Tungsten processing Britannica
2021-5-5 During the countercurrent flow of the extractant through the solution, tungstate ions transfer from the aqueous phase to the organic phase. The tungsten is then stripped from the extractant into an ammonia solution containing ammonium tungstate. The resultant APT solution is sent to an evaporator for crystallization.

Tungsten Ore Mining Solution - Mineral Processing
In this process, the tungsten fine mud is first desulfurized, and then the coarse concentrate is centrifuged with a centrifugal concentrator. The obtained coarse concentrate is desulfurized again and then enters tungsten flotation or strong magnetic separation. The recovery rate of the obtained tungsten fine mud concentrate is generally about 65% .

Processing of Tungsten Preconcentrate from Low
2008-3-26 Tungsten from the purified leach solution was extracted by 10% Alamine-336 and 10% isodecanol in kerosene. The loaded metal when stripped with NH 4 OH produced ammonium paratungstate (APT) solution which was crystallised to get the crystal of APT. The alkali pressure leach-solvent extraction process was thus found attractive for treating such ...
