Abstract

The utility model belongs to the technical field of flotation of metal ore body and specifically discloses a coppering ore floating system. The system is composed of a ball mill, a grader, agitating barrels, a rough flotation machine, a fine floatation machine and a scavenger flotation machine, wherein there are at least two agitating barrels which are connected in series, and preferably, there are two agitating barrels only. The utility model adds agitating barrels between the grader and the agitating barrel, prolongs the agitation time of ore pulp and exerts the drug action of the drugs adequately. The production practice proves that a copper ore floating system added with one agitating barrel reduces the copper tails flotation index from the original average 0.2% to the present average 0.17%, so as to greatly reduce the resource loss.

Description

A kind of copper ore floatation system

Technical field

The utility model belongs to the flotation technology field of metal ore body, has been specifically related to a kind of copper ore floatation system.

Background technology

Copper raw ore taste is often lower, and conventional copper ore floatation system is that scalping, a dosing are stirred, through roughly select-selected-after scanning copper concentrate and copper mine tailing.Short because of mixing time in the agitator, medicament can not be given full play to its due effect, and the copper mine tailing floatation indicators that causes adopting this system to floatingly select is often higher, does not satisfy the requirement of subsequent handling to the copper mine tailing, causes a large amount of losses of resource.

The utility model content

For overcoming the deficiencies in the prior art part, the purpose of this utility model just is to provide a kind of copper ore floatation system, reduces copper mine tailing floatation indicators, reduces resource loss.

For achieving the above object, the technical scheme that the utility model is taked is as follows: a kind of copper ore floatation system, by ball mill, grader, agitator, roughly select flotation device, precision sorting flotation machine, scavenging flotation machine is formed, the feed port of described ball mill links to each other with last process, the gape of ball mill connects grader, the rough mouth of grader returns with the feed port of ball mill and links to each other, the fine iron ore hole of grader connects agitator, the outlet of agitator connects roughly selects flotation device, the foam mouth of roughly selecting flotation device connects precision sorting flotation machine, the ore pulp mouth of roughly selecting flotation device connects scavenging flotation machine, the ore pulp mouth of precision sorting flotation machine and the foam mouth of scavenging flotation machine return jointly with the import of roughly selecting flotation device and link to each other, the foam mouth of precision sorting flotation machine and the ore pulp mouth of scavenging flotation machine link to each other with next procedure respectively, its special character is to have at least two agitators, is connected in series successively between each agitator.

As preferably, two agitators are arranged.

The utility model is newly-increased between grader and agitator to be added with agitator, has prolonged the mixing time of ore pulp, and medicament is given full play to drug effect.By production practices, the copper ore floatation system that increases an agitator can make copper mine tailing floatation indicators by original average more than 0.2%, on average drops to now 0.17%, has significantly reduced resource loss.

Description of drawings

Accompanying drawing is a configuration schematic diagram of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in drawings, a kind of copper ore floatation system, by ball mill 1, grader 2, agitator 3, roughly select flotation device 4, precision sorting flotation machine 5, scavenging flotation machine 6 is formed, the feed port of described ball mill 1 links to each other with last process, the gape of ball mill 1 connects grader 2, the rough mouth of grader 2 returns with the feed port of ball mill 1 and links to each other, the fine iron ore hole of grader 2 connects agitator 3, the outlet of agitator 3 connects roughly selects flotation device 4, the foam mouth of roughly selecting flotation device 4 connects precision sorting flotation machine 5, the ore pulp mouth of roughly selecting flotation device 4 connects scavenging flotation machine 6, the ore pulp mouth of precision sorting flotation machine 5 returns jointly with the import of roughly selecting flotation device 4 with the foam mouth of scavenging flotation machine 6 and links to each other, the foam mouth of precision sorting flotation machine 5 links to each other with next procedure respectively with the ore pulp mouth of scavenging flotation machine 6, in order to prolong the mixing time of ore pulp, make medicament give full play to drug effect, between grader 2 and agitator 3, be connected in series again an agitator 3 '.

The course of work of native system: the copper raw ore directly joins in the ball mill 1 by feed port, the ore pulp of discharging behind ball mill 1 ore grinding enters grader 2 to carry out classification and sorts; the defective particle that sorts out; proceed to grind as rough ball mill 1 feed port that returns of copper; the qualified particle that sorts out simultaneously; as the thin ore deposit of copper enter agitator 3 '; enter after the dosings in 3 and roughly select flotation device 4; roughly select the foam that scrapes and enter precision sorting flotation machine 5; primary slurry enters scavenging flotation machine 6; selected ore pulp and to scan the foam that scrapes be the copper chats; return together and roughly select flotation device 4 and continue to roughly select; the selected foam that scrapes is the floating product copper concentrate; the ore pulp of scanning discharge is the copper mine tailing, respectively with copper concentrate; the copper mine tailing is delivered to next procedure.

Claims

1. copper ore floatation system, by ball mill, grader, agitator, roughly select flotation device, precision sorting flotation machine, scavenging flotation machine is formed, the feed port of described ball mill links to each other with last process, the gape of ball mill connects grader, the rough mouth of grader returns with the feed port of ball mill and links to each other, the fine iron ore hole of grader connects agitator, the outlet of agitator connects roughly selects flotation device, the foam mouth of roughly selecting flotation device connects precision sorting flotation machine, the ore pulp mouth of roughly selecting flotation device connects scavenging flotation machine, the ore pulp mouth of precision sorting flotation machine and the foam mouth of scavenging flotation machine return jointly with the import of roughly selecting flotation device and link to each other, the foam mouth of precision sorting flotation machine and the ore pulp mouth of scavenging flotation machine link to each other with next procedure respectively, it is characterized in that having at least two agitators, be connected in series successively between each agitator.
