[0004] CN104226463A discloses a high-tin polymetallic sulfide ore beneficiation method. The minerals recovered by the method using a suspended vibrating cone disc concentrator are tin-containing sulfide ores; the ore is pre-classified by a spiral classifier and a large inclined plate thickening box for classification and concentration ; However, the coarse concentrate still needs to be concentrated on a shaking table, and the size range of the ore to be processed is 10-40μm, which is relatively narrow

Embodiment 1

[0016] The antimony-containing low-grade flotation tailings (the mass content under the 200 mesh sieve is 56.0%, the antimony-containing grade is 1.10%, and the antimony oxidation rate is 91.0%) discharged from the production of a mineral processing site is firstly treated with high-frequency The vibrating screen removes the coarse-grained material with a fineness of 200 mesh, and then the hydrocyclone removes the sludge with a fineness of 800 mesh, and finally the material flows into the DSLXZ-4000 type suspension vibrating cone concentrator. With a processing capacity of 560kg / h, a rotation frequency of 10Hz and a vibration frequency of 20Hz, a separation is performed to obtain antimony concentrate and final tailings.

[0017] The beneficiation recovery rate is 49.25%, and the grade of antimony concentrate is 15.0%.

Embodiment 2

[0019] The tailings stockpiled in the tailings pool of a certain antimony ore dressing plant (the mass content under the 200-mesh sieve is 65.0%, the antimony grade is 0.65%, and the antimony oxidation rate is 86.0%), first use a high-frequency vibrating screen Screen out the coarse-grained material on the sieve with a fineness of 200 mesh, and then remove the slime from the sieve with a fineness of 800 mesh by a hydrocyclone, and finally the material flows into the DSLXZ-4000 type suspension vibrating cone concentrator. The processing capacity of the table is 710kg / h, the rotation frequency is 10Hz, and the vibration frequency is 18Hz, and a separation is performed to obtain antimony concentrate and final tailings.

[0020] The beneficiation recovery rate is 47.65%, and the grade of antimony concentrate is 20.0%.

Embodiment 3

[0022] The tailings discharged from a flotation plant of antimony sulfide ore (the mass content under the 200-mesh sieve is 62.0%, the antimony grade is 0.30%, and the antimony oxidation rate is 88.0%) is first screened out with a high-frequency vibrating screen Coarse-grained materials with a fineness of 200 mesh on the sieve, and then the hydrocyclone removes the slime of the sieve with a fineness of 800 mesh, and finally the material flows into the DSLXZ-4000 type suspension vibrating cone concentrator, and is processed in each machine. The amount is 690kg / h, the rotation frequency is 10Hz, and the vibration frequency is 18Hz, and a separation is carried out to obtain antimony concentrate and final tailings.

[0023] The beneficiation recovery rate is 43.65%, and the grade of antimony concentrate is 18.0%.

Abstract

The invention provides a method for gravity separation of fine antimony oxide ore. The method comprises the following steps: first, coarse materials are screened out of antimony separation tailings or grinded crude ore of antimony oxide by utilizing a vibrating screen; then, slime is removed by utilizing a hydrocyclone; and finally, a slime-free material automatically flows into a suspension vibration cone concentrator for one-time separation, thereby obtaining antimony concentrate and final tailings. By adoption of the method provided by the invention, the separation recovery rate and the grade of the finally obtained antimony concentrate can reach up to 49.25% and 20.0% respectively; and the separation recovery rate is high, the production efficiency is high, the operation is simple and convenient, the labor intensity, the energy consumption and the cost are low, and the operation environment is friendly.

Description

technical field [0001] The invention relates to a gravity beneficiation method, in particular to a gravity beneficiation method of fine antimony oxide ore. Background technique [0002] Antimony oxide ore is an important raw material for the production of antimony products, and it accounts for a large proportion of antimony ore resources in my country. For example, in the antimony ore produced in the northern area of ​​Xikuangshan, the content of antimony sulfide and antimony oxide each accounts for 50%. It is of great significance to study the efficient recovery of antimony oxide ore beneficiation to improve the utilization rate of antimony resources in my country. [0003] Mineral processing and recovery of antimony oxide minerals, especially fine-grained antimony oxide minerals, is one of the difficult problems in the field of mineral processing at home and abroad. Over the years, despite a large number of researches at home and abroad, no breakthroughs have been made. ...
