Abstract

The invention discloses magnetic ore separation equipment. According to the technical point, an underflow ore discharge pipe of a magnetic separation column is connected with a feed port of a first agitating vessel, and an overflow groove ore discharge pipe of the magnetic separation column is connected with an overflow groove of a two-section magnetism flotation column; the ore discharge pipe of the first agitating vessel is connected with the feed port of a second agitating vessel, the ore discharge pipe of the second agitating vessel is connected with a feed hopper with a one-section magnetism flotation column, the one-section magnetism flotation column is connected with a scavenging device, and the overflow groove ore discharge pipe of the one-section magnetism flotation column is connected with the feeding end of the scavenging device; the two-section magnetism flotation column or a magnetic separator is used as the scavenging device, and the underflow ore discharge pipe of the two-section magnetism flotation column is connected with the feed hopper of the one-section magnetism flotation column; and the overflow groove ore discharge pipe of the two-section magnetism flotation column or a tailings discharge pipe of the magnetic separator is connected with a tailings recovery system. The invention simultaneously provides a separation method for using the equipment. Problems in the prior art that magnetic inclusion generates in the core separation of magnetite, the separation method is complicated, the floor area is large, the separation flow path is low and the separation cost is high and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of mineral separation, and relates to short-flow mineral separation equipment and a separation method, in particular to magnetic mineral column separation equipment and a method. Background technique [0002] Iron is the most commonly used metal in the world, accounting for more than 95% of total metal consumption. Due to the large-scale development of iron ore resources in my country, there is an increasing shortage of easy-to-select magnetite resources, so deep mining is required, and mining costs are gradually increasing. At present, magnetite beneficiation usually adopts continuous multi-stage magnetic separation device for separation, and finally becomes iron concentrate powder after being separated by magnetic separation column. There are also a few concentrators that use reverse flotation to separate iron concentrate powder. The flotation process has a large number of sorting stages and is complex in...
