Description
Technical field
The present invention relates to a kind of fluorite flotation agent, and in particular to a kind of fluorite flotation collecting agent.
Background technology
The collecting agent that domestic fluorite ore mineral processing production is mainly used is based on fatty acid, and generally using oleic acid, oleic acid is
A kind of important collecting agent of non-sulfide ore flotation, but the collecting agent exist poorly water-soluble, temperature sensitive, poor selectivity and intolerant to
The shortcomings of hard water, consumption are big, concentrate grade is low and index fluctuation is big, when being especially less than 15 DEG C with northern area water temperature in the winter time,
Need to heat ore pulp in ore dressing process, or even the long-term heating of factories and miness slurry is selected in some north, causes energy consumption and ore dressing
Cost increase, and environmental pollution is serious, economic, efficient, cleaning relatively difficult to achieve to fluorite ore resources is developed；Some efficiency
Good synthesis collecting agent such as Mei Dilan, AKK and nROX etc., because synthesis step is more, high cost, some raw materials are difficult to obtain, it is difficult to
Utilize, therefore a kind of low temperature resistant, low cost and the good collecting agent of the selective effect of collecting are badly in need of in the fluorite ore utilization of resources.
The content of the invention
The purpose of the present invention be for problems of the prior art provide a kind of low temperature resistant, good water solubility easily disperse,
The good and strong collecting ability fluorite flotation collecting agent of selectivity.
A kind of fluorite flotation collecting agent of the present invention, is mixed by the raw material of following parts by weight：4- oxygen bridge hexadecylic acids
10-30 parts, 30-60 parts of oleic acid sulphation soap, 10-35 parts of terpenic oil, 5-15 parts of OPEO.
Preferably:Fluorite flotation collecting agent, is mixed by the raw material of following parts by weight：The raw material matter
Amount part is 20 parts of 4- oxygen bridges hexadecylic acid, 45 parts of oleic acid sulphation soap, 25 parts of terpenic oil, 10 parts of OPEO.
The preparation process of the oleic acid sulphation soap is：
Using oleic acid as base stock, oleic acid quality 10%-20% concentrated sulfuric acid esterification 40~90 minutes, institute are added to it
Concentrated sulfuric acid concentration is stated not less than 88%；After esterification is finished, into reaction product, addition caustic soda is neutralized, and adjusts pH value
7.0~7.5, react 1~1.5 hour, produce oleic acid sulphation soap.
The preparation method of the fluorite flotation collecting agent of the present invention is as follows：
Terpenic oil and OPEO are added into oleic acid sulphation soap by proportioning, at room temperature stirring reaction 0.5
~1 hour, after question response are finished, 4- oxygen bridge hexadecylic acids are added into the product, mixing are stirred at room temperature 0.5~1 hour,
Produce the low-temperature type fluorite flotation collecting agent.
The 4- oxygen bridge hexadecylic acids of the present invention are one kind of ether acid, be characterized in collecting power strong, good, the more resistance to hard water of selectivity and
Low temperature, can improve the collecting performance and selectivity of the present invention, strengthen resistance to low temperature；Oleic acid sulphation soap good water solubility, it and it is molten
The low foaming agent of point is added in fatty acid molecule arrangement together, is added emulsifying dispersivity of the present invention in ore pulp, that is, is increased
Add the present invention in the coverage rate of mineral surfaces, the collecting ability of the present invention can be improved by a relatively large margin；Terpenic oil is 2# oil, is mesh
Preceding widely used foaming agent, can strengthen the frothing capacity of the present invention；OPEO, is characterized in having well
Emulsification, dispersive property, can improve the spread and collecting performance of the present invention.
The invention has the advantages that：
The fluorite flotation collecting agent of the present invention is selectively good, and collecting ability is strong, can be significantly improved under low temperature or normal temperature
Fluorite ore grade and the rate of recovery, it is adaptable to lean ore, the ore-dressing technique of difficult ore dressing, and flotation froth is stable in properties, resistance to hard water and
Low temperature, water solubility and good dispersion, dosing are greatly lowered.
