Abstract
The invention discloses an ore dressing process for removing arsenic and sulphur from bellmetal ores. According to the ore dressing process, arsenic sulfur concentrate containing copper lower than 0.8wt% is removed through a floating open circuit, copper contained in floating foam is recovered, therefore, loss of copper in sulfide can be controlled effectively, the recovery rate of copper of the bellmetal ore is increased while contents of the arsenic and the sulphur serving as impurities in the bellmetal ore are reduced remarkably, and pressure on copper melting and environment protection is relieved.
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 in stannite, sulphur.
Background technology
Arsenic, smelting and the efforts at environmental protection impact thereof of sulfur content on copper in stannite are larger, therefore tighter to the content requirement of arsenic, sulphur in stannite.For this reason, the applicant unit has just built up the arsenic removal of stannite boiling roaster, sulphur refining preprocessing system several years ago.Because ore is day by day poor, thin, assorted, difficult, select arsenic, sulphur in the stannite of factory's output to exceed standard day by day serious, the one, cause the pressure of copper smelting and efforts at environmental protection thereof increasing, the 2nd, because exceeding standard, the arsenic in stannite, sulfur content imposed a fine, affect the economic benefit of Liao Xuan factory.In order to alleviate, copper is smelted and the pressure of efforts at environmental protection, increase the economic benefit of selecting factory, stannite should be delivering before smeltery, adopt the method for ore dressing to reduce arsenic, the sulfur content in stannite as far as possible, alleviate the pressure of copper smelting and efforts at environmental protection thereof, reduce copper smelter and make the possibility to environment, reduce choosing, smelting integrated cost that copper is produced, the problem exceeding standard from source solution stannite arsenic, sulphur is significant.
Theoretically, flotation sulphide removal for stannite (arsenic, sulfur mineral) is easy, but difficulty is to control copper 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 a kind of stannite arsenic removal, sulphur ore dressing for the problems referred to above, this technique can be controlled the loss problem of copper in sulfide effectively, in improving stannite copper recovery, obviously reduce the content of arsenic impurities in stannite, sulphur, alleviated that copper is smelted and the pressure of efforts at environmental protection.
Above-mentioned purpose of the present invention realizes by following means:
1. for the stannite exceeding standard containing arsenic, sulfur-bearing, utilize flotation open circuit to remove the sulphur arsenic concentrate of cupric lower than 0.8wt%;
2. utilize gravity treatment to reclaim the copper 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 stannite obtaining after stannite arsenic removal, sulphur occurs that arsenic, sulphur exceed standard, should increase arsenic removal, sulphur flotation scan number of times to 2 time more than.
In the time of shaking table mine tailing cupric >=8%, 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 stannite, the processing of sulphur ore-dressing technique after ore grinding again.
Flotation sulphide removal for stannite (arsenic, sulfur mineral) is easy, and difficulty is to control the loss of copper in sulfide.The present invention adopts gravity treatment to reclaim the copper of carrying secretly in flotation froth, and this contradiction is resolved, and has effectively controlled the loss problem of copper 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 stannite, and its process structure is simple, easy to operate, easily realizes.Utilize the sulphur arsenic concentrate that flotation output cupric is lower, open circuit is removed most arsenic, sulfur mineral; Utilize gravity treatment to reclaim the copper of carrying secretly in flotation froth to the chats of flotation, improve the copper recovery of stannite 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 stannite as far as possible.
The method arsenic removal of ore dressing for above-mentioned high-As and high-S stannite 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 stannite 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 copper smelting and efforts at environmental protection thereof, reduce copper smelter and made the possibility to environment, reduced choosing, smelting integrated cost that copper 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.
Detailed description of the invention
Embodiment: example is below by the above-mentioned process of the present invention, processes certain batch of stannite actual effect of applicant unit.
This batch of stannite cupric 42.43%, containing arsenic 5.37%, sulfur-bearing 8.86%, belong to the high-As and high-S stannite exceeding standard containing arsenic, sulfur-bearing, after processing with stannite arsenic removal, sulphur beneficiation new process, it is 18.48% sulphur arsenic concentrate that open circuit is removed productive rate, sulphur arsenic concentrate cupric 0.758%, containing arsenic 18.67%, sulfur-bearing 31.73%, copper 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% stannite, stannite cupric 56.34%, containing arsenic 1.21%, sulfur-bearing 1.48%, copper recovery is 98.57%; Also obtain productive rate and be 7.28% the rich chats of copper, the rich chats cupric 6.41% of copper, containing arsenic 13.98%, sulfur-bearing 26.09%, copper recovery is 1.10%.
