Abstract
The invention discloses a method for floating and separating calamine and quartz, wherein water glass and zinc sulfate are added into a grinder to grind ores into mineral monomers and to be dissociated, then the pH of ore pulp is adjusted to the range of 10-11 by adding lime, then the calamine and carbonate minerals are floated by adding ether amine, flotation foams are discarded as tailings, and galmei ore concentrate is obtained in a flotation slot through 2-3 times of floatation. The method for floating and separating the calamine and the quartz through flotation can effectively separate the calamine and carbonate gangue minerals through flotation, and the galmei ore concentrate having a mineral zinc content of 21.26%-23.80% and a recovery rate of 72.51%-75.67% is obtained through 2-3 times of floatation separation under the conditions of 11.92%-14.10% of mineral zinc content.
Description
One, technical field
The present invention relates to a kind of floatation separating method for mineral, particularly the flotation separation method of a kind of smithsonite and quartz.
Two, background technology
In smithsonite and quartz and the separation process of carbonate gangue mineral floating, because smithsonite is approaching with quartzy floatability, owing to carbonate mineral in fragmentation, grinding process is easy to form the flotation performance that sludge influences smithsonite, cause smithsonite to be difficult to separate with quartz and carbonate gangue mineral again; Can be with its FLOTATION SEPARATION even idol has, process structure complexity not only, medicament kind and consumption are many, production cost is high, and mineral processing index is not high, so also limited the development and utilization of smithsonite.
Three, summary of the invention
The object of the present invention is to provide the flotation separation method of a kind of smithsonite and quartz, it can reclaim smithsonite, makes smithsonite obtain higher 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 smithsonite and quartz, adopt waterglass and zinc sulfate as the inhibitor of smithsonite, make pH with lime and adjust agent, make the collecting agent of quartz and carbonate gangue mineral with ether amine, concrete steps and regime of agent are as follows:
(1) slurry pH is 10～11 during flotation,
(2) with zinc sulfate and the waterglass inhibitor as smithsonite,
(3) make the collecting agent of quartz and carbonate gangue mineral with ether amine,
(4) in the floatation process, waterglass and zinc sulfate are joined after ore mill is milled to ore mineral monomer and dissociates, adding lime adjusting slurry pH again is 10～11, add ether amine then quartz and carbonate mineral are carried out flotation, flotation froth abandons as mine tailing, through 2～3 flotation, be the smithsonite concentrate in the flotation cell
(5) dosing is:
During use, described medicament is mixed with following concentration expressed in percentage by weight earlier:
Smithsonite of the present invention is zinc silicate or the zinc hydroxide mineral that contain the crystallization water.
Outstanding advantage of the present invention is:
1, smithsonite can be separated with quartz and carbonate gangue mineral floating, obtaining zinc content is 21.26～23.80%, and the rate of recovery reaches 72.51～75.67% smithsonite concentrate.
2, flowage structure of the present invention is simple, and dosing is few, and less energy consumption can reclaim resource comprehensive.
