Abstract
The invention discloses a method for recycling powethite from molybdenite tailings. The method comprises the steps of adopting sodium hexametaphosphate as a tailing dispersing agent; then, classifying the tailings through adopting a high-frequency fine screen; carrying out gravity concentration on the classified tailings through adopting a shaking table to recycle powethite rough concentrate with different size fractions; and finally, mixing the powethite rough concentrate with different size fractions, grinding the powethite rough concentrate till minus 200-mesh powethite rough concentrate takes up 90%, and carrying out floatation to recycle powethite. According to the method, powethite in the tailings can be effectively recycled, and ultrafine powethite concentrate of which the molybdenum content is 32.56 to 40.37% and the recovery rate is 78.64 to 82.70% is obtained under the condition that the molybdenum content of feed ore is 0.12 to 0.17%.
Description
First, technical field
The present invention relates to a kind of recovery method of molybdenum calcium ore deposit, particularly a kind of mine tailing from molybdenite, reclaim the side of molybdenum calcium ore deposit
Method.
2nd, background technology
During some molybdenite deposit minings, usually it is associated with a small amount of molybdenum calcium mineral, due to the ore dressing side of molybdenite
Method is relatively simple, and the value adding molybdenite, considerably beyond the value of molybdenum calcium mineral, often causes while flotation molybdenite
Have ignored the value of molybdenum calcium mineral, after typically molybdenite being reclaimed abandon molybdenum calcium ore deposit in mine tailing；With molybdenum ore price by
Gradually improve, the molybdenum calcium ore deposit that some abandon in mine tailing is also provided with worth, if this part is abandoned in Tailings Dam
Molybdenum calcium ore deposit fully recycles, and positive role is played in the not only development to coloured molybdenum industry, and the development to social economy simultaneously all has
There is extremely important realistic meaning.
3rd, content of the invention
It is an object of the invention to provide a kind of method reclaiming molybdenum calcium ore deposit mine tailing from molybdenite, it can be by mine tailing
The molybdenum calcium ore deposit that grade is low, granularity is fine reclaims, and obtains higher molybdenum calcium ore deposit concentrate grade and the response rate.
The present invention employs the following technical solutions and reaches above-mentioned purpose：The side of molybdenum calcium ore deposit is reclaimed a kind of mine tailing from molybdenite
Method, is made mine tailing dispersant using sodium hexameta phosphate, is then classified mine tailing using high frequency fine screen, then the mine tailing after classification is adopted
Shaking table carry out respectively gravity treatment reclaim size fractionated molybdenum calcium ore deposit hair rough concentrate, finally again will be coarse-fine for the molybdenum calcium ore deposit hair of size fractionated
After ore deposit merges, ore grinding extremely carries out flotation recovery molybdenum calcium ore deposit again after -200 mesh account for 90%, comprises the following steps and regime of agent：
(1) mine tailing dispersant is made using sodium hexameta phosphate,
(2) be classified when positive and negative 30 microns as size fraction ranges,
(3) when adopting table concentration, 12～13 millimeters of shaking table stroke, 315～320 beats/min of jig frequency,
(4), in floatation process, after molybdenum calcium ore deposit hair rough concentrate ore grinding to -200 mesh after merging are accounted for 90%, add flotation
Groove, is subsequently adding sodium carbonate and adjusts pH9.5～10, adds acid black and makees gangue mineral inhibitor with alkalescent light green, finally adds again
Enter 18-amine. Sodium Acetate Trihydrate and vegetable oil acid makees the collecting agent of molybdenum calcium ore deposit mineral, scan triple cleaning three times through one roughing and obtain molybdenum
Calcium ore deposit concentrate,
(5) dosing is：
During use, described medicament is first configured to following concentration expressed in percentage by weight：
Unless otherwise indicated, percentage ratio of the present invention is mass percent, and each constituent content percent sum is
100%.
The present invention has the prominent advantages that：
1st, molybdenum calcium ore deposit more low-grade, that granularity is fine can be reclaimed, obtain higher molybdenum calcium ore deposit concentrate grade and the response rate.
2nd, flowage structure is simple, and dosing is few, less energy consumption, can reclaim the molybdenum calcium ore resources in molybdenite mine tailing.
