Abstract
The present invention provides a waste-residue copper-selection tailing disposal processing method; firstly, the tail ore is concentrated for classification by a whirlcone; the bottom stream of the whirlcone directly flows into a ceramic filter to be filtered; the ore slag after the filtering is recycled for use, and the filtering solution enters into a concentrated pool; and a part of the filtering solution overflows into the concentrated pool to be concentrated, and another part enters into the ceramic filtering machine; the bottom stream of the concentrated pool flows into a cylindrical filtering machine to be filtered; the ore slag after the filtering is recycled for use, and the filtering solution flows into the concentrated pool; the overflowed solution that flows into the ceramic filtering machine is filtered, and the ore slag is recycled for use, and the filtering solution flows into the concentrated pool; the whirlcone is an FX100-GK*50 concentration-type whirlcone. The waste-residue copper-selection tailing disposal processing method not only can guarantee the normal operation of the concentrated pool, but also favors the environmental protection.
Description
Technical field:
The present invention relates to a kind of tailings processing method for selecting copper from waste slag.
Background technology:
At present, the method for mine processing mine tailing is to utilize concentrator to concentrate with filter to filter.Because the disseminated grain size of copper mineral is thinner in the waste residue, the copper mineral of 0.043mm-0.020mm grade accounts for more than 75%, so waste residue requires enough mogs (325 orders are more than 85%) in flotation operation; Mine tailing at first gets into concentrator, and it is meticulous that ore grinds, and sinking speed is slow; The concentrator overflow water runs and mixes; Overflow water can not carry out recycle, directly effluxes and contaminated environment, and thickener underflow concentration is unstable in addition; Concentration can not guarantee that more than 65%, this has brought great difficulty to filtration.This process using ceramic filter and drumfilter parallel connection are filtered; It is very poor to be lower than 65% filter effect when following in concentration; Filter board and imitate and to reach design load, and drumfilter is easy to kill the stirring rake in the concentration 50% below, bring many difficulties for production and operation.Get into the ore deposit amount of thickening pond, filter can not be disposed fully, makes thickening pond turnover amount can not reach balance, and the time one is long, and the ore deposit amount that concentrator overstocks is more and more, finally surpasses its load, causes concentrator to run well, and production can't normally be carried out.
Summary of the invention:
The object of the invention just provides a kind of processing method of selecting copper from waste slag mine tailing, and the mine tailing after handling through this method has reduced the pollution to environment.
The object of the invention can be realized through following scheme; At first mine tailing is concentrated classification through cyclone; The underflow of cyclone directly gets into ceramic filter and filters, and the slag after the filtration is recycled, and filtered fluid then gets into thickening pond; An overflow part gets into thickening pond and concentrates, and another part then gets into ceramic filter.The underflow of thickening pond then gets into drumfilter and filters; Slag after the filtration is recycled; Filtered fluid gets into thickening pond, gets into the overflow of ceramic machine filter, and the slag after the filtration is recycled; Filtered fluid then gets into thickening pond, and said cyclone is FX100--GK * 50 concentrated type cyclones.
Advantage of the present invention is: owing to adopt efficient concentrated type cyclone; At first guaranteed the feed ore concentration of ceramic filter, under the high concentration more than 70%, the platform of ceramic filter is imitated and is rised appreciably; The cyclone spillway discharge concentrates the back through thickening pond and gets into drumfilter; Part gets into ceramic filter, has guaranteed the turnover amount balance of thickening pond so fully, and thickening pond also just can run well; Because getting into the ore pulp of thickening pond is the overflow of cyclone, granularity is thinner, and sinking speed is slow, and after adding lime and flocculant, it is clear that the thickening pond overflow water becomes rapidly, recycle again, and directly effluxing can not have any influence to environment yet; The thickening pond underflow gets into drumfilter, owing to advance to starch fine size, viscosity is bigger than normal, therefore also can not cause rake to kill.
Claims (1)
1. a tailings processing method for selecting copper from waste slag is characterized in that at first mine tailing being concentrated classification through cyclone, and the underflow of cyclone directly gets into ceramic filter and filters; Slag after the filtration is recycled, and filtered fluid then gets into thickening pond, and the overflow part of cyclone gets into thickening pond and concentrates; Another part then gets into ceramic filter, and the underflow of thickening pond then gets into drumfilter and filters, and the slag after the filtration is recycled; Filtered fluid gets into thickening pond, gets into the overflow of ceramic machine filter, and the slag after the filtration is recycled; Filtered fluid then gets into thickening pond, and said cyclone is FX100-GK * 50 concentrated type cyclones.
