ORE SUSPENSION SEPARATION COMPLEX Russian patent published in 2012 - IPC B04C7/00 C22B3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to selective separation of ore suspensions. Proposed complex comprises unit of hydraulic cyclones with control valves, electrically driven pump, suction and pressure pump lines, coarse ore feed conveyor, ore fine grinder, selective classifier, sump, service water supply system, control valves and automatic control system. Every hydraulic cyclone is shaped to tapered cylinder housing with intake chamber at its top communicated via feed branch pipe with pulp distributor and provided with colder with drain branch pipe and sand bed communicated, at its bottom, via sand manifold, with similar beds of other cyclones. Ore fine grinder inlet is communicated with coarse ore intake while its outlet is communicated wit selective classifier having two outlet ducts, one being connected with sump and another one being communicated with grinder. Sump is communicated via T-joint and suction pulp line with pressure pipeline of water supply system to switch over to pulp wash-out in sump while turbo pump is communicated with turbo delivery pump.

EFFECT: higher efficiency and quality of separation, power savings, perfected design.
