Strengthening and readsorption of collector - New Technology of trialkali selectively desorbed off the drug direct selection 

 

Add collector before coarse scheelite concentrate selection, strengthen tungsten ores and readsorb collector; after that add trialkali modifying agent, strengthen selective desorption, reagent removal and inhibition of non-target minerals. Direct flotation without dilution, desliming and reagent removal, simply the processes, recover scheelite efficiently.

 

Tungsten fine mud cyclone concentrated - normal flotation - centrifuge selection short process of new technology

Replace the original complex process of "normal flotation - Heated selection - weak magnetic flotation - intensity magnetic flotation - shaker re-election", simplifying the process, greatly improve the recovery of tungsten fine mud.

 

Isomorphous rich-molybdenum variant scheelite flotation new technology

For molybdenum tungsten isomorphous scheelite’s problem that the selection is difficult and cannot develop and use the resources, the use of TA-3 effects collector made flotation of such resources successful and construction, which makes stay mine resources become available.

 

Basic Theory Study and Innovation

Through the study of wolframite and scheelite flotation kinetics, put forward diversion velocity model innovatively, so the asynchronous flotation separation process of two tungsten minerals was proposed.

Calculate and optimize hydroxamic acid collector structure parameters by quantum chemistry, analyze the effects of the molecular structure of the collector on wolframite and scheelite flotation, as collector optimization basis.

 

The process mineralogy basis of coarse scheelite concentrate heating and normal selection was proposed.
