Problems solved by technology

[0003] At present, low-grade apatite is mostly flotation with relatively cheap fatty acid collectors, but such collectors have poor selectivity, poor low temperature resistance, and unsatisfactory flotation results.
Especially when the temperature is low, the beneficiation plant cannot produce normally, and the chemical activity can only be improved by means of heating, which increases the beneficiation cost

Abstract

The invention relates to an apatite low-temperature flotation collector and a preparation method thereof. The apatite low-temperature flotation collector comprises the following components in parts byweight: 35-55 parts of oxidized paraffin soap, 20-40 parts of soybean oil fatty acid soap and 20-30 parts of sodium fatty acid methyl ester sulfonate. The apatite low-temperature flotation collectordisclosed by the invention can realize effective flotation under the low-temperature condition of 5 DEG C. The apatite low-temperature flotation collector has good biodegradability, and can keep the COD content (less than or equal to 50 mg / L) in flotation tailing water at a low level.

Description

technical field [0001] The invention relates to the technical field of flotation, in particular to an apatite low-temperature flotation collector and a preparation method thereof. Background technique [0002] North my country is rich in low-grade phosphate rock resources and large-scale deposits, mainly concentrated in Chengde, Hebei, Chaoyang, Liaoning and Xinjiang. The useful minerals in the ore are mainly magnetite and apatite, accompanied by sulfur, cobalt, titanium, vanadium and other minerals. Although the content of apatite is relatively low, it is easy to sort and the beneficiation process is simple. The comprehensive recovery of phosphorus can not only save limited phosphorus resources, but also facilitate the comprehensive recovery of other associated useful components such as Ti, V, S, Co, etc., which is of great significance. Whether the low-grade phosphorus resources can be economically and effectively recovered depends on the performance and cost of collecto...
