Description
Technical field
The present invention relates to one kind being used for middle low temperature phosphate rock floating combination medicament and its application method, belongs to mineral floating medicament
Field.
Background technology
Phosphorus ore is applied to agricultural mainly for the manufacture of phosphate fertilizer, is partly used to produce yellow phosphorus, red phosphorus, phosphoric acid and phosphate chemical combination
Object etc..China's phosphate rock resource large storage capacity, distribution Relatively centralized, but ore, based on middle-low grade Sedimentary phosphate rock, rich ore provides
Source is few and selecting difficulty is larger.Phosphorus ore has become important one of the strategic resources in China as non-renewable resources, rationally opens
Hair is particularly necessary using domestic existing phosphate rock resource.Flotation be difficulty select phosphorus ore most ideal and it is effective sort means, with
The continuous deep people of research, floatation process technology has tended to be ripe, therefore is sorted for China's middle-low grade refractory cellophane,
The research and development of the most efficient flotation reagents become the heat subject to study now.
China's mid-low grade collophanite ore ore composition is complex, disseminated grain size is thin, if making valuable mineral monomer dissociation
Necessary fine grinding, but fine grinding certainly will lead to ore pulp argillization, to deteriorate floatation process.Valuable mineral particle surface physico-chemical property is uneven
Even property, there are active regions on its surface for different floating agents, contribute to target minreal adsorpting formulation and make surface-hydrophobicized.And
And phosphate rock floating is more sensitive to temperature, common fatty acid collecting agent dissolubility in low temperature is poor, leads to flotation effect not
It is good.The activity that can improve medicament to a certain extent under cryogenic is applied in combination in floating agent, so as to improve separating effect.
Invention content
The present invention is directed to the problem of existing phosphorite flotation collector lower temperature resistance difference, provides a kind of middle low temperature phosphate rock floating
Combination medicament can improve the activity of medicament, and form complex, down for ore to a certain extent under cryogenic
The thinner collophane of cloth granularity has preferable flotation effect.
To achieve the goals above, the invention is realized by the following technical scheme：
A kind of combination medicament for middle low temperature phosphate rock floating, the raw material and its mass percent of the combination medicament are：α-ammonia
10 ~ 50wt% of base acid, 20 ~ 60wt% of oxidized paraffin wax soap, 5 ~ 40wt% of dodecyl sodium sulfate, 5 ~ 40wt% of kerosene.
The method that combination medicament of the present invention is used for phosphate rock floating, detailed process are：First phosphorous raw ore is milled to-
0.074mm accounts for 40% ~ 80%, then adds pH regulator sodium carbonate, and additive amount is the g/t of 100g/t ~ 1000, gangue inhibitor water
Glass additive amount is the g/t of 500g/t ~ 2000, finally adds the combination medicament, and additive amount is the g/t of 20g/t ~ 300, flotation pulp
Temperature >=5 DEG C.
The present invention has the advantages that：
（1）Four kinds of medicaments used in the combination medicament are a-amino acid, oxidized paraffin wax soap, dodecyl sodium sulfate and kerosene, all
It for conventional dose, is easy to get, cheap, four kinds of medicaments are applied in combination by a certain percentage can form synergistic effect, in
There is preferable floatability to phosphorus ore under cryogenic conditions；Meanwhile collecting ability can be remarkably reinforced for independent addition,
Reach raising floatation indicators, reduce the consumption of medicament, reduces the effect of production cost.
（2）When using the combination medicament flotation phosphorus ore, there is preferable flotation effect under middle cryogenic conditions, has preferable
Dissolubility and dispersibility, medicament need not be heated, reduce energy consumption.
（3）To ore properties, complicated, down cloth fine size collophane has preferable flotation effect, production to the combination medicament
It is at low cost.
