360～70% hair concentrate, and the mine tailing after the gravity separation only contains Wo
30.05～0.08%, contain Sn0.005%, abandoned because of content is low and drain, and in existing technique of preparing, the effective process of the economical and convenient that can reclaim this low tungsten mine tailing is not also arranged, thereby cause the waste of resource.
The employing blanket sluice gravity separation process that the present invention proposes reclaims tungsten, tin mineral from gravity tailings, can obtain grade and contain Wo
320～30%, the hair concentrate that contains Sn1.0～2% realizes that economical and convenient reclaims the purpose of tungsten ore resource effectively.
Narrate process of the present invention and apparatus structure below.
The blanket sluice ore dressing be use the principle of film concentration technology the flannelette blanket bedding on cement groove face that certain slope is arranged or wooden groove face, just become blanket sluice, when flow of slurry is crossed blanket sluice, the ore particle that the proportion granularity is different is in the different flow of slurry retes, thereby in ore pulp or make subsiding movement, or slide at bottom land, or do to continue the suspension jumping or make continuous suspended motion, the mineral of light specific gravity along flow of slurry to speed greater than heavy mineral speed, to the sinking speed of bottom land then less than heavy mineral sinking speed, in the blanket sluice since flannelette blanket to have fine hair long, approximate number is many, close characteristics distribute, when flow of slurry is crossed flannelette blanket, because the effect of fine hair, little to granularity, heavy mineral have stronger adhesive capacity, and granularity is little, heavy mineral in flow of slurry owing to eluriate, isolate, bore the effect in crack and be easy to heavy to bottom land, easily attached on the flannelette blanket, therefore, thus can the mineral that proportion is different not being enriched in to realize sorting reclaiming in the homogeneous turbulence rete obtains hair concentrate of high grade.
Fig. 1 is a process chart of the present invention, and the ore pulp of gravity tailings (contains Wo
30.05～0.08%, contain Sn0.005%) discharge by the gradient 3～6%, entering blanket sluice after shunting roughly selects once, it is selected with blanket sluice that the rough concentrate of enrichment is collected the back on the flannelette blanket, it is selected to carry out second time with blanket sluice again after the hair concentrate that is obtained is collected, through twice selected after mao concentrate grade of acquisition for containing Wo
320～30%, contain Sn1.0～2%.The mine tailing slurry that gravity tailings slurry flows out through blanket sluice is roughly selected after and twice selected mine tailing slurry that flows out enter blanket sluice again and scan once, and the acquisition rough concentrate uses blanket sluice selected twice again, obtains grade equally for containing Wo
320～30%, contain the hair concentrate of Sn1.0～2%, the tungsten in the gravity tailings, tin mineral effectively obtain reclaiming.
Method of the present invention is carried out on the blanket sluice device, Fig. 2 is a blanket sluice apparatus structure plane, chute is the cement groove face, and the gradient is 2～5%, bedding flannelette blanket on the groove face, flannelette blanket is for containing cotton 70～100%, fine hair length perpendicular to the flannelette blanket face is 1～10 millimeter, and the flannelette blanket area that is used to the every sulculus of blanket sluice (3) roughly selecting and scan is for long 8～10 meters, and is wide 0.8 meter, have 7～10 sulculuses, the flannelette blanket area that is used for selected blanket sluice (5) is long 15 meters, wide 0.8 meter.
The invention has the advantages that it is gravity flow ore-dressing technique process, need not plant equipment and power, technology is simple, device is simple, processing ease, the cost poor benefit is good, method of the present invention can also reclaim valuable mineral under the big mine-supplying quantity situation in big grade scope, by simple repetition 3～4 times are thick selected, can make the concentration ratio of the valuable mineral in-200 order grades reach 125, the rate of recovery reaches 23%, and method of the present invention also can be applied to other mine that gravity tailings is arranged and reclaim the bigger useful metal mineral of proportion such as bismuth, molybdenum, tantalum, niobium at low cost.
