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 method for making thereof, 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 the main phosphorus source of manufacturing the products such as phosphate fertilizer, phosphate and phosphorus series additive.China's phosphorus ore is mainly distributed in 27 provinces, autonomous region, and wherein Hubei, Hunan, Sichuan, Guizhou and Yunnan are phosphorus ore enrichment regions, and 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, compares with world's concerned countries, and China's phosphorus ore has larger difference at aspects such as ore quality and washabilitys.China's phosphorus ore rich ore is few, and middle low-grade ore is many, and most phosphorus ores must could meet the requirement of phosphoric acid and high-concentration phosphate compound fertilizers production after beneficiation enrichment.In explored reserves, appositional pattern phosphorite (collophane) accounts for 85% of China's gross reserves, and major part is middle poor value, mineral grain is thin, and embedding cloth is tight, and objectionable impurities is many, ore dressing difficulty is very large, has brought certain difficulty to the exploitation of China's phosphorus ore.Particularly in recent years, along with the utilization of continually developing of phosphate rock resource, rich phosphorus ore and Yi Xuan phosphate rock resource reduce day by day.Solve the flotation of mid low grade phosphate rock, especially middle low-grade refractory selects the flotation of collophane extremely urgent.
Flotation is purification collophane main method, for the high-grade collophane easily sorting, use traditional collecting agent fatty acid soaps can obtain high-quality phosphorus concentrate with single direct flotation or reverse flotation, and in low-grade collophane, because gangue complexity and content in ore are higher, adopt traditional collecting agent or single flotation to be difficult to the flotation effect that reaches desirable.Hubei in 2006 large mouth of a gorge Chemical Co., Ltd. is the flotation for collophane by n-reverse flotation flowsheet, obtained good Social benefit and economic benefit, but the collecting agent that this technique direct flotation flow process is used needs hot conditions when flotation, flotation temperature need reach 50 ℃ of separating effects that just had above, and this makes energy consumption very large.The development trend that obviously presents " poor, thin, assorted " for current China phosphate rock resource, it is most important that exploitation is suitable under normal temperature or low temperature the mid-low grade collophanite ore to have the collecting agent of good flotation effect.
Summary of the invention
