Copper recovery improvement in an industrial flotation

Obtaining high recovery in copper flotation plants has been always under investigation in recent years. Misreported copper into tailing dramatically declines copper recovery. This study aims to find the possible reasons of copper loss to tailing and present the methods to improve the performance of the Sarcheshmeh copper plant flotation circuit.

Ultrasound treatment on tailings to enhance copper

It has been shown that this microjet possesses great capacity to erode a surface which would remove contaminants on the surfaces of the particles, thus improving the efficiency of the concentration process. This study suggests that the cavitation phenomenon caused by ultrasound could improve the flotation tailings of copper sulfides.

Increase Gold recovery in Copper flotation Froth

Your statement reads that you are recovering 0.8% of the gold in the copper flotation concentrate; which implies you are losing over 99% of the gold. Most operations I have dealt with the terms would be 0.8% gold as a grade in the concentrate. We had a similar interest in improving silver recovery floating with pb concentrate. Studies done

Improving the efficiency of oxide copper–cobalt ores

Abstract Sulphidising flotation of oxide copper–cobalt ores with sodium hydrosulphide used as sulphidising agent is common practice in Katanga, Democratic Republic of Congo. From laboratory investigations, sodium hydrosulphide proved to enhance flotation selectivity of copper and cobalt towards the gangue minerals, while ammonium sulphide emerged as a strong non-selective sulphidiser.
