Tungsten processing Britannica

2021-5-16  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% .
