Single-groove inflation stirring type flotation machine

Abstract

The invention relates to a single-groove inflation stirring type flotation machine and belongs to the technical field of mining machines. The single-groove inflation stirring type flotation machine is composed of a foam scraper blade transmission device (2), a head foam scraper blade (3), a main shaft mechanism (4), a transmission device (6) and groove bodies (17). Air is supplied through an outer air blower, and the air inflating volume of the outer air blower can be adjusted through a valve according to flotation needs; due to the fact that an impeller only performs the function of stirring and does not perform the function of air suction, the rotating speed is low, stirring is not strong, and the argillization phenomenon is not likely to happen when floatation is conducted on fragile objects. The ore pulp surface is stable, a stable foam layer can be easily formed, and thus the grading index can be easily increased; the single-groove inflation stirring type flotation machine is used for separating nonferrous metal, black metal, precious metal and non-metallic minerals, used for rougher flotation, scavenging flotation and fine flotation of chemical materials and used for recycling useful minerals. The single-groove inflation stirring type flotation machine is large in air suction volume, low in power consumption, small in equipment occupied area, convenient to maintain, capable of completely achieving automatic mechanical production, wide in application range and long in service life.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a single-tank aeration-stirring flotation machine. Background technique [0002] Ore often contains several useful components (for example, gold ore contains silver, copper, sulfur, etc. in addition to gold). concentrates. Therefore, it is possible to make full use of the useful components in complex polymetallic ores only after beneficiation. In addition to the useful components, the ore often contains impurities that are harmful to the further processing of the useful components. During the smelting process, harmful impurities enter the metal, which will seriously affect the quality of the product, and sometimes complicate the smelting process and even make it difficult to carry out. For example, the harmful impurities in copper and lead concentrates are zinc; the harmful impurities in zinc concentrates are iron; the harmful impurities in iron concentrate...

AI Technical Summary

Problems solved by technology

For example, the gold content of gold ore ranges from 2 to 10 grams per ton, the copper content of copper ore is only 0.5 to 1.0%, and the iron content of iron ore is only 20 to 30%. Direct smelting of such ores is not only technically difficult, but also Economically unreasonable, and when the ore grade is very low, it cannot be smelted at all
