The accompanying drawing explanation
Fig. 1 reclaims the flow chart of the Novel mineral system of tungsten according to tungsten slurry of the present utility model.
Fig. 2 is the equipment contact figure according to Novel mineral system of the present utility model.
The specific embodiment
As shown in Figure 1-2, the beneficiation method of implementing to reclaim according to tungsten slurry of the present utility model tungsten comprises the following steps: at least the gravity treatment tungsten slurry, is concentrated into C=15-20%, sulphide ore is reclaimed in flotation, add medicament to stir reunion, gravity treatment, tungsten concentrate.One of them embodiment is as follows:
A. adopt concentrator (as concentrator) to be concentrated into 15%-25% gravity treatment tungsten slurry mine tailing, pump into agitator, then feed floatation equipment, and add butyl xanthate 150-200g/t, 2# oil 60g/t, go through one roughing, once purging selection, primary cleaning flotation, reclaims sulphide ore.
B. flotation tailing pumps into or certainly flows into agitator, and adds successively calgon 2kg/t, No. 3 collecting agent 50g/t, G type flocculant 10g/t, stirs 6-10 and divides.
C. after stirring, ore pulp feeds centrifugal ore separator, carries out gravity treatment, obtains tungsten concentrate.
Laboratory's small-scale test example
Get the tungsten slurry primary sample, WO
3Grade 0.23%.
Adopt traditional process, go through table concentration, one roughing, once purging selection, obtain tungsten concentrate WO
3Grade 15.6%, the rate of recovery 54%.
Adopt the utility model flow process, obtain tungsten concentrate WO
3Grade 15.7%, the rate of recovery is increased to 76%.
According to the utility model, the concentrated rear flotation of tungsten slurry is reclaimed to sulphide ore.Flotation tailing adds and is applicable to the medicament stirring.The appropriate methodologies such as the rear ore pulp employing of stirring gravity treatment sort to obtain tungsten concentrate.It is other that the utility model is applicable to the tungsten slurry spoil reclaming that gravity treatment reclaims, and the tungsten slurry fineness is less than 0.1mm.
According to the utility model, the tungsten slurry mine tailing adds specific medicament to size mixing after adopting flotation comprehensively to reclaim sulphide ore.At first, add dispersant, make various ore particles in ore pulp in ore pulp, distribute more even.Then, add applicable collecting agent, its effect also is adsorbed in fine fraction tungsten mineral surface.Finally, add specific flocculant, preferentially catch the collecting agent molecule, the bulky grain mineral that make simultaneously the fine fraction tungsten mineral reunite and select for easily, and other gangue minerals do not form agglomerate, increase its difference of specific gravity, then adopt gravity treatment to sort to obtain tungsten concentrate.Solution is difficult to sort problem because of what fine fraction tungsten and gangue mineral similar weight were brought.
