Abstract

The invention discloses a method for separating tantalum and niobium from red mud by utilizing ultrasonic wave. The method comprises the following steps: pretreating red mud which is taken as an initial material to obtain diluted tantalum-niobium solution; and carrying out tantalum-niobium separation and extraction by taking the diluted tantalum-niobium solution as a material liquid phase and sec-octyl alcohol as an organic phase and adopting ultrasonic wave. The method effectively improves the separation conditions of tantalum and niobium minerals in micro-fine particle sludge, can effectively disperse and flocculate micro-fine sludge taking gangue mineral as a main component, is high in tantalum and niobium grade, can improve the quality of materials in subsequent operations, is extremely small in use amount of dispersing agent and flocculating agent, and is favorable for environment protection and remarkable in economical and technical benefits. By adopting the method, while realizing recovery of tantalum and niobium concentrates, enrichment of noble metal tantalum and niobium in the red mud can be further realized through acidolysis and ultrasonic treatment, so that separation and extraction of tantalum and niobium can be achieved.

Description

technical field

[0001] The invention belongs to the technical field of separation and extraction of tantalum and niobium, and in particular relates to a method for separating tantalum and niobium from red mud by ultrasonic waves. Background technique

[0002] Tantalum and niobium are two important rare metal element materials, which have important strategic and economic value. With the development of economy, the consumption of various electronic products continues to grow, which makes the industrial demand for tantalum and niobium increase sharply, which intensifies the demand for tantalum and niobium. , The tightness of the supply of niobium mineral resources. my country has abundant reserves of tantalum and niobium raw materials, of which tantalum accounts for 20% of the world's reserves, and niobium accounts for about 15% of the world's reserves. Fine, the recovery rate of beneficiation is low, especially the low recovery rate of tantalum and niobium in fine-grained ore ...
