Flotation Wolframite Ores
Apr 16, 2021 After the wolframite is separated by gravity separation, its crude concentrate often contains scheelite, cassiterite, molybdenite, bismuthite, pyrite, chalcopyrite, sphalerite and other minerals. Cassiterite and bismuthite are enriched in high-grade coarse concentrate. These associated minerals are harmful impurities for tungsten concentrates, but there are also many useful minerals.
According to Table 1, wolframite is the main component of tungsten ore, accounting for 94.77 , and thus Cassiterite Flotation - Tin Oxide - 911 Metallurgist Jul 06, 2015 Cassiterite flotation is nearly always performed in an acid environment, the exact value depending on the ore source and collector to be used.
