Gravity concentration

Control the jigging time and abandon tails by shaker is the core of the gravity concentration. gravity concentration process structure of wolframite’s triple jigging and multi-level shaker has basically no change over years, based on the characteristics and nature of ore and flows, improve the efficiency of wolframite ore beneficiation by improving the gravity concentration process parameters. Such as reasonable adjustments of shaker’s grain size range, improve the efficiency of hydraulic classification to ensure the grain size range of shaker, use efficient jigging and screening equipments.

 

Selection

Wolframite selection commonly uses flotation - gravity concentration or flotation - gravity concentration- magnetic separation and recycle the accompanying elements in selection.

In the selection operation, generally through the coarse and fine fractions Taifu and removal of sulfide ore flotation, Taifu and Jifu sulfide ore combine and enter the flotation of sulfide ore, after which wolframite further produce wolframite concentrate. If there are scheelite or cassiterite in wolframite concentrate, select wolframite concentrate, scheelite concentrate and tin concentrate by the flotation - gravity concentration- magnetic separation (electric separation). Most wolframite concentrators selection workshop do intermittent operation, the process is more flexible, and some are even complicated. The equipment used are more special, such as horizontal mixer, vertical float, etc., which is rare in not ordinary concentrators.
