Problems solved by technology

[0003] At present, the beneficiation of pegmatite-type spodumene mainly includes dense medium separation and flotation processes. For ores with fine particle size and low grade, dense medium separation has the advantages of low beneficiation cost, simple process and little environmental pollution, but has the disadvantage of low grade of spodumene concentrate. Flotation has a wide range of process adaptability, but there are Disadvantages of high mineral processing cost

Embodiment 1

[0031] Embodiment 1, a kind of beneficiation method for pegmatite type spodumene, its steps are as follows:

[0032] (1) Crushing, screening and classification: The spodumene ore is crushed and screened to a suitable particle size, and then divided into two grades of coarse and fine grades by the classification operation, and the classification particle size is controlled at 2mm; , desliming operation;

[0033] (2) Dense medium pre-selection: the coarse-grained materials after washing and desliming are fed into the heavy medium sorting operation, and the heavy medium concentrate and the heavy medium tailings are sorted;

[0034] (3) Grinding and flotation: the fine-grained minerals and the sludge produced by the desliming operation are fed into the classification operation to remove a part of the fine ore sludge; the coarse concentrate of the heavy medium after the desliming operation and the underflow of the desliming operation are respectively fed to Into grinding, flotatio...

Embodiment 2

[0048] Embodiment 2, a kind of beneficiation method for pegmatite type spodumene, its steps are as follows:

[0049] (1) Crushing, screening and classification: The spodumene ore is crushed and screened to a suitable particle size, and then divided into two particle sizes, coarse and fine, and the classification particle size is controlled at 4mm;

[0050] (2) Pre-selection of heavy medium: the coarse-grained materials in the classification operation are first fed into the cylindrical washing machine for scrubbing, and the scrubbed pulp is fed into a first stage of desliming operation. The underflow is fed into the heavy medium sorting operation, and the heavy medium concentrate and the heavy medium tailings are sorted out. The heavy medium concentrate and tailings are fed into the next process after the de-intermediation operation, and the overflow and screening of the first-stage desliming operation The fine-grained materials of the operation are fed into the second-stage de...

Embodiment 3

[0057] Embodiment 3, a kind of beneficiation method for pegmatite type spodumene, its steps are as follows:

[0058] (1) Crushing, screening and grading: Spodumene ore is crushed to a suitable size by crushing and screening, and then divided into two grades, coarse and fine, and the grading size is controlled at 3mm;

[0059] (2) Pre-selection of heavy medium: the coarse-grained materials in the classification operation are first fed into the cylindrical washing machine for scrubbing, and the scrubbed pulp is fed into a first stage of desliming operation. The underflow is fed into the heavy medium sorting operation, and the heavy medium concentrate and the heavy medium tailings are sorted out. The heavy medium concentrate and tailings are fed into the next process after the de-intermediation operation, and the overflow and screening of the first-stage desliming operation The fine-grained materials of the operation are fed into the second-stage desliming operation, and the part...

Abstract

The invention relates to a beneficiation method for pegmatite-type spodumene, which belongs to the technical field of mineral processing. Firstly, the spodumene ore is crushed and screened, and then divided into two grades of coarse and fine through classification, and the coarse-grained material is fed into Ore washing and desliming operations, the deslimed products are sent to the heavy medium separation operation, and the heavy medium rough concentrate and heavy medium tailings are separated; the heavy medium tailings are sent to the tailings for dehydration after desliming; fine-grained Grade minerals and the slime produced by the desliming operation are fed into the classification operation to remove a part of the fine slime; the heavy medium coarse concentrate and the underflow of the desliming operation are fed into the grinding and flotation operations respectively after the desliming operation, and finally Obtain spodumene concentrate. The method of the present invention has a good separation effect. The heavy medium can be used to remove some minerals such as quartz and feldspar with relatively coarse particle size, and the flotation process can be used to remove mica, quartz and feldspar with fine particle size. Minerals have the characteristics of low grinding energy consumption, low beneficiation cost, and remarkable economic effects.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and particularly relates to a beneficiation method for pegmatite-type spodumene. Background technique [0002] Lithium is an important new energy material, and lithium-containing power batteries are the preferred battery material for electric vehicles. The basic sources of lithium products are mainly ore extraction and brine extraction. Due to the high ratio of magnesium to lithium or bad natural conditions, the extraction of lithium from brine has not been able to reach production, and the extraction of lithium from ore is mainly. At present, the extraction of lithium from ore mainly comes from the spodumene deposit of pegmatite. High-grade lithium concentrate products, followed by lithium smelting and material processing. [0003] At present, the beneficiation of pegmatite-type spodumene mainly includes dense medium separation and flotation. For ore with finer particle size and lo...
