Description
Technical field
The present invention relates to a kind of rock phosphate in powder collecting agent in reverse floatation, more particularly, to the collecting for removing calcite from rock phosphate in powder
Agent.Belong to surfactant field.
Background technology
Phosphorus ore is important strategic resource, is mainly used in and prepares phosphate and phosphate fertilizer.The production pair of phosphate and phosphate fertilizer
The requirement of rock phosphate in powder raw material is P2O5Content is 30% or more, and content of MgO is below 2%.In nature, such finger can be reached
Target rock phosphate in powder is limited, and most mid low grade phosphate rock stone needs to carry out ore dressing, to reach the requirement of high-quality rock phosphate in powder.Foam is floating
Choosing is that current sulphur dioxide of phosphor chemical industry answers a kind of ore dressing mode with the most use, wherein again with reverse flotation except the technique of dolomite is the most general
Time.The technique is only applicable to the higher phosphorite of dolomite content.There are dolomite contents in nature relatively low, calcite content
Higher Sedimentary phosphate rock.For such ore, most effective ore dressing mode is to remove calcite by reverse flotation, is made final
P in concentrate2O5Content is promoted to 30% or more.Except the collecting agent of calcite plays conclusive effect in the floatation process.Cause
This, developing a kind of rock phosphate in powder collecting agent in reverse floatation except calcite has certain application value.
Invention content
The purpose of the present invention is to provide a kind of rock phosphate in powder collecting agent in reverse floatation except calcite, for dolomite content compared with
The low and higher phosphorite of calcite content removes calcite by reverse floatation process using the collecting agent of the present invention, can will
P in concentrate2O5Content is promoted to 30% or more, has fine selectivity, the high feature of recovery rate of concentrate.
The technical scheme is that：
A kind of rock phosphate in powder collecting agent in reverse floatation except calcite, by mass percentage, by 80~90% soap agent and 10
