Abstract
The invention discloses a novel mica inhibitor and a preparation method and a use method thereof. The mica inhibitor is N-methyl-9-heptadecenoic amidoethyl sodium sulfonate. The use method is as follows: (1) mica inhibitor N-methyl fatty amido acetate is prepared into aqueous solution with 5 to 10 percent of weight concentration; (2) mica ore is crushed or ground into 0.1mm to 2mm; (3) each ton of ore is added with 100g to 500g of mica inhibitor and 100g to 800g of carboxylic acid collector and uniformly mixed for 5 to 10 minutes, and deferrization operation is carried out before mica floatation. In the deferrization operation before mica floatation, the mica inhibitor is added to inhibit mica from floating up, so that the loss rate of mica is reduced. The mica recovery efficiency is increased. The mica inhibitor solves the problem that the loss rate of mica is high in the deferrization operation of floatation before mica floatation operation, the ferric mineral adsorbed on the surface of mica can be separated from the surface of mica, and during the floatation of ferric mineral, less mica is mechanically entrapped to float up.
Description
Technical field
The present invention relates to a kind of novel mica inhibiting agent and preparation method thereof and using method.
Background technology
Mica concentrate product has certain limitation to iron mineral content, and is in order to reduce iron mineral content in the mica concentrate product, generally floating except that iron mineral with the carboxylic acids collecting agent earlier before the mica flotation.
But in floatation process, because mica surface regional area elecrtonegativity is very high, and therefore many iron minerals surface lotus positive electricity or be neutral be easy to be adsorbed on mica surface, causes floatingly during except that iron mineral, and mica is carried come-up secretly, loses bigger.
As suppressing mica, then cause the back mica flotation operation rate of recovery to decline to a great extent with inhibitor such as silicate.
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 novel mica inhibiting agent and preparation method thereof and using method are provided, mica inhibiting agent of the present invention is added in deferrization operation before the mica flotation, suppresses the mica come-up, reduces the mica loss late.Improve the mica organic efficiency.It has solved the big problem of flotation deferrization operation mica loss late before the mica flotation operation, can make the iron mineral that is adsorbed on mica surface break away from mica surface, and mica can the mechanical entrapment come-up when floating except that iron mineral.
For addressing the above problem, the present invention adopts following technical scheme:
A kind of novel mica inhibiting agent of the present invention, described mica inhibiting agent are N methyl 90 seven alkene amido-ethyl sodium sulfonates; Its molecular formula is:
The present invention discloses a kind of preparation method of novel mica inhibiting agent, described step is:
The first step: generate ethylenehydrinsulfonic acid sodium with sodium hydrogensulfite and oxirane under the condition of heating, chemical reaction is as shown in the formula (1);
Second step: generate N-methyltaurine sodium with methylamine and ethylenehydrinsulfonic acid sodium under the condition of pressurization of heating, chemical reaction is as shown in the formula (2);
The 3rd step: carry out condensation reaction with oleoyl chloride and N-methyltaurine sodium and generate N methyl 90 seven alkene amido-ethyl sodium sulfonates, chemical reaction is as shown in the formula (3);
The present invention discloses a kind of using method of described novel mica inhibiting agent, comprise the following steps:
(1) outfit of the mica inhibiting agent aqueous solution: it is 5～10% the aqueous solution that mica inhibiting agent N methyl 90 seven alkene amido-ethyl sodium sulfonates are made into weight concentration;
(2) ore treatment: with mica ore reduction or ore grinding to 0.1-2mm;
