 — Copper ore powder flotation machine can guarantee better stability index for refractory and complex copper ore or high-grade concentrate. In the flotation process, the equipment parts wear less, the …

Flotation equipment is the key equipment for separating copper minerals from gangue minerals, including flotation machine, stirring tank and flotation column. The concentrator …

 — GOLD RECOVERY BY FLOTATION. A test on a sample, crushed to pass a screen of 120 holes per linear inch, containing $37 gold and 4.8% copper, gave a recovery by flotation alone of 90% of the gold and 98.5% of the copper, but left $8 gold in the tailing. The concentrate carried 44% insoluble matter, which could be reduced by re-treatment.

The copper ore flotation machine is the main equipment used in the beneficiation processing of copper ore, which generally adopts a flotation production line. Designed with multi-stage separation tanks, the copper ore flotation machine gradually completes the entire flotation process, optimizing it in a cascading manner.

Copper Ore Beneficiation Production Line. Capacity : 20-3000t/d Applicable Materials : Copper ore Applications: Metal mineral resources development, materials science, chemical industry and other fields. Case Description: Copper ore beneficiation is a process in which copper concentrate is obtained by flotation, magnetic separation and gravity separation.

3. Flotation separation: After stirring, the pulp enters the flotation machine, and the collector with good selectivity is added for flotation to obtain qualified copper concentrate. 4. Filter & dewatering: The copper concentrate pulp obtained by flotation is transported to a high-efficiency thickener for concentration. Finally, the ...

The results show that the flotation with ethanol can greatly enrich copper, and the copper content in metal-rich concentrate can be increased by 182.3 %, with a copper recovery rate of 85.1 %. Increasing the solid-to-liquid ratio and applied voltage can increase the deposition rate of copper, but affects the stability of electrodeposition.
