Abstract
A low grade fluorite and barite flotation separation method uses waterglass as the inhibitor for silicious mineral and calcium carbonate mineral; uses oleic acid as the collector for fluorite and barite; and uses starch, sodium sulphate, hydrochloric acid and sodium hexametaphosphate as the inhibitor for barite mineral. The invention can perform flotation separation of low grade fluorite and barite effectively; under the condition that the given fluorite grade is 33.92%-40.41%, and the barite grade is 34.67%-35.33%, by mixing, flotation and separation, can achieves the fluorite concentrate with grade of above 95% and recovery rate of 75.5%-78.5%, and the barite concentrate with grade of 92.3%-93.27% and recovery rate of 75.2%-79.73%.
Description
One, technical field
The present invention relates to a kind of floatation separating method for mineral, particularly a kind of low grade fluorite and barite floatation separating method for mineral.
Two, background technology
Existing fluorite and barite recovery method generally is to adopt the inhibitor of waterglass as silicoide both at home and abroad, and oleic acid or enuatrol reclaim as the collecting agent of fluorite mineral; Barite then more adopts gravitational separation equipment to reclaim, and also has the method for floating of employing to reclaim.But when fluorite and barite occurred simultaneously with associated mineral, present general single recovery fluorite or barite mineral were so not only wasted resource, and have been increased the storage pressure of mine tailing; When particularly grade has only 30% left and right sides fluorite and barite to occur with the associated mineral form, do not see the report that relevant fluorite and barite reclaims simultaneously at present.
Three, summary of the invention
The object of the present invention is to provide a kind of low grade fluorite and barite flotation separation method, it can reclaim fluorite and barite simultaneously, obtains higher fluorite, barite grade and the rate of recovery.
The present invention achieves the above object by the following technical solutions: a kind of low grade fluorite and barite flotation separation method, adopt the inhibitor of waterglass as silicoide and calcium carbonate mineral, make fluorite, bar collecting agent with oleic acid, may further comprise the steps and regime of agent:
(1) slurry pH is 6～7 during flotation,
(2) with starch, sodium sulphate, hydrochloric acid and calgon medicament inhibitor as the barite mineral,
(3) in the floatation process, after adding waterglass to ore mill dissociates ore ore grinding to mineral monomer, adding oleic acid again carries out bulk flotation to fluorite, barite to the flotation device and gets bulk concentrate, the inhibitor that adds barite then suppresses barite, through 7～8 selected fluorite concentrates that get, cleaner tailings gets the barite concentrate by reverse flotation again
(4) dosing is:
Waterglass 300～400g/t
Oleic acid is roughly selected 400～500g/t and is scanned 100～200g/t
Selected 50～the 60g/t of starch
Selected 500～the 700g/t of sodium sulphate
Selected 300～the 400g/t of hydrochloric acid
Selected 300～the 350g/t of calgon.
During use, described medicament is mixed with following concentration expressed in percentage by weight earlier:
Waterglass 10～20% aqueous solution
The direct stoste of oleic acid is added
Starch 1～5% aqueous solution
Sodium sulphate 5～10% aqueous solution
Hydrochloric acid 10～20% aqueous solution
Calgon 5～10% aqueous solution
Outstanding advantage of the present invention is:
1, low-grade fluorite and barite be can reclaim simultaneously, and higher fluorite, barite grade and the rate of recovery obtained.
2, flowage structure of the present invention is simple, and dosing is few, and less energy consumption can reclaim resource comprehensive.
