Abstract
The invention relates to a lithium oxide mineral separation collecting agent and an application method thereof, in particular to a metal lithium oxide mineral separation collecting agent and a preparation method thereof, which are characterized in that the metal lithium oxide mineral separation collecting agent includes, by weight, from 40 to 55% of oxyparaffin soap, from 40 to 55% of sulfonated soap, from 10 to 20% of naphthenic acid and from 3 to 6% of active agent. The lithium oxide mineral separation collecting agent is fine in selectivity, the grade of concentration obtained by the aid of the collecting agent is higher than that of concentration obtained by the aid of an original collecting agent, the collecting agent is low-temperature-resistant and can be used for ore pulp without heating the ore pulp, when the collecting agent is used for the ore pulp at the temperature ranging from 11 DEG C to 15 DEG C, recycling rate of the collecting agent is increased about 6.5% as compared with the original collecting agent, and accordingly the collecting agent is low-temperature-resistant. Mineral separation cost can be greatly reduced, and the lithium oxide mineral separation collecting agent can be more widely applicable to raw ores with high argillization degree.
Description
Technical field
A kind of lithia mineral beneficiation collecting agent and using method, particularly a kind of collecting agent for the ore dressing of burning lithium minerals and preparation method thereof.
Background technology
The collecting agent that current domestic lithia ore deposit Mineral Processing Industry uses is mainly the series products taking oxidized paraffin wax soap and sulfonation soap as primary raw material, there is poor selectivity in such collecting agent, not low temperature resistant, to sludge sensitivity, the shortcomings such as concentrate grade is low, in ore dressing process, need ore pulp to carry out heat treated, power consumption is large, cost is high.And the current lithium mineral resources overwhelming majority is in the area of high height above sea level low temperature, lean ore is many, rich ore is few, difficult ore dressing is many, for ore-dressing technique has increased difficulty, not former collecting agent not low temperature resistant and just particularly outstanding to the sensitivity of sludge, cause lithium concentrate grade low, production process is unstable, and these difficult points make it be badly in need of at present a kind of can application in the invention of cryogenic conditions and selective good lithium ore deposit collecting agent.
Summary of the invention
Object of the present invention is exactly the deficiency existing for above-mentioned prior art, provides a kind of low temperature resistant, selectively good, to sludge insensitive lithia mineral beneficiation collecting agent and using method thereof.
The object of the invention is to be achieved through the following technical solutions.
A kind of lithia mineral beneficiation collecting agent, is characterized in that its components by weight percent comprises oxidized paraffin wax soap 40% ~ 55%, sulfonation soap 40% ~ 55%, aphthenic acids 10% ~ 20%, activating agent 3% ~ 6%.
A kind of lithia mineral beneficiation collecting agent of the present invention, is characterized in that described activating agent is a kind of or two or more in dodecyl sodium sulfate, sodium cetanesulfonate, DTAC.
The using method of a kind of lithia mineral beneficiation collecting agent of the present invention, it is characterized in that use procedure mixes in proportion oxidized paraffin wax soap, sulfonation soap, aphthenic acids and activating agent, add again water to stir evenly, then after heating, add again sodium hydroxide solution to be saponified into paste, be used further to ore dressing process.
The using method of a kind of lithia mineral beneficiation collecting agent of the present invention, is characterized in that its amount that adds water is 40% of oxidized paraffin wax soap, sulfonation soap, aphthenic acids and active agent intermixture total amount.
The using method of a kind of lithia mineral beneficiation collecting agent of the present invention, is characterized in that it adds the temperature heating after water is 100 ~ 130 DEG C, and the heat time is 2 hours.
The using method of a kind of lithia mineral beneficiation collecting agent of the present invention, is characterized in that its mass concentration that adds sodium hydroxide solution is 30% to carry out saponification, and saponification time is 2 hours.
A kind of lithia mineral beneficiation collecting agent of the present invention, collecting agent is selectively good, can obtain the concentrate grade higher than former collecting agent; Relatively low temperature resistant, can not heat ore pulp and use, in the time that 11 ~ 15 DEG C of slurry temperatures use, index is compared with former collecting agent, and the rate of recovery improves approximately 6.5%, and the feature that it is low temperature resistant has been described.Can greatly reduce beneficiation cost; The higher raw ore of argillization degree is had to adaptability widely.
