ABSTRACT:
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 to fatty acid is 0.5:1 to 2.8:1.
