Description
Technical field
The present invention relates to a kind of carbonate-type collophane pillar collecting agent in reverse floatation, particularly a kind of collophane pillar is counter to float
The new and effective collecting agent of choosing removing carbonate mineral.Belong to the technique of preparing of collophane.
Background technology
In recent years, the pillar reverse flotation technology of carbonate type phosphate rock stone was increasingly paid close attention to by people, a part
Enterprise has started to commercial application, but because column-type floatation and conventional groove flotation have bigger difference, no mechanical forced is stirred
Mix, ratio of height to diameter is big, flotation froth is certainly excessive etc., currently without the collecting agent developed specifically designed for Collophanite flotation post reverse flotation,
And conventional groove flotation collecting agent is present that the bubble collapse time is short, bubble big, bubble and medicament it is mandatory contact, medicament and ore deposit
Thing remineralization efficacy difference etc., therefore need to study the special collecting agent of column-type floatation, to realize that half foam life period length, bubble are small, be difficult
Annex broken etc., reach reduction collector dosage, improve beneficiating efficiency, reduce the purpose of beneficiation cost.
The content of the invention
It is an object of the invention to provide a kind of carbonate-type collophane pillar collecting agent in reverse floatation, to reduce flotation collector
Consumption, improves beneficiating efficiency, reduces beneficiation cost, be it is a kind of it is economical, efficiently, the middle-low grade carbonate-type suitably promoted the use of
Collophane pillar collecting agent in reverse floatation.
The technical scheme that a kind of carbonate-type collophane pillar collecting agent in reverse floatation of the present invention is used is：
It is characterized in that whole percentage compositions are mass percent, flotation collector contains following component：
（1）Fatty acid mixed using 0.3 ~ 1 part of saturated fatty acid and 0.7 ~ 0 part of unrighted acid is raw material, control temperature
Degree slowly brings 0.5 ~ 1.5 part of SO into nitrogen in stirring condition at 30 ~ 50 DEG C from reaction unit bottom2With 0.5 ~ 1.5 part of Cl2,
In 3 ~ 4 hours reaction time, produce required raw material;
（2）By step（1）Gained raw material reacts 1 ~ 2 hour in 70 ~ 80 DEG C of temperature, addition sodium hydroxide or potassium hydroxide,
Obtain fatty acid sodium salt or sylvite；
（3）The mass percent 5 ~ 20% that a kind of methyl isobutyl carbinol accounts for fatty acid sodium salt or sylvite dry matter is added,
Produce a kind of carbonate-type collophane pillar collecting agent in reverse floatation；
（4）It is 1 that collophane pillar collecting agent in reverse floatation, which will be obtained, with water proportioning：10 ~ 200, you can for carbonate-type glue
Phosphate rock column type reverse flotation.
The beneficial effects of the invention are as follows：
1. a kind of special collecting agent in reverse floatation of carbonate-type collophane pillar.
2. compared with prior art, consumption is low.
3. beneficiation cost is low, remarkable in economical benefits.
Collecting agent, which will be obtained, is used for carbonate-type collophane pillar reverse flotation work, and existing carbonate-type collophane is counter floats
Collecting agent is selected to compare, consumption reduction by more than 30%, demagnesium rate is high, and the concentrate rate of recovery is high, and floating and enriching is high, and floating agent cost is low,
And for mill head P2O5Content is 15 ~ 18% middle-low grade carbonate-type collophane, can still obtain qualified phosphorus concentrate.
