scheelite flotation process

US Patent for Scheelite flotation process Patent

1. A process of separating scheelite from gangue in an ore, which process comprises grinding the ore with 4 to 10 grams of an alkali metal carbonate per kilogram of ore, selectively separating sulphide minerals present in a pulp of the ore and then subjecting the pulp comprising desulfided pulp and pulp liquor to froth flotation to separate selectively scheelite, said flotation being carried

Recovery of scheelite from ores by flotation

A 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

Scheelite Flotation From Tarouca Mine Ores: Mineral

2019-4-15 · The production of high-grade scheelite concentrates from low-grade 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 the

Froth Flotation of Tungsten Ore

2020-12-10 · 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

Extraction of Tungsten from Scheelite Ore

2020-12-9 · High price and ready market for acceptable tungsten concentrates present a very attractive incentive for the mining and processing of tungsten ores. Since all tungsten ores are very friable and slime easily, concentration must take place as soon as the mineral has been liberated by either crushing or grinding methods. Regardless of the care taken in the selection of the flowsheet, a certain

Scheelite flotation production line,Scheelite

Scheelite ore has good floatability, usually caused by the presence of calcium gangue minerals, which makes flotation process more complex. In order to improve the selectivity of flotation process, by adding metal salts, can improve scheelite flotation effect significantly.
