A process for separating scheelite from gange wherein the ore is ground with 0.4 to 10 grams of alkali metal carbonate per kg. of ore, forming a pulp and removing sulfide minerals from pulp liquor. Carrying out froth floatation in the presence of paraffin oil, 0.1-0.4 gram of fatty acid per kg. of ore and 3.2-5.5 grams of sodium silicate per kg. of ore wherein the weight ratio of paraffin oil ...

About this result

Dec 10, 2017  Flotation separation of scheelite from calcite is difficult due to the similarities in their surface properties. In this work, the flotation behavior of scheelite and calcite using oxidized paraffin soap (OPS), benzohydroxamic acid (BHA) and the mixed OPS/BHA collectors was investigated through micro-flotation experiments.

Nov 01, 2016  1. Introduction. Scheelite CaWO 4, which is the most important tungsten-containing mineral, usually coexists with other calcium-containing gangue minerals in ore deposit.Among the gangue minerals, calcite is the most common one. Flotation is usually used for the separation of scheelite from calcite (Deng et al., 2016, Y. Gao et al., 2016).However, the flotation separation is difficult since ...

Extraction of Tungsten from Scheelite Ore

May 10, 2016  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. Conclusion
