Embodiment 1

[0073] Such as figure 1 As shown, a method for efficient utilization of stone sawing mud, the method comprises the following steps:

[0074] 1) Screening: Stir 60kg of stone sawing mud slurry containing tin and iron evenly, and then use the grading particle size (cut-off size) as S 分 The sieve is sieved to obtain the sieved coarse particles (P0) and the sieved fine particles (P1) under the sieve, where S 分 is 0.18mm (i.e. cut-off size); wherein: the particle size of the sieved coarse particles is greater than 0.18mm, and the particle size of the sieved fine particles (P1) is less than or equal to 0.18mm;

[0075] 2) Desliming: The sieved fine particles (P1) obtained in step 1) are deslimed using a cyclone to obtain fine mud and sieved fine particles (P2) after desliming; wherein: cyclone sorting The lower limit of particle size is +0.005mm. The particle size of the screened fine particles (P2) after desliming is greater than 0.005mm, and the particle size of the fine mud is...

Embodiment 2

[0079] Repeat embodiment 1, just this method further comprises:

[0080] 4) Iron concentrate recovery: the magnetic material (W) obtained in step 3) is subjected to a weak magnetic concentration to obtain iron concentrate (W1) and remaining iron tailings respectively;

[0081] 5) Tin concentrate recovery: the iron-selected tailings obtained in step 4) are subjected to a strong magnetic separation to obtain primary tin concentrate and strong magnetic separation tailings, and then the primary tin concentrate is subjected to a shaker concentration to obtain Tin concentrate (W2) and gravity separation tailings.

Embodiment 3

[0083] Repeat embodiment 2, just step 3) strong magnetic sweeping comprises a strong magnetic sweep and secondary strong magnetic sweep, wherein a strong magnetic sweep obtains a strong magnetic sweep concentrate (i.e. magnetic material) and The remaining primary tailings materials are then subjected to secondary strong magnetic scavenging to obtain secondary strong magnetic scavenging concentrates (that is, magnetic materials) and remaining fine materials.

[0084] Among them: the wet permanent magnet semi-countercurrent magnetic separator is used for the medium magnetic rough separation, and the surface magnetic induction of the wet permanent magnet semi-countercurrent magnetic separator is 1.0T. The strong magnetic scanning adopts the medium net strong magnetic machine, and the surface magnetic induction of the medium net strong magnetic machine is 3.2T.

[0085] The whiteness of the obtained ceramic raw material can reach 65% by processing the stone material sawing mud thr...

Abstract

The invention discloses a method of using tin-and-iron-containing stone sawing mud with high efficient. The method comprises the following steps that 1 ) screening is carried out, stone sawing mud powder slurry is uniformly stirred and then screening is carried out, and screened coarse particles and screened fine particles are obtained; desliming is carried out, the obtained screened fine particles in the step 1 ) are subjected to the desliming treatment so as to obtain coarse particles and fine mud after the desliming; and 3 ) magnetic separation is carried out, the deslimed coarse particlesobtained in the step 2 ) are subjected to the magnetic separation, and magnetic materials and ceramic raw materials are obtained. According to the method, the stone sawing mud is processed through processes such as the screening, the desliming, the magnetic separation and the like, a high-whiteness ceramic raw material is recycled, the valuable metal tin and iron in the high-whiteness ceramic rawmaterial can further be recycled, so that effective utilization of waste resources and comprehensive recovery of metal resources are realized, waste of the resources is reduced, emission is reduced, and the environment is protected.

Description

technical field [0001] The invention relates to a method for utilizing tin and iron-containing stone sawn mud, in particular to a method for recycling stone sawn mud resources, and belongs to the technical field of resource recovery and useful metal utilization. Background technique [0002] With the rapid development of urbanization in our country, the demand for various building materials continues to increase, and the stone processing industry develops rapidly. During the mining and processing of stone materials, a large amount of waste rock slurry will be produced, and the particle size of these waste rock slurry is very fine. In actual production, this kind of extremely fine-grained waste rock powder slurry is discharged without treatment, which not only swallows up a lot of fertile land, resulting in reduced production and income of agricultural products, but also waste rock powder eventually flows into rivers, forming colloidal stone powder particles in the water to p...
