Abstract
The invention provides a preparation method of an inhibitor of limonite. The method comprises the steps that (1) sodium carbonate, sodium hydroxide and water are mixed according to the mass ratio of 2-3:3-5:5-8, so that a solution 1 is obtained; (2) direct green dye or direct black dye is added into the solution 1 according to the mass ratio of 1-2:8-15 and stirred to be dissolved, so that a solution 2 is obtained; (3) sodium lignin sulfonate is added into the solution 2 according to the mass ratio of 1-3:8-12, the temperature of the solution 2 is controlled to range from 80 DEG C to 90 DEG C, and the mixture is stirred for reaction lasting 5 h-6 h, so that a solution 3 is obtained; (4) the solution 3 is subjected to suction filtration and washing, so that a crystalline viscous material is obtained; (5) the crystalline viscous material is dried at 70 DEG C to 80 DEG C, so that the inhibitor of the limonite is obtained. By adopting the method, the limonite can be inhibited, and the grade and recovery rate of zinc concentrate can be increased.
Description
One, technical field
The present invention relates to a kind of preparation method of inhibitor of limonite, particularly in zinc oxide and limonite FLOTATION SEPARATION process, the inhibitor of zinc oxide concentrate grade need be improved.
Two, background technology
In the removal process of zinc oxide ore, general adopt flotation to reclaim, and affect recovery index depend primarily on the impurity content such as limonite in ore, thin mud number; In FLOTATION SEPARATION process, the impurity such as limonite and thin mud and zinc oxide ore floatability close, again due to when broken, ore grinding the impure mineral such as limonite easily become very thin particle, add other disturbing factor, cause its FLOTATION SEPARATION difficulty, want to reclaim this kind of Zinc oxide minerals, not only make flotation flowsheet complex structure, make that with medicament is many, production cost is high, and recovery rate of zinc oxide is not high, limits the development and utilization of zinc mineral.
Three, summary of the invention
The object of the present invention is to provide a kind of preparation method of limonite inhibitor, the inhibitor be prepared into can suppress the limonite in zinc oxide, improves zinc oxide concentrate grade and the rate of recovery.
The present invention achieves the above object by the following technical solutions: a kind of preparation method of limonite inhibitor, comprises the steps:
(1) by sodium carbonate, NaOH and water sodium carbonate in mass ratio: NaOH: water=2 ~ 3:3 ~ 5:5 ~ 8 are mixed to get solution 1;
(2) by dyestuff direct green or directly in mass ratio black=1 ~ 2:8 ~ 15 add in solution 1, be stirred to and dissolve to obtain solution 2;
(3) add in solution 2 by sodium lignin sulfonate in mass ratio=1 ~ 3:8 ~ 12, controlling solution 2 temperature is 80 ~ 90 DEG C, and stirring reaction keeps 5 ~ 6h to obtain solution 3;
(4) by solution 3 suction filtration, wash to obtain crystalloid dope;
(5) finally that crystalloid dope is dry under 70 ~ 80 DEG C of conditions, namely obtain described limonite inhibitor.
The application of described limonite inhibitor in zinc oxide and limonite FLOTATION SEPARATION, during flotation, NaOH regulates slurry pH to be 9.5 ~ 108.5; In floatation process, after being dissociated by ore ore grinding to mineral monomer, add described inhibitor, activator, collecting agent, the total consumption of medicament is: 400 ~ 500g/t.
During use, described inhibitor is first mixed with the aqueous solution that mass percentage concentration is 2 ~ 5%.
Unless otherwise indicated, percentage of the present invention is mass percent, and each constituent content percentage sum is 100%.
Concrete advantage of the present invention is:
1, the limonite inhibitor adopting the present invention to be prepared into can suppress limonite, improves zinc oxide concentrate grade and the rate of recovery.
2, dosing is few.
