摘要:
This invention relates to a froth flotation process for recovering scheelite from scheelite ores. This invention comprises adding a sulphonate collector or a mixture of a sulphonate collector and a fatty acid collector to a pulp containing the ores, selectively floating the scheelite from the ores and recovering the flotation concentrate thus obtained.
