Abstract
A kind of method of copper concentrate ore dressing, this technique selects, by utilizing the flotation open circuit removing cupric sulfur arsenic concentrate less than 0.8wt% recovery, the copper carried secretly in foam, copper loss problem in sulfide can be efficiently controlled, while improving copper concentrate copper recovery, significantly reduce the content of the arsenic impurities in copper concentrate, sulfur, alleviate the pressure of Copper making and efforts at environmental protection thereof.
Description
Technical field
The invention belongs to ore-dressing technique method, be specifically related to a kind of dresser using beneficiation method to remove arsenic in copper concentrate, sulfur specially
Skill.
Background technology
Arsenic, sulfur content in copper concentrate are relatively big on smelting and the efforts at environmental protection impact thereof of copper, therefore in copper concentrate contain arsenic, sulfur
Amount requires tighter.To this end, the applicant's unit has the most just built up copper concentrate boiling roaster arsenic removal, sulfur refining preprocessing system.
Owing to Ore is the leanest, thin, miscellaneous, difficult, selecting arsenic in the copper concentrate of factory's output, sulfur to exceed standard day by day serious, one is to cause Copper making
And the pressure of efforts at environmental protection is increasing, two is owing to the arsenic in copper concentrate, sulfur content exceed standard and imposed a fine, and have impact on and selects factory
Economic benefit.In order to alleviate the pressure of Copper making and efforts at environmental protection thereof, increasing the economic benefit selecting factory, copper concentrate should deliver smelting
Before refinery, use the method for ore dressing to reduce the arsenic in copper concentrate, sulfur content as far as possible, alleviate the pressure of Copper making and efforts at environmental protection thereof,
Reduce the Copper making work probability to environment, reduce choosing, smelting integrated cost that copper produces, solve copper essence from source
The problem that ore deposit arsenic, sulfur exceed standard is significant.
From the point of view of theoretically, copper concentrate flotation sulphide removal (arsenic, sulfur mineral) is easy, but difficulty is that controlling copper exists
Remove the loss during sulfide.The prior art being currently known also does not has a kind of ideal method to solve this problem.
Summary of the invention
The purpose of the present invention is aiming at the problems referred to above and proposes a kind of copper concentrate arsenic removal, the technique of sulfur ore dressing, and this technique can be effectively
Control copper loss problem in sulfide, while improving copper concentrate copper recovery, hence it is evident that reduce the impurity in copper concentrate
Arsenic, the content of sulfur, alleviate the pressure of Copper making and efforts at environmental protection thereof.
The above-mentioned purpose of the present invention is realized by following means:
1. for the copper concentrate exceeded standard containing arsenic, sulfur-bearing, flotation open circuit is utilized to remove the cupric sulfur arsenic concentrate less than 0.8wt%；
2. the chats to flotation utilizes gravity treatment to reclaim the copper carried secretly in flotation froth；
3. flotation tailing is sieved, by more difficult for flotation emersion >=0.2mm coarse granule arsenic, sulfur mineral with oversize form remove.
The 2. described gravity treatment of step is tabling.
When the copper concentrate obtained after copper concentrate arsenic removal, sulfur occurs that arsenic, sulfur exceed standard, arsenic removal, the scanning time of sulfur flotation should be increased
Number is to more than 2 times.
When shaking table mine tailing cupric >=8%, increase shaking table selects number of times to more than 2 times again.
The interruption less for production scale produces, and should first be stored up by the chats product of the oversize of screening with shaking table, accumulates to one
Time quantitatively, residue enters back into the arsenic removal of this copper concentrate after ore grinding, sulfur ore-dressing technique processes.
Copper concentrate flotation sulphide removal (arsenic, sulfur mineral) is easy, and difficulty is to control copper loss in sulfide.This
Invention uses gravity treatment to reclaim the copper carried secretly in flotation froth, makes this contradiction have been resolved, has efficiently controlled copper in sulfide
Loss problem.The process characteristic of the present invention is that the combined mineral dressing technology using the compositions such as flotation, gravity treatment, screening reduces copper concentrate
In arsenic, sulfur content, its process structure is simple and convenient to operate, and easily realizes.Utilize the sulfur arsenic essence that flotation output cupric is relatively low
Ore deposit, open circuit removes the arsenic of majority, sulfur mineral；Utilize gravity treatment to reclaim the copper carried secretly in flotation froth the chats of flotation, carry as far as possible
The copper recovery of high copper concentrate；The method sieving the Tailings utilization of flotation removes the coarse granule arsenic of the most difficult emersion, sulfur mineral,
Reduce the arsenic in copper concentrate, sulfur content as far as possible.
The method arsenic removal of above-mentioned high-As and high-S copper concentrate ore dressing of the present invention, sulfur with conventional with compared with the method arsenic removal smelted, sulfur,
Use the method arsenic removal of ore dressing, sulfur, not only there is preferable economic benefit, and there is preferable social benefit.For test
The high-As and high-S copper concentrate of research, often processes 100 tons by the method for ore dressing, not only can obtain economic benefit 61771 yuan more, also
Can reduce by the arsenic of 64.26% and the sulfur of 66.19% enters smelting process, significantly reduce the pressure of Copper making and efforts at environmental protection thereof,
Decrease the Copper making work probability to environment, reduce choosing, smelting integrated cost that copper produces.Beneficiation method is removed
Arsenic, sulfur are compared with smelting process arsenic removal, sulfur, and the processing cost of beneficiation method is low, it is most important that the beneficiation method shadow to environment
Ring the least.
Detailed description of the invention
Embodiment: example below is by the above-mentioned process of the present invention, processes applicant's unit batch copper concentrate actual effect.
This batch copper concentrate cupric 42.43%, containing arsenic 5.37%, sulfur-bearing 8.86%, belong to the high-As and high-S copper exceeded standard containing arsenic, sulfur-bearing
Concentrate, after processing with copper concentrate arsenic removal, sulfur beneficiation new process, open circuit removes the sulfur arsenic concentrate that productivity is 18.48%, sulfur arsenic essence
Ore deposit cupric 0.758%, containing arsenic 18.67%, sulfur-bearing 31.73%, copper loss rate is 0.33%, and arsenic removal efficiency is 64.26%, desulphurizing ratio
It is 66.19%；Obtaining productivity is the copper concentrate of 74.24%, copper concentrate cupric 56.34%, containing arsenic 1.21%, sulfur-bearing 1.48%,
Copper recovery is 98.57%；Also obtain productivity be 7.28% copper richness chats, copper richness chats cupric 6.41%, containing arsenic 13.98%,
Sulfur-bearing 26.09%, copper recovery is 1.10%.
