| titleOfInvention | Method of sulfide extraction from tungsten-containing ores |
| abstract | Usage: mineral processing, ore flotation According to the invention: the pulp is conditioned with modifiers, nitrogen-containing carboxylic acid and sulfhydryl collector. A blowing agent is introduced. Sulfides are recovered in the foam product. As a nitrogen-containing carboxylic acid, a- (indolyl-3-thio) butyric acid is introduced in a ratio with the sulfhydryl collector from 1: 5 to 1:75. 1 C.p. f-crystals, 2 tab. |
