Embodiment Construction

[0025] use Figure 1 to Figure 3A metal mineral separation flotation process of the present invention is described as follows.

[0026] Such as Figure 1 to Figure 3 Shown, a kind of metal mineral separation flotation process of the present invention, this process comprises the steps:

[0027] S1: Preliminarily crush the mined metal ore through a jaw crusher, so that the diameter of the metal ore particles is less than 1 cm, which is convenient for grinding;

[0028] S2: Put the crushed metal mineral particles in S1 into a ball mill for crushing and grinding to obtain metal mineral powder with a diameter of less than 1 mm, which is beneficial to the flotation of minerals;

[0029] S3: Put the metal mineral powder obtained in S2 into a spiral classifier to clean and classify the metal mineral powder, and then separate the magnetic substances in the metal mineral powder through a magnetic separator. The magnetic susceptibility coefficient is different to separate different mi...

Abstract

The invention belongs to the technical field of pulp floatation, in particular to a metal mineral separation flotation process. The process comprises the following steps: mined metal ores are primarily crushed through a jaw crusher, so that metal ore particles are smaller than 1 cm; the crushed metal ore particles are fed in a ball mill for crushing and grinding until metal ore powder with diameters of smaller than 1 mm is obtained; the metal ore powder is fed in a spiral grader for cleaning and classification; then, magnetic substances in the metal ore powder are separated by a magnetic separator; the separated metal ore powder is fed in a metal ore separation flotation machine; medicaments of sodium alkyl dithiocarbonate and pine oil are charged in pulp in the metal ore separation flotation machine; and meanwhile, a proper amount of sodium bicarbonate and acetic acid are fed in the pulp. Through reaction between the sodium bicarbonate and the acetic acid, a lot of bubbles can be generated, so that minerals can be fully captured, and the pulp flotation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pulp flotation, in particular to a metal mineral separation flotation process. Background technique [0002] Among the metal and non-metal separation methods, the flotation method accounts for about 70%, and most of the mineral processing plants will have flotation operations, so the flotation machine is the most commonly used mineral processing equipment. In the flotation machine, the slurry treated with chemicals is agitated and aerated, so that some of the ore particles are selectively fixed on the air bubbles; when they float to the surface of the slurry, they are scraped off to form foam products, and the rest remain in the slurry. In order to achieve the purpose of separating minerals. The flotation machine process, also known as flotation beneficiation, refers to the process of separating mineral particles by using the physical and chemical properties of the mineral surface, and is the most widely...
