Description

(5) DECLINER

one

The invention relates to the enrichment of minerals and can be used for the classification and desliming of finely divided materials, in particular sulfide-containing materials, at the beneficiation plants.

Known hydroclassification, including a bath with a xonic bottom, loading and unloading nozzles, a drainage device, nozzles for supplying water and air, an aerator located in the lower part of the bath, as well as the supply pipe, and the lower part of this pipe is made with a conical mouth

The disadvantage of such a hydroclassifier is the low efficiency of the process when classifying sulphide-containing magnetite ores and concentrates, due to the possibility of separation into a separate product.

sulphide minerals, similar in magnitude to magnetite.

The aim of the invention is to improve the separation accuracy due to the separation of sulphide-containing minerals.

This goal is achieved by the fact that the waste separator is equipped with an additional aerator installed in the upper part of the bath, an annular chute with a discharge pipe for the sulfide-containing product and a pulp dispenser, and the pulp dispenser is made in the form of two cones connected by bases.

The discharge pipe can be made in the form of a siphon.

Aerators can be made in the form of elastic perforated pipes and are arranged in cages.

The drawing shows a declarator, cut.,

The deslaster includes a bath 1 with a conical bottom and a drain chute 2, a loading pipe 3 with an annular chute k, a pulp distributor 5 located in the upper part of the pipe 3, aerators 6, one of which is installed in the upper part and the other in the lower part of the bath 1, nozzle. 7 for supplying water, a sand discharge device made in the form of siphons 8. Aerators are packed in cages and can be made in the form of elastic perforated tubes, as well as disks or sectors with a porous structure made of rubber, silicate compounds or plastics.

Deschlamator works as follows.

The pulp from the slurry pipe through the distributor enters the loading tube where the aerator is installed. Faced with an upward flow of finely dispersed air bubbles, sulphide minerals are transported last to the pulp surface and, with the help of a conical distributor surface, are thrown into an annular groove.

The sweetened product enters the drainage bath. Decalcation is carried out in an upward flow of liquid and gas (air blowing into the upper part of the sludge bath. Water is forced into the bath of the declarant through the nozzle 7, and the air is supplied with an aerator installed in the bottom of the deatator bath.

Purified sands are loaded with siphons, and the slimes are poured into the drainage chute.

The advantages of the proposed declarer are the increased inconvenience in the separation of sludge from magnetite concentrate, as well as an improvement in the quality of magnetite concentrate due to the removal of sulphide-containing minerals.
