Froth flotation of scheelite – A review ScienceDirect

Froth flotation of scheelite has regained new focus since the 2010s and research regarding floatability and reagents has made great progress over the years The main objective was and remains the selective flotation of scheelite from other calciumbearing minerals, inThe production of highgrade scheelite concentrates from lowgrade ores involves a set of operations to eliminate the undesirable minerals The present work includes as main goals the study of the effect of (i) meteorization of the ore, (ii) pH during the grinding, (iii) the amount of soda ash in grinding process, (iv) the depression or previous flotation of sulphides, (v) and theScheelite Flotation From Tarouca Mine Ores: MineralFor comparison, the mixed ore flotation results of using single OPS as collector is also presented in Table 2 As shown in Table 2, the WO 3 grade is only 5249% and is significantly lower than that using mixed OPS/BHA when the scheelite recovery is similar The results suggest that an effective separation of scheelite from calcite can beFlotation separation of scheelite from calcite using mixed

A scheelite concentrate is recovered from a scheelite ore containing silicate minerals and other calcareous minerals by froth flotation which process comprises grinding the ore sufficiently fine to liberate the scheelite grains, pulping the gound ore with water to form a slurry containing between about 20% and about 40% solids by weight, sequentially conditioning the slurry with at least oneScheelite is quite readily floatable with fatty acids in an alkaline circuit with soda ash and sodium silicate Other nonmetallic minerals such as calcite and fluorspar are often present in the ore, so a high grade scheelite concentrate is difficult to produce by flotationExtraction of Tungsten from Scheelite OreA flotation process for recovering scheelite (calcium tungstate) from a low grade slimey ore containing other calcareous minerals such as calcite is described The scheelite is selectively flocculated by conditioning the ore pulp at a high pH, using intense agitation, usually prolonged, in the presence of predetermined quantities of a deflocculating agent, a source of polyvalent cations toUSA Recovery of scheelite from ores by flotation
