Abstract
The invention discloses a method for performing floatation on mica by using oleic acid. In the method, the mica is subjected to floatation by taking the oleic acid as a collecting agent and alkylamine salt as a foaming agent when ore pulp is in a neutral or weakly alkaline state. The method comprises the following specific steps of: (1) preparing solution of oleic acid; (2) preparing solution of alkylamine; (3) treating ore; and (4) performing floatation. In the method, the mica is subjected to floatation in neutral or weakly alkaline ore pulp by taking the oleic acid as the collecting agent and the alkylamine (salt) as the foaming agent, so that the quality and recovery rate of finished ore are greatly enhanced; and mechanical entrapment of other minerals by mica recycling operation in a comprehensive recycling process of mica-containing poly-mineral can be reduced, so that the recovery rates of other minerals are enhanced.
Description
Technical field
The present invention relates to a kind of method with the oleic acid floatation on mica.
Background technology
The mica floatation process has two kinds at present: a kind of is under acid ore pulp condition, uses the alkylamine salt floatation on mica, and this is traditional process.This method is had relatively high expectations (equipment must anti-strong acid corrosion) to equipment, and also very severe of working environment, and safety and environmental protection all are difficult to reach relevant national standard.Another kind is under neutrality or alkalescent ore pulp condition, and with alkylamine or with alkylamine and naphthenic soap associating collecting mica, this is a method commonly used at present.The relatively environmental protection of this method, not high to the equipment requirement yet, but the mica concentrate product quality and the mica rate of recovery are all not as good as conventional method.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, a kind of method with the oleic acid floatation on mica is provided, and it makes collecting agent with oleic acid, is foaming agent with alkylamine (salt), make mica flotation in neutrality or alkalescent ore pulp, the concentrate quality and the rate of recovery all significantly improve; In the comprehensive removal process of micaceous many mineral, can reduce mica and reclaim the mechanical entrapment of operation other mineral, improve other mineral recovery rate.
For addressing the above problem, the present invention adopts following technical scheme:
A kind of method with the oleic acid floatation on mica of the present invention, described method is under ore pulp neutrality or alkalescent state, makes collecting agent with oleic acid, is foaming agent with the alkylamine salt, floatation on mica.
The concrete grammar step is:
(1), the preparation of oleic acid solutions: with oleic acid and sodium carbonate is that to be made into weight concentration after 1: 1 ratio is mixed be 1～5% the aqueous solution or directly to be made into weight concentration with enuatrol be 1～5% the aqueous solution by weight, oleic acid solutions;
(2), the preparation of alkylamine solution: with lauryl amine or octadecylamine or mixed amine and hydrochloric acid is that to be made into weight concentration after 1: 1 ratio is mixed be 0.5～2% the aqueous solution by weight, alkylamine solution;
(3), ore treatment: with mica ore reduction or ore grinding to 0.1-2mm;
(4), flotation: ore per ton adds the oleic acid solutions of 100-500g and the alkylamine solution of 10-80g, stirs floatation on mica.
Described mica ore is mica concentrate ore or micaceous multimineral ore.
Traditional theory and practice think that mica generally speaking can not be by the oleic acid collecting.In fact this is understanding mistaken ideas.Mica surface is not only electronegative under the ore pulp neutral state, and also positively charged of regional area, and the positive electricity zone is easy to absorb the oleic acid radical ion; And the electronegative regional elecrtonegativity of mica surface is very high, and the particulate of the positively charged in the environment also is easy to be adsorbed on its surface, thereby is beneficial to the oleic acid collecting.But under the ore pulp neutral state, the foamability of oleic acid own very a little less than, anion foaming agent commonly used can not stick to the mica particles surface, has only with the normal barbotage of cation foaming agent (as alkylamine) competence exertion.
Test shows that the present invention makes collecting agent with oleic acid under ore pulp neutrality or alkalescent state, is foaming agent with alkylamine (salt), and the mica quality and the rate of recovery all are higher than existing two kinds of processes.
Beneficial effect of the present invention has:
1, with under neutrality or alkalescent ore pulp condition, compare with naphthenic soap associating collecting mica method with alkylamine or with alkylamine, the rate of recovery improves 5-20%, and the concentrate mica content improves 5～20%; Other valuable mineral mechanical entrapment rate decline 5-20% during comprehensive the recovery; The reagent consumption cost is constant substantially.
2, with under acid ore pulp condition compare with the alkylamine salt floatation on mica, the mica concentrate quality and the rate of recovery slightly improve, and equipment and facility can not be subjected to the strong acid corrosion, and operating environment also is greatly improved, and environmental pollution significantly reduces.
