Description
Technical field
The present invention relates to technical field of beneficiation, particularly relate to a kind of fluorite collecting agent and preparation method thereof.
Background technology
Fluorite is the important source material of fluorination industry, therefore along with the extensive development of China's fluorination industry, the need of fluorite
The amount of asking is the most unprecedented soaring.The fluorite resource of China is abundanter, but the grade of fluorite is the most on the low side, generally 35～40%, because of
This needs the method by flotation to be enriched with, so that the grade of fluorite reaches relevant industries and requires and utilized.
For a long time, the floatation process of fluorite mostly using oleic acid as collecting agent, using soda as regulator, with waterglass
As inhibitor, and this floatation process needs to carry out under the conditions of room temperature (about 25 DEG C) or heat (more than 30 DEG C).But
It is that have that collecting ability is not enough, consumption is big, resistance to low temperature is poor, foaming characteristic is weak as collecting agent using oleic acid, price etc. lacks
Point, especially under conditions of temperature is relatively low, (such as: the winter of northern area, temperature is relatively low, treats that the temperature of flotation pulp is universal
Less than 15 DEG C), treat that flotation pulp must be heated to more than 20 DEG C guarantee fluorites and has preferable flotation effect, this makes
The floatation process obtaining fluorite needs to waste bigger energy consumption.
In recent years, in order to solve the weak point using oleic acid as collecting agent, those skilled in the art proposed
The technical scheme improved, such as: Chinese patent CN103341412A discloses a kind of technology using compounding oleic acid as collecting agent
Scheme, Chinese patent CN1150065A and CN102764700A discloses the technical scheme using sulphation oleic acid as collecting agent,
Chinese patent CN101507948A discloses using polyoxyethylene ether carboxylic acid and cetyl sulfonic acid as the technical scheme of collecting agent.
Although these technical schemes to some extent solve the collecting sex chromosome mosaicism of fluorite under the conditions of low temperature (10～15 DEG C), but
That its collecting effect is the most very good, the response rate of fluorite after one roughing and obtained fluorite grade all
It not the highest；Additionally, polyoxyethylene ether carboxylic acid and cetyl sulfonic acid and compounding oleic acid based on oleic acid exploitation, sulfated oil
The medicament prices such as acid are higher, and the cost of the most existing collecting agent is the most higher.

Hour, these technical parameters both can enable sulfonating reaction fully complete, can guarantee that again this preparation method has higher life
Produce efficiency.Owing to the addition of sulfonated reagent is not to add, therefore in sulfonating reaction with unsaturated fatty acid equimolar amounts
After the most completely, sulfonated reagent is the most depleted, and part unsaturated fatty acid is sulfonated becomes sulfonation unsaturated fatty acid, its
His unsaturated fatty acid residue, therefore obtain in step A is the mixture of unsaturated fatty acid and sulfonation unsaturated fatty acid, and
And the weight accounting of sulfonation unsaturated fatty acid is about 30～40%.
(2) in step, after treating sulfonating reaction, being preferably cooled to room temperature (i.e. about 25 DEG C), this can be step B
In complex treatment provide convenient.
(3) in stepb, temperature during stirring is preferably room temperature (about 25 DEG C), and mixing time is preferably 0.5～1
Hour, these technical parameters both can make each material stir, and can guarantee that again this preparation method has higher production
Efficiency.
(4) in step C, the consumption of water at least need meet the alkali of 8-12 weight portion can be completely dissolved this want
Ask, but in view of in finished product fluorite collecting agent, the gross weight of host and auxiliary agent and the weight ratio of water preferably 1:1-10 it
Between, therefore the consumption of water is also unsuitable too much.
(5) in step C, aqueous slkali is the most slowly homogeneously added into (this adition process in compounding mixture
The time that preferably controls completed within half an hour), this can enable aqueous slkali better contact with compounding mixture, thus promotes
The compounding abundant saponification of mixture.
It should be noted that each raw material used in this preparation method is said in above-mentioned fluorite collecting agent part the most
Understanding, therefore this preparation method does not repeats.The raw material sources used due to this preparation method are very wide, and cost is the lowest, and
