Problems solved by technology

[0002] Most of the current mines use wet beneficiation. The process of beneficiation consumes a lot of water and electricity, and the recovery rate is up to about 85%. The efficiency is very low. The tailings formed after magnetic separation are slurry with high water content. , the treatment method is to build a tailings pond with a height of tens of meters to hundreds of meters for storage according to the site terrain. The maintenance of the tailings pond requires a lot of manpower

Example Embodiment

[0021] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0022] Such as figure 1 The wind-driven permanent magnet dry-type ore beneficiation method includes the following steps:

[0023] Step 1. Use a crocodile crusher to crush the mined raw ore to crush large ore blocks of various sizes into small ore blocks of equivalent size to form coarse ore;

[0024] Step 2. The coarse ore is transported to the double-stage hammer crusher through a conveyor belt for further crushing, and the coarse ore is crushed to a specification of less than 3mm (that is, the length, width and height of the ore are all less than 3mm) to form fine ore;

[0025] Step 3. The fine ore is transported to the cylindrical screening device through the conveying device, and the fine ore larger than 3mm is screened out and returned to step 2 for processing again. A moisture meter is installed in the screening device, and the moisture content is measured to be l...

Abstract

The invention discloses a wind driven permanent magnetic ore dressing method, which comprises the following steps: 1, coarsely crushing raw ore by jaw crushing to obtain coarse ore; 2, finely crushing the coarse ore by double-stage hammer crushing and obtaining fine ore; 3, sieving the fine ore, collecting fine ore with water content less than 3 percent for later use and drying fine ore with water content higher than 3 percent till the water content is less than 3 percent for later use; 4, performing initial magnetic dry separation on the fine ore obtained by the step 3, collecting the dryly separated magnetic fine ore for later use, and filling the tailings back to a mine; 5, grinding the dryly separated magnetic fine ore to obtain ore powder; 6, subjecting the ore powder to magnetic concentration, warehousing the concentrated magnetic metal powder, and filling the tailings back to the mine; and 7, planting trees in the refilled tailings. When the method is used, the water and power consumption is small, the recovery rate is high, the tailings are refilled directly, trees are planted in the tailings, pollution is avoided and potential collapse risks are avoided.

Description

technical field [0001] The invention relates to the field of ore dressing, in particular to a wind-force permanent magnet dry-type ore dressing method. Background technique [0002] Most of the current mines use wet beneficiation. The process of beneficiation consumes a lot of water and electricity, and the recovery rate is up to about 85%. The efficiency is very low. The tailings formed after magnetic separation are slurry with high water content. , the treatment method is to build a tailings pond with a height of tens of meters to hundreds of meters for storage according to the site terrain. The maintenance of the tailings pond requires a lot of manpower and material resources, and it is prone to landslides. In order to avoid danger, for those who have already The state strictly prohibits any modification and utilization of the tailings ponds caused by it. Therefore, wet beneficiation not only destroys the geology and environment, but also artificially causes hidden danger...
