Embodiment Construction

[0008] Attached below figure 1 Specifically illustrate the implementation steps of the present invention:

[0009] a. Pass the pulp raw material through the slag separation screen 1 to remove the large slag, and send it into the pulp tank 2 after removing the large slag;

[0010] b. Input the pulp raw material in the pulp tank 2 into the sorting filter 4 to remove impurities through the pulp feeding pump 3;

[0011] c. The ore pulp raw material that has been removed by the sorting filter 4 is input into the sorter 5 for desliming and selection to obtain deslimed ore pulp and ore slurry. The deslimed ore slurry enters the flotation process, and the ore slurry is sent to the ore slurry tank 6 ;

[0012] d, the ore slurry in the ore slurry tank 6 enters the dewatering filter 8 through the ore slurry feed pump 7 to remove impurities, and the ore slurry enters the dehydrator 9 after the dewatering filter 8 removes impurities to concentrate and dehydrate, so as to obtain concentra...

Abstract

The invention provides a process for ore pulp desliming and ore slurry dehydration, which relates to a mineral processing process. The process comprises the steps of: a, removing large dreg of ore pulp raw materials by using a dreg separation sieve; b, removing impurities of the ore pulp raw materials without the large dreg by adopting a sorting filter and enabling the ore pulp raw materials to enter a sorting machine to be subjected to desliming and selection to obtain deslimed ore pulp and ore slurry; c, enabling the deslimed ore pulp to enter a floating selection procedure; after removing the impurities of the ore slurry with a dehydrating filter, enabling the ore slurry to enter a dehydrating machine to be concentrated and dehydrated so as to obtain concentrated ore slurry and reusable process pure water. The process is simple and reliable; the concentration and the grade of the ore slurry are improved and the desliming is complete; rapid concentration and dehydration of the ore slurry are realized; the process has important effects in the aspects of improving the stability of selection work and the grade and the recovery rate of ore concentrates, reducing the use amounts of a floating selection medicament and pure water and the like.

Description

technical field [0001] The invention relates to a beneficiation process, in particular to a process for desliming of ore pulp and dewatering of ore slime. Background technique [0002] Ore slime in mineral processing terms generally refers to materials with a particle size of <10um. According to the current level of mineral processing technology, it is difficult to effectively recover the particle size of <10um in the selected materials, and it will greatly interfere with the separation process, affecting the taste and quality of the concentrate. Recovery rate, increase potion consumption. Therefore, for materials with high mud content, the slime should be removed in advance according to the process needs. At present, two kinds of equipment are mainly used for desliming, such as desliming bucket or hydrocyclone, but the desliming efficiency is low, and the selected materials High mud content and high loss rate of target minerals are not conducive to the improvement of...
