Problems solved by technology

It is precisely because of these characteristics that the amine collectors are limited in the flotation of fine-grained minerals, which is manifested in the serious entrainment of fine-grained gangue minerals in the flotation foam. The release effect is not ideal
Therefore, in the flotation of rubidium-containing fine-grained mica, it is difficult to improve the rubidium-containing grade of rubidium concentrate, which seriously limits the industrial application and development of rubidium resources.

Abstract

The invention discloses a combined collecting agent suitable for flotation of rubidium-containing fine-grained mica. The combined collecting agent comprises dodecylamine and sec-octyl alcohol in a weight ratio of 1: (1-2). In addition, the invention further discloses an application of the combined collecting agent suitable for flotation of the rubidium-containing fine-grained mica. The combined collecting agent is applied to the following ore samples: tuff-type rubidium-containing biotite ore and skarn-type rubidium-containing biotite ore, the particle size is smaller than or equal to 0.032 mm, the combined collecting agent is adopted for flotation, and the using amount of the combined collecting agent is 250-280 g/t according to the ore samples. The combined collecting agent has the advantages of being low in foam viscosity, good in fluidity, easy to prepare and the like, entrainment of fine-grain gangue in concentrate foam can be effectively reduced, and therefore the rubidium gradeof rubidium concentrate is improved, the cost of beneficiation reagents is reduced, and industrial application and development of rubidium resources are facilitated.

Description

technical field [0001] The invention relates to the technical field of beneficiation and flotation, in particular to a flotation collector suitable for rubidium-containing fine-grained mica and its application. Background technique [0002] The application range of non-ferrous metal rubidium is getting wider and wider, and the demand for basic raw materials of rubidium continues to rise. Rubidium is extracted from solid minerals, mainly from rubidium-containing mica. Rubidium smelting costs are high, and the content of rubidium in smelting raw materials directly determines whether rubidium resources have industrial significance. Generally, amine collectors are used in mica flotation in the prior art, and the amine collectors have the characteristics of strong collection capacity, large foaming volume, and thick foam. It is precisely because of these characteristics that the amine collectors are limited in the flotation of fine-grained minerals, which is manifested in the s...
