Problems solved by technology

Zhou Tingxi used the flotation-magnetic separation-gravity separation process in the Dulong Tin Mine, but only part of the cassiterite above 37μm was recovered, and the cassiterite smaller than 37μm became the main factor affecting the recovery rate of cassiterite in this process. Its loss rate is as high as 26.73%

Abstract

The invention relates to a combined mineral dressing method of fine grain and micro grain cassiterite, which gives up the single mineral dressing method of fine grain and micro grain cassiterite for years. The invention adopts the effective combination of two-time flotation operation, magnetic separation operation, desliming and dewatering operation and reselection operation, provides a new mineral dressing model for selecting grain and micro grain cassiterite which has the size of 10-37 micrometers and has complex mineral property, high impurity content and big mineral dressing difficulty, and improves the cassiterite concentration ratio and cassiterite operation recovery rate; cassiterite concentration ratio can reach 5-10, the cassiterite operation recovery rate can be above 70%, and the tin-containing grade of tin concentrate products can be above 50%. The method also can be used for the mineral dressing of fine grains and micro grains of non-ferrous metal, such as tungsten, molybdenum, tantalum, niobium and the like and has favorable economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of ore dressing, and relates to a fine-grained and fine-grained cassiterite combined ore-dressing process. Background technique [0002] Tin is one of the first metals discovered and used in human history. Tin has many advantages such as low melting point, good plasticity, corrosion resistance, fatigue resistance, and non-toxicity. Tin is widely used in various fields of national economy and national defense construction. In the past, tin was widely used in the production of tinplate, solder and alloys. With the development of science and technology, the application fields of tin are expanding day by day, which leads to the increasing demand for tin in the world. With the reduction of sandy tin resources that are easy to mine and select, the level of separation of fine-grained and micro-fine-grained tin resources should be improved, and new beneficiation methods should be found. [0003] Fine-grained and ...
