The Critical Role of Pulp Density on Flotation Separation,
In nickel-copper sulfide ore processing, serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment during flotation [].Large amounts of serpentine in the flotation concentrate reduces the effectiveness of smelting, often resulting in the imposition of smelter penalties on mineral processing companies [].The effect of a novel depressant on the separation of talc,,for flotation separation of copper/nickel minerals, respectively. The Cu/Ni bulk flotation used 1kg ore to obtain a Cu/Ni bulk concentrates. After wet grinding, the desired amounts of reagents were added to the slurry while agitating at about 1900 rpm andthe slurry was conditioned for 6 min. During the batch flotation tests, the room temperature still keep constant at 25 ± 1 ℃. Airnickel and copper flotation - purpleacademy.in,nickel and copper flotation. Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4 Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickelbearing iron sulphides which report to the flotation tails.
