Abstract
Disclosed is a tin-tungsten ore selection method. The method comprises the following steps that tin-tungsten ore is ground to achieve partial monomer separation, and then the jigging branch separation technology is adopted for ore separation to obtain coarse grain heavy ore and fine grain aggregation, wherein the coarse grain heavy ore is monomer tin-tungsten ore with the coarse granularity and rich aggregation with the large specific gravity, and the fine grain aggregation is monomer tin-tungsten ore with the fine granularity and lean aggregation with the small specific gravity; then, separation is performed on the coarse grain heavy ore and the fine grain aggregation, and reselection and recycling of tin and tungsten are achieved. By the adoption of the tin-tungsten ore selection method, tin-tungsten ore can be effectively prevented from being excessively ground or excessively powdered; the technical problems that the main metal ore level is low, the insetting grain size thickness is not uniform and separation is hard are solved; and the fine ore quality and the tin-tungsten recycling rate are better considered, and the high fine ore level and the ore selection recycling rate are obtained.
Description
Technical field
The present invention relates to non-ferrous metal ore technical field, particularly, mineral easy mistake honed powder, mineral disseminated grain size plucked, tungsten tin low for the main metal content of raw ore are difficult to the beneficiation method of the tungsten tin mine be separated.
Background technology
Tungsten tin mine is brittle mineral, very easily crosses honed powder, bring inconvenience to ore dressing process in mineral process, and preventing tungsten tin mine thing from crossing, honed pulverizing and microfine tungsten tin sorts is the technical barrier that world's ore dressing field is generally acknowledged.In tungsten tin intergrowth deposit, in order to synthetical recovery tungsten tin mine thing, generally raw ore is milled to basic monomer and dissociates, adopt jigging machine or spiral chute to throw tail in advance.When tight, the main metal content of tungsten tin mine thing symbiosis is low, disseminated grain size plucked time, mineral being milled to monomer dissociation easily causes metal to cross honed powder, the particulate tungsten tin mine thing gravity treatment difficulty crossing powder reclaims, causes the rate of recovery on the low side, is difficult to obtain desirable mineral processing index.
Summary of the invention
The object of the present invention is to provide a kind of beneficiation method of tungsten tin mine thing,, mineral disseminated grain size plucked low for main metal content, adopt the sorting of thickness branch to improve the beneficiation method of concentrate grade and the rate of recovery, honed powder can be prevented, reclaim tungsten tin mine thing preferably.
The present invention achieves the above object by the following technical solutions: a kind of beneficiation method of tungsten tin mine, is characterized in that: in raw mineral materials used Sn content be 0.083 ~ 0.32%, WO

(5) the tungsten tin rough concentrate 2 that the tungsten tin rough concentrate 1 step (2) obtained, step (3) obtain and the tungsten tin rough concentrate 3 that step (4) obtains merge, add sulfuric acid solution 1000 ~ 2000g/t, the copper-bath 100 ~ 300g/t of mass concentration 5%, the butyl xanthate solution 100 ~ 200g/t of mass concentration 1% and 2# oil stoste 30 ~ 50g/t that mass concentration is 5%, sweep flotation flowsheet through a thick essence two and remove sulphide ore, obtain tungsten tin bulk concentrate;
(6) the tungsten tin bulk concentrate that step (5) obtains is roughly selected under magnetic field intensity 10000 ~ 13500Gs wet high-intensity magnetic separation condition, selectedly under 8000 ~ 10000Gs wet high-intensity magnetic separation condition realize W-Sn separation, obtain tungsten concentrate and Tin concentrate respectively.
Described coarse grain heavy mineral refers to that granularity is monomer tin tungsten mineral and the proportion > 4g/cm of+0.074mm
3rich intergrowth, particulate aggregate refers to the monomer tin tungsten mineral that granularity-0.074mm is and proportion < 4g/cm
3lean intergrowth.
Unless otherwise indicated, percentage of the present invention is mass percent, and each constituent content percentage sum is 100%.
Outstanding advantages of the present invention is:
1, jigging branch sorting technology is adopted to be divided into by material two: one to be coarse grain heavy mineral { the monomer tin tungsten mineral of granularity comparatively thick (+0.074mm) and comparatively large (the > 4g/cm of proportion
3) rich intergrowth, two is particulate aggregate { the monomer tin tungsten mineral of granularity comparatively thin (-0.074mm) and less (< 4g/cm of proportion
3) lean intergrowth.Then sort respectively two mineral, the mineral that realize having dissociated slightly receive the principle early received, and the mineral that do not dissociate process separately, ensure the tungsten tin rate of recovery.
2, effectively can reclaim the tungsten tin mine thing of the difficult choosings such as main metal content is low, mineral disseminated grain size plucked, the tight symbiosis of mineral, obtain desirable mineral processing index.
3, production and application equipment number of units is few, and production cost is low.
