Description
Technical field
The present invention relates to a kind of collecting agent and preparation method thereof, particularly a kind of collophane combined flotation collecting agent and its system
Method, the invention still further relates to the purposes of aforementioned collecting agent.
Background technology
Phosphorus ore is main industrial chemicals, and purposes is extremely wide, is to manufacture the products such as phosphate fertilizer, phosphate and phosphorus series additive
Main phosphorus source.China's phosphorus ore is mainly distributed on 27 provinces, autonomous regions, and wherein Hubei, Hunan, Sichuan, Guizhou and Yunnan is phosphorus
Ore deposit enrichment region, 5 provinces have found out that phosphate rock resource reserves account for the whole nation 3/4.China's phosphate rock resource is rich and not rich, state related to the world
Family compares, and China's phosphorus ore has larger difference at the aspect such as ore quality and washability.China's phosphorus ore rich ore is few, middle and low grade bauxite
Many, most phosphorus ores could meet the requirement that phosphoric acid and high-concentration phosphate compound fertilizerses produce after having to pass through beneficiation enrichment.Visiting
In bright reserves, Sedimentary phosphate rock (collophane) accounts for the 85% of China's gross reserves, and major part is middle-low grade ore, mineral
Particle is thin, and closely, objectionable impurities is many, and ore dressing difficulty is very big for embedding cloth, brings certain being stranded to the exploitation of China's phosphorus ore
Difficult.Particularly in recent years, continually develop utilization with phosphate rock resource, rich phosphorus ore and Yi Xuan phosphate rock resource increasingly reduce.Solve
The flotation of mid low grade phosphate rock, the flotation of especially middle-low grade refractory cellophane is extremely urgent.
Flotation is purification collophane main method, for the high-grade collophane easily sorting, using traditional collecting agent fat
Sour soap can get the phosphorus concentrate of high-quality with single direct flotation or reverse flotation, and the collophane for middle-low grade, due to ore
Middle gangue is complicated and content is higher, is extremely difficult to preferable flotation effect using traditional collecting agent or single flotation.Lake in 2006
Direct-reverse flotation flow process is used for the flotation of collophane by mouth of a gorge Chemical Co., Ltd. of Beijing University, achieves preferable social benefit and warp
Ji benefit, but the collecting agent that this technique direct flotation flow process is used needs hot conditions in flotation, and flotation temperature need to reach 50
The separating effect just having had more than DEG C, this makes energy consumption very big.Be rendered obvious by for current China phosphate rock resource " lean, thin,
Miscellaneous " development trend, exploitation is suitable for the collecting agent to mid-low grade collophanite ore under normal temperature or low temperature with good flotation effect
Most important.
