Problems solved by technology

[0003] The dominant collectors in the tantalum-niobium ore flotation process are xanthate, cyanide, phosphate, xanthate, black drug ester, xanthate and other flotation agents, but in actual beneficiation, the results Many can not meet the design requirements, tantalum and niobium concentrate products contain tantalum and niobium exceeding the standard, the grade of tantalum and niobium concentrate is low, and the recovery rate of concentrate is low, resulting in a waste of mineral resources

Abstract

A beneficiation agent for tantalum-niobium ore flotation tantalum-niobium, made of the following raw materials in parts by weight: diesel oil 10-15, sodium carbonate 15-40, sodium acetate 20-30, ammonium chloride 15-25, 2-methyl Butyric acid 12‑18, quicklime 1‑2, p-benzylamine 30‑60, activator 4‑5, phenylethyl alcohol 20‑35. The invention has the characteristics of high sorting efficiency, high yield, less consumption, simple and reliable technological process, easy operation and the like, and is suitable for the application of tantalum-niobium ore flotation.

Description

technical field [0001] The invention relates to the technical field of beneficiation, and more particularly, to a beneficiation agent for flotation of tantalum-niobium ore and a preparation method thereof. Background technique [0002] At present, my country's tantalum and niobium metal raw materials are mainly niobium iron ore, tantalite, niobium iron rutile ore, tantalum rutile ore and so on. Flotation method is one of the beneficiation methods of tantalum-niobium ore. Sometimes, in order to improve the quality of tantalum-niobium concentrate and remove impurities, the tantalum-niobium concentrate is chemically processed before flotation. [0003] The dominant collectors in the flotation process of tantalum-niobium ore are xanthate, cyanide, phosphate, xanthate, black medicine ester, xanthate and other flotation reagents, but in actual beneficiation, the results Most of them fail to meet the design requirements. The tantalum and niobium concentrate products contain excess...
