Problems solved by technology

[0002] Spodumene concentrate can be widely used in metallurgy, ceramics, glass, rubber, paper and other industries. At present, the beneficiation process of spodumene is generally to first crush the ore, grind it to -200 mesh, accounting for 60-70%, and then add Chemical reagents are used for flotation separation, the process cost is high, environmental pollution is serious, the concentrate particle size is small and polluted by chemicals, and the conversion rate of spodumene to manufacture lithium salt is not high

Embodiment 1

[0015] Spodumene ore dense medium-strong magnetic beneficiation process:

[0016] The first step of crushing: crushing the spodumene ore that does not contain weak magnetic minerals, so that the spodumene ore becomes a spodumene ore that has dissociated most of its monomers;

[0017] The second step of ore washing: wash the crushed spodumene ore through the ore washing screen or other ore washing equipment to remove the part of the slime less than 0.5 mm;

[0018] The third step of beneficiation: ferrosilicon powder and water are mixed in a weight ratio of 2:1 to make a dense medium suspension, the spodumene ore after ore washing is mixed with the dense medium, and fed into the dense medium cyclone at a certain pressure of 0.06Mpa After sorting, the ore is divided into light products and heavy products; the light products become tailings after being stripped through the de-mediation sieve, and the main minerals are quartz, feldspar, biotite, etc.; Mine, the main product is sp...

Embodiment 2

[0020] Spodumene ore dense medium-strong magnetic beneficiation process:

[0021] The first step of crushing: crushing the spodumene ore containing weak magnetic minerals, so that the spodumene ore becomes spodumene ore with most of its monomers dissociated;

[0022] The second step of ore washing: wash the crushed spodumene ore through the ore washing screen or other ore washing equipment to remove the part of the slime less than 0.5 mm;

[0023] The third step of beneficiation: ferrosilicon powder and water are mixed in a weight ratio of 4:1 to make a dense medium suspension, the spodumene ore after ore washing is mixed with the dense medium, and fed into the dense medium cyclone at a pressure of 0.20Mpa. Sorting, the ore is divided into light products and heavy products; the light products become tailings after being de-mediumed by the de-mediation sieve, and the main minerals are quartz, feldspar, biotite, etc.; the heavy products are de-mediumed by the de-medium sieve and...

Embodiment 3

[0026] Spodumene ore dense medium-strong magnetic beneficiation process:

[0027] The first step of crushing: crushing the spodumene ore containing weak magnetic minerals, so that the spodumene ore becomes spodumene ore with most of its monomers dissociated;

[0028] The second step of magnetic separation: using a strong magnetic separation process for separation to remove weak magnetic minerals;

[0029] The third step of ore washing: wash the crushed spodumene ore through the ore washing screen or other ore washing equipment to remove the part of the slime less than 0.5 mm;

[0030] The fourth step of mineral processing: ferrosilicon powder and water are mixed at a weight ratio of 3:1 to make a dense medium suspension, and the spodumene ore after ore washing is mixed with the dense medium, and fed into the dense medium cyclone at a pressure of 0.10Mpa. Sorting, the ore is divided into light products and heavy products; the light products become tailings after being de-mediu...

Abstract

The present invention relates to an ore separation method, in particular, it relates to a spodumene ore-heavy medium-strong magnetic separation process. Said separation process includes the following steps: (1), crushing spodumene ore; (2), washing the crushed spodumene ore to remove mire; and (3), separation: mixing spodumene ore and heaving medium, applying pressure with 0.05-0.20MPa into heavy medium cyclone separator to make separation so as to obtain concentrate spodumene.

Description

Technical field: [0001] The invention relates to an ore production process, especially a spodumene beneficiation process. Background technique: [0002] Spodumene concentrate can be widely used in metallurgy, ceramics, glass, rubber, paper and other industries. At present, the beneficiation process of spodumene is generally to first crush the ore, grind it to -200 mesh, accounting for 60-70%, and then add Chemical reagents are used for flotation separation, the process cost is high, the environment is seriously polluted, the concentrate particle size is small and polluted by chemicals, and the conversion rate of spodumene to manufacture lithium salt is not high. Invention content: [0003] The object of the present invention is to overcome the above-mentioned problems and provide a spodumene heavy-media beneficiation process, which is simple and easy to operate, and the resulting product has good quality and high yield. [0004] The technical scheme that the present inven...
