Black tungsten ore flotation reagent-ZN802 Purpose: flotation and recovery of fine tungsten ore slime: good collection, selectivity and low temperature resistance. It has wide applicability to flotation and recovery of fine tungsten ore …
Depending on the deposit, these tungsten ores have a WO 3 content of between 0.3 and 2.5 percentage by weight. Comminution, grinding, flotation and roasting processes can be employed to increase the WO 3 content to approximately 60 %. The remaining impurities are mostly eliminated by means of digestion with sodium hydroxide.
Scheelite (CaWO4) and Wolframite ((Fe,Mn)WO4) are the principal minerals of tungsten, but other important minerals include ferberite (FeWO4) and huebnerite (MnWO4) will also respond to froth flotation.The high specific gravity of these minerals makes many of these ores amenable to gravity concentration methods, however, the fine dissemination of mineral in gangue for some ores may …
