Abstract

A flotation separation method of fluorite and dolomite in the acidic conditions comprises the steps of utilizing sulfuric acid as a pH (potential of hydrogen) adjusting agent; utilizing acid magenta and ferric citrate as an inhibitor of the dolomite and other impurity minerals; utilizing plant oleic acid as a collecting agent of a fluorite mineral. According to the flotation separation method of the fluorite and the dolomite in the acidic conditions, the fluorite mineral can be separated from the dolomite and the other impurity minerals through flotation and a fluorite concentrate can be obtained, wherein the grade of the fluorite is 97.11 to 97.75% and the recovery rate of the fluorite is 79.25 to 83.90%.

Description

A kind of under acid condition the flotation separation method of fluorite and dolomite
One, technical field
The present invention relates to fluorite and dolomite separation method, particularly a kind of under acid condition the flotation separation method of fluorite and dolomite.
Two, background technology
In the mineral deposit of fluorite and dolomite association, because dolomite and fluorite are all calcium minerals, their floatability approaches, the activity of adding magnesium ion in dolomite mineral is very strong, generally fluorite and dolomite are difficult to FLOTATION SEPARATION, because other impure mineral is as the interference of silicate mineral, the thin mud of impurity, cause its FLOTATION SEPARATION more difficult in addition; Even if idol has recovery fluorite mineral, its flotation flowsheet structure is not only complicated, make with medicament many, and production cost is high, and deficiency in economic performance, has limited the development and utilization of this class fluorite.
Three, summary of the invention
The object of the present invention is to provide a kind of under acid condition the flotation separation method of fluorite 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: a kind of under acid condition the flotation separation method of fluorite 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%, through material phase analysis, show, ore mainly, containing fluorite, dolomite, quartz and sour calcium, separately has a small amount of barite mineral.
Concrete steps and regime of agent are as follows:
(1) with sulfuric acid, adjusting slurry pH is 5~5.5,
(2) use acid fuchsin and ironic citrate as the inhibitor of dolomite and other impure mineral,
(3) with vegetable oil acid, make the collecting agent of fluorite mineral,
(4) in floatation process, after ore ore grinding to mineral monomer is dissociated, after adding sulfuric acid and adjusting slurry pH and be 5~5.5, then add acid fuchsin and ironic citrate inhibition dolomite and other impure mineral, adding vegetable oil acid carries out collecting to fluorite mineral and obtains fluorite concentrate product again
(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
