Embodiment Construction

[0019] In order to better understand the present invention, the content of the present invention is further illustrated below in conjunction with the examples, but the present invention is not limited to the examples.

[0020] Such as figure 1 As shown, the present invention is applied to the concentration and dehydration of tailings mixed in mine filling. The tailings slurry concentration and dehydration device includes a tailings pump pool 1, a tailings sand pump 2, a cyclone feeding pump pool 3, and a cyclone feeding pump 4. A cyclone 5, a thickener 6, and a high-concentration mixing tank 7, wherein the cyclone 5 is connected to the thickener 6 and the high-concentration mixing tank 7 respectively.

[0021] The tailings slurry produced by the concentrator after crushing, grinding and sorting is collected in the tailings pump pool 1 and sent to the cyclone feeding pump pool 3 by the tailings sand pump 2; The ore pump 4 lifts the tailings slurry to the cyclone 5 for controll...

Abstract

The invention discloses an ore pulp thickening and dewatering method and device. The ore pulp thickening and dewatering method and the device are applicable to thickening and dewatering of various types of ore pulp of mines. Pulp materials are subjected to overall classification and thickening by a cyclone, and settled sand of the cyclone directly flows to a high-concentration stirring drum, overflow of the cyclone is thickened through a thickener and sent to the high-concentration stirring drum to mix with the settled sand of the cyclone, so that satisfactory filler pulp is obtained directly.A filling process is simplified, and vicious cycle and influences of fine particle materials in the ore pulp thickening process are eliminated.

Description

technical field [0001] The invention belongs to the field of mineral processing, and in particular relates to a method for concentrating and dehydrating ore pulp, which is suitable for concentrating and dehydrating all kinds of ore pulp in mines. Background technique [0002] When underground mines use tailings for underground filling, since the concentration of tailings is very low (the low is less than 10%, and the high is only about 30%), it must be concentrated and dehydrated to achieve the required concentration for underground filling. Make the mine realize rapid backwater utilization. [0003] The traditional filling process is to use the sand pump to lift the tailings slurry produced by the concentrator to the thickener, concentrate it to about 40% underflow concentration, and then use the sand pump to lift it to the filling station into the sand bin, settle and concentrate again, and finally use When the concentration of the slurry reaches 65% or more, it is mixe...
