  • Extraction of Tungsten from Scheelite Ore

    2016-5-10  Scheelite is quite readily floatable with fatty acids in an alkaline circuit with soda ash and sodium silicate. Other non-metallic minerals such as calcite and fluorspar are often present in the ore, so a high- grade scheelite concentrate is difficult to produce by flotation. Sulphides, if present, must be floated ahead of the scheelite

    2008-9-5  Abstract. A “design-of-experiment” (DOE) approach was used to study the purification of a scheelite ore concentrate in HCI. The ore concentrate contained about 65% CaWO 4, 18% CaCC 3, 14% Ca 10 (PO 4) 6 (OH) 2, and 3% SiO 2.In addition to these major phases, the ore concentrate also contained trace amounts of toxic elements such as arsenic, lead, and uranium.
