Separation of Tailing by Gravity

Flowsheet composed of one roughing and one cleaning by spiral chutes is generally applied for tailings like nickel, lead, zinc, tungsten and tin and valuable metals can be recovered.

Case Analysis

At a large-scale nickel ore concentrator with a daily capacity of 1200 tons, 16 sets of BL1500 spiral chutes were adopted in flowsheet composed of one roughing and one cleaning for tailing with 0.3% Ni. As a result, rough concentrate of 1.2%(Ni) can be obtained and sent back to grinding and flotation process, and the overall recovery rate can be improved by above 1.37%.
