to noise constraints resulted in unique set of challenges, that required the implementation of a novel control solution using advanced instrumentation.
