METHOD OF FLOTATION IRON TUNGSTEN MINERALS from the tail of gravity beneficiation of ores

摘要

1. A process for the flotation of iron-containing minerals tungsten gravitational tailings comprising desliming initial pulp slurry conditioning with soda ash and the sodium soap of the fatty acid collector, tall oil example, at a pulp density of 30% solids and tungsten flotation of minerals, characterized in that, before feeding sodium soap fatty acid collector, together with soda ash, an aqueous solution of sodium hydroxide, and the flotation water is carried out at a temperature from 20 ° C to 8 ° C.2. A method according to claim 1, characterized in that the ratio of soda ash, caustic soda and sodium fatty acid soap is from collector 500:. 150: 200 to 500: 250: 200.
