Abstract
The invention belongs to a mineral processing method, and particularly relates to a mineral processing process for specially removing arsenic and sulfur in tin concentration. The mineral processing process includes steps of firstly, for the tin concentrate with overproof arsenic and sulfur content, starting with floatation for removing arsenic and sulfur concentrate with low tin content (lower than 0.8%); secondly, recycling tin contained in floatation froth by re-flotation of middlings; screening flotation tailings, and removing coarse arsenic and sulfur particles which are hard to float and are larger than or equal to 2mm on a screen. The mineral processing process can effectively control loss of tin in sulfide, recycling rate of tin in the tin concentrate is increased while content of impurities including arsenic and sulfur in the tin concentrate is obviously reduced and pressure of tin melting and environment protection affairs is alleviated.
Description
Technical field
The invention belongs to ore-dressing technique method, be specifically related to a kind of ore-dressing technique that adopts beneficiation method to remove specially arsenic, sulphur in tin concentrate.
Background technology
Arsenic, smelting and the efforts at environmental protection impact thereof of sulfur content on tin in tin concentrate are larger, therefore tighter to the content requirement of arsenic, sulphur in tin concentrate.For this reason, the applicant unit has just built up the arsenic removal of tin concentrate boiling roaster, sulphur refining preprocessing system several years ago.Because ore is day by day poor, thin, assorted, difficult, select arsenic, sulphur in the tin concentrate of factory's output to exceed standard day by day serious, the one, cause the pressure of tin smelting and efforts at environmental protection thereof increasing, the 2nd, because exceeding standard, the arsenic in tin concentrate, sulfur content imposed a fine, affect the economic benefit of Liao Xuan factory.In order to alleviate, tin is smelted and the pressure of efforts at environmental protection, increase the economic benefit of selecting factory, tin concentrate should be delivering before smeltery, adopt the method for ore dressing to reduce arsenic, the sulfur content in tin concentrate as far as possible, alleviate the pressure of tin smelting and efforts at environmental protection thereof, reduce tin smelter and make the possibility to environment, reduce choosing, smelting integrated cost that tin is produced, the problem exceeding standard from source solution tin concentrate arsenic, sulphur is significant.
Theoretically, flotation sulphide removal for tin concentrate (arsenic, sulfur mineral) is easy, but difficulty is to control tin in the loss of removing in sulfide process.Known prior art does not also have a kind of comparatively desirable method to solve this problem at present.
Summary of the invention
Object of the present invention is exactly the technique that proposes the arsenic removal of a kind of tin concentrate, sulphur ore dressing for the problems referred to above, this technique can be controlled the loss problem of tin in sulfide effectively, in improving the tin concentrate tin rate of recovery, obviously reduce the arsenic impurities in tin concentrate, the content of sulphur, alleviated the pressure of tin smelting and efforts at environmental protection thereof.
Above-mentioned purpose of the present invention realizes by following means:
1. for the tin concentrate exceeding standard containing arsenic, sulfur-bearing, utilize flotation open circuit to remove the stanniferous sulphur arsenic concentrate lower than 0.8wt%;
2. utilize gravity treatment to reclaim the tin of carrying secretly in flotation froth to the chats of flotation;
3. flotation tailing is sieved, by the more difficult emersion of flotation >=0.2mm coarse granule arsenic, sulfur mineral removes with oversize form.
Step 2. described gravity treatment is tabling.
In the time that the tin concentrate obtaining after the arsenic removal of tin concentrate, sulphur occurs that arsenic, sulphur exceed standard, should increase arsenic removal, sulphur flotation scan number of times to 2 time more than.
When shaking table mine tailing stanniferous >=8% time, increase shaking table select again number of times to 2 time more than.
Produce for the less interruption of production scale, the chats product of the oversize of screening and shaking table first should be stored up, accumulate when a certain amount of, residue enters the arsenic removal of this tin concentrate, the processing of sulphur ore-dressing technique after ore grinding again.
Flotation sulphide removal for tin concentrate (arsenic, sulfur mineral) is easy, and difficulty is to control the loss of tin in sulfide.The present invention adopts gravity treatment to reclaim the tin of carrying secretly in flotation froth, and this contradiction is resolved, and has effectively controlled the loss problem of tin in sulfide.Process characteristic of the present invention is to adopt the combined mineral dressing technology of the compositions such as flotation, gravity treatment, screening to reduce arsenic, the sulfur content in tin concentrate, and its process structure is simple, easy to operate, easily realizes.Utilize the stanniferous lower sulphur arsenic concentrate of flotation output, open circuit is removed most arsenic, sulfur mineral; Utilize gravity treatment to reclaim the tin of carrying secretly in flotation froth to the chats of flotation, improve the tin rate of recovery of tin concentrate as far as possible; The method of the mine tailing utilization screening to flotation is removed wherein coarse granule arsenic, the sulfur mineral of more difficult emersion, reduces arsenic, sulfur content in tin concentrate as far as possible.
The method arsenic removal of ore dressing for above-mentioned high-As and high-S tin concentrate of the present invention, sulphur with compared with the method arsenic removal of smelting, sulphur, adopt method arsenic removal, the sulphur of ore dressing with conventional, not only have good economic benefit, and have good social benefit.The high-As and high-S tin concentrate of using for experimental study, with 100 tons of the every processing of method of ore dressing, not only can obtain 61771 yuan of economic benefits more, can also reduce 64.26% arsenic and 66.19% sulphur and enter smelting process, greatly alleviate the pressure of tin smelting and efforts at environmental protection thereof, reduce tin smelter and made the possibility to environment, reduced choosing, smelting integrated cost that tin is produced.Beneficiation method arsenic removal, sulphur are compared with smelting process arsenic removal, sulphur, and the processing cost of beneficiation method is low, the most important thing is that beneficiation method is very little on the impact of environment.
The specific embodiment
Embodiment: example is below by the above-mentioned process of the present invention, processes certain batch of tin concentrate actual effect of applicant unit.
This batch of tin concentrate be stanniferous 42.43%, containing arsenic 5.37%, sulfur-bearing 8.86%, belong to the high-As and high-S tin concentrate exceeding standard containing arsenic, sulfur-bearing, after processing with the arsenic removal of tin concentrate, sulphur beneficiation new process, it is 18.48% sulphur arsenic concentrate that open circuit is removed productive rate, sulphur arsenic concentrate is stanniferous 0.758%, containing arsenic 18.67%, sulfur-bearing 31.73%, tin loss late is 0.33%, and arsenic removal efficiency is 64.26%, and desulphurizing ratio is 66.19%; To obtain productive rate be 74.24% tin concentrate, tin concentrate is stanniferous 56.34%, containing arsenic 1.21%, sulfur-bearing 1.48%, and the tin rate of recovery is 98.57%; Also obtain productive rate and be 7.28% the rich chats of tin, the rich chats of tin is stanniferous 6.41%, containing arsenic 13.98%, sulfur-bearing 26.09%, and the tin rate of recovery is 1.10%.
