Abstract
A flotation separation method for fluorite and dolomite in acid condition, comprise the steps: to adopt sulfuric acid do pH value adjusting agent, acid fuchsin and ironic citrate as dolomite and other impure mineral inhibitor, make the collecting agent of fluorite mineral with vegetable oil acid.Adopt the present invention can make fluorite mineral and dolomite and other impure mineral FLOTATION SEPARATION, acquisition fluorite grade is 97.11% ~ 97.75%, and the rate of recovery is the fluorite concentrate of 79.25% ~ 83.90%.
Description
One, technical field
The present invention relates to fluorite and dolomite separation method, particularly the flotation separation method of a kind of fluorite in acid condition and dolomite.
Two, background technology
In the mineral deposit of fluorite and dolomite association, because dolomite and fluorite are all calcium minerals, their floatability is close, the activity of adding magnesium ion in dolomite mineral is very strong, generally fluorite and dolomite are difficult to FLOTATION SEPARATION, in addition because other impure mineral is as the interference of silicate mineral, the thin mud of impurity, cause its FLOTATION SEPARATION more difficult; Even if idol has recovery fluorite mineral, its flotation flowsheet structure is not only complicated, make with medicament many, and production cost is high, deficiency in economic performance, limits the development and utilization of this kind of fluorite.
Three, summary of the invention
The object of the present invention is to provide the flotation separation method of a kind of fluorite in acid condition and dolomite, it can improve fluorite concentrate grade and the rate of recovery.
The present invention achieves the above object by the following technical solutions: the flotation separation method of a kind of fluorite in acid condition and dolomite, in raw mineral materials used, the content of fluorite is 53.27 ~ 60.19%, quartz content is 3.67 ~ 5.62%, dolomite content is 23.90 ~ 26.20%, calcium carbonate is containing 0.95 ~ 1.30%, show through material phase analysis, ore mainly containing fluorite, dolomite, quartz and sour calcium, separately has a small amount of barite mineral.
Concrete steps and regime of agent as follows:
(1) slurry pH is adjusted to be 5 ~ 5.5 with sulfuric acid,
(2) with acid fuchsin and the ironic citrate inhibitor as dolomite and other impure mineral,
(3) collecting agent of fluorite mineral is made with vegetable oil acid,
(4) in floatation process, after being dissociated by ore ore grinding to mineral monomer, adding sulfuric acid adjustment slurry pH is after 5 ~ 5.5, then adds acid fuchsin and ironic citrate suppresses dolomite and other impure mineral, add vegetable oil acid again to carry out collecting to fluorite mineral and obtain fluorite concentrate product
(5) the total consumption of medicament is:
Sulfuric acid 2500 ~ 3500g/t
Acid fuchsin is roughly selected 200 ~ 300g/t and is scanned the selected 100 ~ 200g/t of 100 ~ 200g/t
Ironic citrate is roughly selected 1000 ~ 2000g/t and is scanned the selected 500 ~ 1000g/t of 500 ~ 1000g/t
Vegetable oil acid is roughly selected 1000 ~ 2000g/t and is scanned 500 ~ 1000g/t
During use, described medicament is first mixed with following concentration expressed in percentage by weight:
Outstanding advantages of the present invention is:
1, can make fluorite mineral and dolomite and other impure mineral FLOTATION SEPARATION, obtaining fluorite grade is 97.11% ~ 97.75%, and the rate of recovery is the fluorite concentrate of 79.25% ~ 83.90%.
2, flowage structure of the present invention is simple, and dosing is few.
