Applied materials:non-ferrous metals, ferrous metals, precious metals, non-metallic mineral, chemical raw materials, etc.

nickel flotation

Sep 24, 2020· A basic principle for determining theflotationprocess is that it is better to allow copper to enter thenickelconcentrate, and to avoidnickelentering the copper concentrate as much as possible. Because thenickelin the copper concentrate is lost during the smelting process, the copper in thenickelconcentrate can be completely recovered We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, you can click the button to consult us.

    Innickel-coppersulfide ore processing, serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment duringflotation. Large amounts of serpentine in theflotationconcentrate reduces the effectiveness of smelting, often resulting in the imposition of smelter penalties on mineral processing companies [ 2 ]
