Method for extracting finished iron from iron ore

Abstract

The invention discloses a method for extracting finished iron from iron ore. The method comprises the working procedures of acquiring iron ore video information, sorting colors, removing impurities, carrying out dust falling, performing rough concentration of granularity of the iron ore, feeding, conveying by a conveying belt, performing magnetic separation on the finished iron and detecting the iron content, and the above procedures are sequentially arranged; a camera or a vidicon is adopted to acquire color and shape information of the tiled iron ore raw material through the iron ore video information acquisition procedure; the iron ore is sorted according to the preset color threshold value information and the preset shape threshold value information through the color sorting procedure based on the color and shape information of the tiled iron ore, acquired by the iron ore video information acquisition procedure; the magnetic separation procedure of the finished iron particularly comprises the steps of the former magnetic separation, the later magnetic separation and the final fine magnetic separation. The method for extracting finished iron from iron ore has the advantages of low resource consumption, high working efficiency and good product quality.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a method for obtaining finished iron from iron ore. Background technique [0002] According to the physical and chemical properties of different minerals in the ore, after the ore is crushed and ground, gravity separation, flotation, magnetic separation, electric separation, etc. are used to separate the useful minerals from the gangue minerals, and make all kinds of symbiosis (Associated) useful minerals are separated from each other as much as possible, and harmful impurities are removed or reduced to obtain raw materials for smelting or other industries. Mineral dressing can enrich useful components in minerals, reduce fuel and transportation consumption in smelting or other processing, and enable low-grade ores to be economically utilized. The data obtained from the beneficiation test is the main basis for the evaluation of ore deposits and the design of plant constructi...
