Problems solved by technology

[0005] The physical method has disadvantages such as large production site occupation area, low productivity, and increased water consumption due to low concentration of the suspension; the flotation method needs to consume a large amount of reagents during the treatment process, and the chemical reagents and carrier minerals remaining in the ore are harmful to the final product. The product has adverse effects; the microbial oxidation method occupies a large area, the treatment cycle is long, and the efficiency of the fungus treatment of different types of ores is not the same, which needs further research and optimization

Abstract

The invention provides an efficient and pollution-free brightening agent used for ores. The brightening agent is prepared from the following raw materials in parts by weight: 1-20 parts of amino acid, 1-25 parts of ethylenediamine tetraacetic acid and 100 parts of water. The brightening agent and an application technology thereof provided by the invention have the advantages that brightness of ores can be improved and can be kept for a long time, namely the ores still have excellent brightness even after being kept for a period of time in a severe environment.

Description

technical field [0001] The present invention relates to an ore whitening agent, and more to a high-efficiency, non-polluting whitening agent for ore and its application process technical background [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. Generally divided into lean ore, ordinary ore and rich ore. Sometimes it is only divided into poor ore and rich ore, and there is no uniform standard for this division. [0003] In mechanical equipment, with the help of the impact and grinding action of the medium (steel ball, steel rod, gravel) and the ore itself, the particle size of the ore is further reduced until it is ground into powder. The purpose is to maximize the dissociation of the useful minerals and gangue minerals that make up the ore, so as to provide materials that meet the requirements of the next benef...
