Extracting Tungsten from Wolframite Gold Ore

The flowsheet study previously shown for tungsten was devised for a simple tungsten ore free of other heavy minerals. The first consideration of any tungsten ore is to recover the mineral as coarse as possible and avoid sliming and overgrinding by stage crushing and grinding. This is necessary because of the friable nature of all tungsten minerals.
