Abstract
The invention discloses a titanium placer mineral processing and tailing fast reclamation method. According to the method, titanium placer is subjected to slurry mixing after preliminary screening, then, high-magnet desliming is carried out after fine screening, tailing pulp and coarse titanium concentrate with the TiO2 content being greater than 28 percent are obtained, the tailing pulp is subjected to concentration dehydration, dehydrated tailings with the moisture content being 10 to 15 percent are obtained, and the dehydrated tailings are subjected to mine reclamation in a flat pavement mode or a step mode. The method provided by the invention has the advantages that the TiO2 content in the dehydrated tailings is similar to that of the traditional gravity and magnetic associated process, the titanium mining and dressing recovery rate can be ensured, the requirements of resource comprehensive utilization are reached, the simultaneous mining and the simultaneous reclamation can be realized, the goal of fast reclamation is achieved, the problem of high transportation cost of tailings or tailing pulp is solved, and the reclamation cost is greatly reduced. Any chemical reagent is not added into the titanium placer mining and dressing processes, no pollution is cased on soil, the tailings are adopted for reclamation, the soil does not need to be improved, grass and plants can be directly planted for reclamation, the water consumption by the method is low, and the method is particularly suitable for the mining of titanium placer mine lack of water resources.
Description
Technical field
The present invention relates to a kind of method that titanium placer ore dressing and mine tailing are reclaimed fast, belong to To Mining Development technical field.
Background technology
Titanium placer exploitation and ore dressing, the heavy magnetic combined process flow of current employing obtains concentrated ilmenite and iron ore concentrate, mine reclamation be smooth to goaf after, add fertilizer and solve soil depletion problem, plantation is suitable for local growing plants, reaches object of reclaiming, but still there is Safety of Tailings Dam potential problem, as processed not in time, can damage ecological environment.In addition, because ilmenite concentrate value is lower, mineral reserve belong to opencut, the mineral reserve degree of depth is more shallow, distribution is wide, is difficult to form large scale mining, is difficult to economically meet need of production, therefore be necessary the transportation problem solving tailings dewatering problem, mine tailing or ore pulp, dig up mine to be formed simultaneously, reclaim simultaneously.
Summary of the invention
For solving the problem that can reclaim in time of mine tailing, the invention provides a kind of method that titanium placer ore dressing and mine tailing are reclaimed fast, under the prerequisite ensureing comprehensive utilization of resources, limit mining, limit are reclaimed, and reach the object of reclaiming fast.
The present invention is realized by following technical proposal: a kind of method that titanium placer ore dressing and mine tailing are reclaimed fast, it is characterized in that through following each step:
(1) titanium placer is carried out primary dcreening operation, the solid mineral that removing is greater than 8 millimeters, obtain residue;
(2) residue of step (1) is mixed with water size mixing, obtain the ore pulp that concentration is 28 ~ 35%;
(3) step (2) gained ore pulp is carried out dusting cover, remove the ore of more than 1.5 millimeters;
(4) step (3) is carried out strong magnetic desliming through the ore pulp of dusting cover under magnetic field intensity is 0.65 ~ 0.8T, obtain Tailings Slurry and TiO
2the crude titaniferous concentrate of content > 28%;
(5) step (4) gained Tailings Slurry is carried out thickening, obtain the dewatered tailings that moisture content is 10 ~ 15%;
(6) step (5) gained dewatered tailings is carried out mine reclamation with flush system or staged, wherein tile thickness G reatT.GreaT.GT 0.5 meter, and thickness G reatT.GreaT.GT 1 meter inserted by stepped enclosure wall.
The enclosure wall that the solid mineral of described step (1) is reclaimed for staged is built by laying bricks or stones.
Described step (4) gained crude titaniferous concentrate is delivered to dressing process and is carried out selected.
The water that in described step (5), thickening is deviate from returns operation of sizing mixing.
The advantage that the present invention possesses and effect: method provided by the invention makes TiO in dewatered tailings
2content is close with traditional heavy magnetic combined process flow, can ensure the titanium selecting and purchasing rate of recovery, reach the requirement of comprehensive utilization of resources, can realize digging up mine simultaneously, reclaiming simultaneously, reach the object of reclaiming fast, solve mine tailing or mine tailing ore pulp cost of transportation problem, greatly reduce charges for recultivation and use.Adopt method process of the present invention to obtain dewatered tailings, reclaimed in a large amount of mine tailing scene, reduce Tailings Dam capacity, reduce mine selecting and purchasing construction investment.Because whole selecting and purchasing flow process does not add any medicament, soil is not polluted, adopt mine tailing to reclaim, do not need to improve soil, directly can plant grass, plant is reclaimed, this method water consumption is less, the titanium placer mountain exploitation that especially suitable water resource is shorter.
