Abstract
The invention relates to the technical field of phosphate ore processing, in particular to a preparation method for a novel collophanite reverse flotation collector for decarbonated salt minerals. The preparation method comprises the following steps of: (1) carrying out saponification reaction on a fatty acid mixture with a carbon chain of 14-18 to obtain a fatty acid soap which is easily dissolved into water, wherein fatty acid with a carbon chain of 16-18 accounts for 70% or higher of the total fatty acid; (2) preparing a functional additive, wherein the functional additive is a mixture which takes medium-long-chain alcohol as the principal thing, and contains ester, phenol, aldehyde and part of a long-short hydrocarbon chain derivative; and (3) uniformly mixing and stirring the fatty acid soap in the step (1) with the functional additive in the step (1) in a proportion being (7-10) to 1, thereby obtaining the novel collophanite reverse flotation collector for the decarbonated salt minerals. Compared with a conventional collophanite reverse flotation collector for the decarbonated salt minerals, the collector is improved in dispersion and selectivity, and improves a froth flotation phenomenon; and control on a mineral processing production site is easy, and dose of the collector is reduced by 15% or higher.

Function additive；
3) by fatty acid soaps in step 1) and step 2) in function additive mixing and stirring；Obtain final product the glue phosphorus of decarburization acid salt mineral
Ore inverse flotation collecting agent.
Preferably, in described step 1) fatty acid mixed, the aliphatic acid for 16-18 for the carbochain accounts for total fatty acid content >=70%,
Iodine number 70-90 g/100g.
Preferably, described step 2) function additive be a kind of based on middle Long carbon chain alcohol, and containing alkane, ester, phenol, aldehyde and
The mixture of part length hydrocarbon chain derivative, its hydroxyl value: 420～450mgkoh/g.
Preferably, described step 2) function additive is including one of amylalcohol, butyl butyrate, 1,1-2 butoxy butane
Or it is several.
Preferably, described step 3) fatty acid soaps weight is 7-10 times of weight of function additive.
Preferably, 70-80 DEG C of described step 3) whipping temp, mixing speed 50-70 rev/min, mixing time 30-60 is divided
Clock.
Beneficial effects of the present invention:
1st, a kind of efficient reverse flotation of collophane removes the collecting agent of carbonate mineral, improves dispersiveness and the selection of collecting agent
Property, improves flotation froth phenomenon it is easy to mineral processing production field control；It is mainly shown as mineral processing production scene medicament dissolution
Good, lather quickness is fast, foam stability and defoaming capacity are good, to p in production2o5Grade 26.44%, the raw ore of mgo grade 3.98%
Carry out flotation, can get p2o5Grade 31.89%, the concentrate of mgo grade 0.77%, p2o5The rate of recovery 95.70%, shows the present invention's
Collecting agent product collecting ability is excellent with selective, and the abundant comprehensive utilization to phosphor resource has remarkable result.
2nd, the collecting agent simple production process that the present invention provides, product quality is stable, easily realizes industrialized production.To obtain
New decarburization acid salt mineral collophane collecting agent be used for reverse flotation work, compared with conventional Collophane anti-floatation collector,
Dispersed and selective more preferably flotation froth phenomenon is more excellent, and collector dosage reduces by more than 15%.
3rd, collector dosage of the present invention is selected to reduce by 15% than conventional collophane reverse flotation decarburization acid salt mineral collector dosage
More than, significantly reduce collophane reverse floatation agent cost；
