METHOD OF ORE FLOTATION Russian patent published in 2014 - IPC B03D1/02 

Abstract RU 2524701 C1

FIELD: mining.

SUBSTANCE: method of flotation extraction of platinum group metals from ores or cakes of pyrrotine leaching with application of flotation reagents-collectors. Mixes of organic compounds are used as flotation reagents wit definite experimental computer parameters: dipole-dipole interaction should -2.7717 to 0.4956, ј Van der Waals interaction from 2.2390 to 8.8701, not ј Van der Waals interaction from -0.3746 to 1.7483, flexure of valence angles from 2.4600 to 3.1866, stretching of valence bonds from 0.2580 to 0.7430 and steric energy from 6.1198 to 8.6639 ccal/mol.

EFFECT: higher efficiency of flotation and selection of reagents.
