Description
Technical field
The present invention relates to technique of preparing field, relate in particular to a kind of fluorite collecting agent and preparation method thereof.
Background technology
Fluorite is to fluoridize industrial important source material, therefore along with China, fluoridizes the extensive development of industry, and the demand of fluorite is also unprecedented soaring.The fluorite resource of China is abundanter, but the grade of fluorite is generally on the low side, is generally 35～40%, and method that therefore need to be by flotation is its enrichment, thereby make the grade of fluorite reach relevant industries, requires and is utilized.
For a long time, the floatation process of fluorite greatly mainly with oleic acid as collecting agent, using soda ash as adjusting agent, using waterglass as inhibitor, and this floatation process need to carry out under normal temperature (25 ℃ of left and right) or (the more than 30 ℃) condition of heating.But, using oleic acid as collecting agent have that collecting ability is not enough, consumption is large, resistance to low temperature is poor, a little less than foaming characteristic, the shortcoming such as price, especially under the lower condition of temperature (for example: the winter of northern area, temperature is lower, treat that the temperature of flotation pulp is generally lower than 15 ℃), treat that flotation pulp must be heated to 20 ℃ of above guarantee fluorites and have good flotation effect, this makes the floatation process of fluorite need to waste larger energy consumption.
In recent years, in order to solve, using the weak point of oleic acid as collecting agent, those skilled in the art have proposed some improved technical schemes, for example: Chinese patent CN103341412A discloses a kind of technical scheme of composite oleic acid as collecting agent of usining, Chinese patent CN1150065A and CN102764700A disclose usings sulphation oleic acid as the technical scheme of collecting agent, and Chinese patent CN101507948A discloses usings APEO carboxylic acid and the cetyl sulfonic acid technical scheme as collecting agent.Although these technical schemes have solved the collecting problem of fluorite under low temperature (10～15 ℃) condition to a certain extent, but its collecting effect is still not very good, in the rate of recovery of fluorite after one roughing and the grade of resulting fluorite, not very high; In addition, the medicament prices such as APEO carboxylic acid and cetyl sulfonic acid and the composite oleic acid based on oleic acid exploitation, sulphation oleic acid are higher, and therefore the cost of existing collecting agent is generally higher.

(2) in steps A, after treating sulfonating reaction, be preferably cooled to normal temperature (i.e. 25 ℃ of left and right), this complex treatment can be in step B facilitates.
(3) in step B, temperature during stirring is preferably normal temperature (25 ℃ of left and right), and mixing time is preferably 0.5～1 hour, and 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 needs to meet and the alkali of 8-12 weight portion can be dissolved to this requirement completely, but consider that, in finished product fluorite collecting agent, the ratio of the gross weight of host and auxiliary agent and the weight of water is preferably between 1:1-10, so the consumption of water is also too much unsuitable.
(5) in step C, aqueous slkali preferably slowly and equably joins (preferably the control time completes this adition process within half an hour) in composite mixture, this can make aqueous slkali can contact better with composite mixture, thereby promotes the abundant saponification of composite mixture.
It should be noted that, each raw material using in this preparation method has all partly been explained at above-mentioned fluorite collecting agent, so this preparation method does not repeat.Because the raw material sources that this preparation method uses are very wide, cost is very low, and only need to synthesize, composite, these simple three steps of saponification just can make high performance fluorite collecting agent, so the fluorite collecting agent that provides of the embodiment of the present invention and preparation method thereof has good market popularization value.
