Abstract
The invention discloses a method for floating and separating zinc silicate and kutnahorite, wherein sodium carbonate is used as a pH value regulator, water glass and hydroxymethyl cellulose are used as inhibitor of manganese dolomite minerals, sodium sulphide is used as activator of zinc mineral silicates, and oxygen fossils preserved soap is used as collecting agent of the zinc mineral silicate. The method for floating and separating the zinc silicate and kutnahorite can float and separate the zinc silicate and the kutnahorite, and effectively recovers the zinc mineral silicate, and zinc concentrations having a mineral zinc content of 25.38%-26.75% and a recovery rate of 72.51%-76.44% is obtained through floatation separation under the conditions of 7.85%-10.39% of mineral zinc content.
Description
One, technical field
The present invention relates to a kind of floatation separating method for mineral, the flotation separation method of particularly a kind of zinc silicate and mangandolomite.
Two, background technology
In the FLOTATION SEPARATION process of zinc silicate mineral and mangandolomite, the floatability of mangandolomite and zinc silicate is approaching, causes its FLOTATION SEPARATION difficulty; Again since when broken, ore grinding manganese carbonate, dolomitic gangue mineral become very thin particle easily; Form a large amount of sludges, disturb the recovery of zinc silicate mineral, not only make the flotation flowsheet complex structure; Make that with medicament is many, production cost is high; Mineral processing automation is difficult to realize, causes the zinc silicate mineral rate of recovery not high, has also limited the development and utilization of zinc silicate.
Three, summary of the invention
The object of the present invention is to provide the flotation separation method of a kind of zinc silicate and mangandolomite, it can reclaim the zinc silicate mineral, obtains the higher grade and the rate of recovery.
The present invention adopts following technical scheme to achieve the above object: the flotation separation method of a kind of zinc silicate and mangandolomite; Adopt sodium carbonate do pH value adjust agent, waterglass and CMC as inhibitor, the vulcanized sodium of mangandolomite mineral do the zinc silicate mineral activator, make the collecting agent of zinc silicate mineral with oxidation paraffin wax soap, concrete steps and regime of agent are following:
(1) using during flotation sodium carbonate to transfer slurry pH is 9～10,
(2) with waterglass and CMC inhibitor as the mangandolomite mineral,
(3) make the activator of zinc silicate mineral with vulcanized sodium,
(4) in the floatation process; After ore ore grinding to mineral monomer dissociated; After adding sodium carbonate adjustment slurry pH and being 9～10, add waterglass and CMC inhibition mangandolomite mineral then, add vulcanized sodium again the zinc silicate mineral are carried out activation; The last cured soap of oxygenation fossil carries out collecting to the zinc silicate mineral and gets the zinc concentrate product
(4) the total consumption of medicament is:
Sodium carbonate 2000～4000g/t
Waterglass is roughly selected 1000～3000g/t and is scanned the selected 500～1000g/t of 300～600g/t
