Collophanite direct flotation collector, and preparation method, purposes and application method thereof

Abstract

The invention provides a cellophane direct flotation collector. The collophanite direct flotation collector comprises, by weight, 75 parts to 80 parts of fatty acid soap, 10 parts to 15 parts of fatty acid monoethanolamine and 3 parts to 8 parts of non-ionic surface active agents, and the non-ionic surface active agents are selected from one or more of octylphenol ethoxylate, nonylphenol polyeothoxylates and fatty alcohol polyoxyethylene ether. The invention further discloses a preparation method of the cellophane direct flotation collector, illegal cooking oil serves as raw materials, and the cellophane direct flotation collector is obtained after deodorization and decoloring. The collophanite direct flotation collector is good in selectivity and high in collecting capacity. According to the method, the illegal cooking oil harmful to the environment serves as the raw materials, waste is turned into wealth, the carboxylic acid derivative collector containing hydroxyl and amide polar groups is prepared, and the collector has great actual significance in development and utilization of medium and low grade collophanite.

Description

technical field [0001] The invention relates to a positive flotation collector, in particular to a glenite positive flotation collector, and also relates to a preparation method and application of the collophanite positive flotation collector. Background technique [0002] Phosphorus is an important chemical raw material in my country. With the rapid economic development, the demand for phosphorus resources is also increasing, while the resources are decreasing, especially the easy-to-select other rich ores. More than 80% of the phosphorus resources in our country belong to the medium and low-grade phosphate rocks, which requires the method of beneficiation to enrich the phosphate minerals in order to meet the raw material standards for the preparation of phosphorus products. In the flotation process, the flotation agent plays a decisive role in the technical indicators of mineral processing. At present, fatty acid collectors such as oxidized paraffin wax soap and tall oil a...

Problems solved by technology

However, this type of collector consumes a large amount, has poor selectivity, and has poor applicability to hard water and low temperature flotation.
