METHOD OF FLOTATION SEPARATION OF SULPHIDES COMPRISING NOBLE METALS FROM COMPLEX IRON-CONTAINING ORE AND COMPOSITE MATERIAL TO THIS END Russian patent published in 2010 - IPC B03D1/00

Abstract RU 2393925 C1

FIELD: process engineering.

SUBSTANCE: invention relates to ore preparation by foam flotation method, particularly to flotation separation of sulphide copper-nickel pyrrhotine-containing ore and can be used in flotation preparation of the other complex materials containing sulphide minerals of copper, nickel and iron. Proposed method comprises ore pulping, processing pulp by sulfur-containing collector and flotation. Said sulfur-containing collector represents a composite material consisting of non-polarity collector and oil sulphides with the following components ratio, %: non-polarity collector - 75-80, oil sulphides - 20-25. Depressor additive consisting of ethylene polymer with vinyl ether dissolved in high-boiling hydrocarbon is added to composite material to reduce hardening temperature.

EFFECT: increased yield of noble and non-ferrous metals and higher efficiency of proposed process.
