Problems solved by technology

The traditional method of flotation and separation of quartz potassium feldspar is hydrofluoric acid method, which is a method with relatively early application, relatively mature technology and good separation effect. This method is widely used in potassium feldspar In the field of deep processing of stone, it can effectively reduce the content of quartz in potassium feldspar concentrate. Its high efficiency has been widely recognized and promoted on a large scale in the industry. However, due to the high toxicity of HF, it will cause great pollution to the environment and damage to equipment. Corrosion is serious, and it has basically stopped using in industry

Abstract

The invention belongs to the technical field of flotation separation methods, and particularly relates to a method for flotation separation of potassium feldspar and quartz. A regulator malonic acid capable of replacing HF in a traditional hydrofluoric acid method can be found, the using effect of malonic acid is equivalent to that of HF, the requirement for the pH value in the flotation separation process is lowered, no pollution is caused to the environment, and the flotation separation process is simplified.

Description

technical field [0001] The invention belongs to the technical field of flotation methods, in particular to a method for separating potassium feldspar and quartz by flotation. Background technique [0002] Potassium feldspar is a potassium-containing framework silicate, KAlSi 3 o 8 The general term for the three homogeneous and multi-like variants of sanidine, orthoclase and microplagioclase, theoretically containing K 2 O 16.9%, SiO 2 64.7%, Al 2 o 3 18.4%. Quartz and potassium feldspar are similar in physical properties, chemical composition, and structure, so flotation has become the main method for their separation. The separation of quartz and feldspar not only becomes the key to beneficiation of silica sand, but also the basis of flotation separation of silicate minerals. [0003] Quartz and potassium feldspar both belong to the framework silicate minerals, which have the same crystal structure: silicon (aluminum) oxygen tetrahedron and four silicon oxygen tetr...
