Problems solved by technology

[0007] The purpose of the present invention is to provide a spodumene grading method for the problems of low concentrate grade, high cost of sorting, lack of pre-sorting of coarse-grained minerals, and poor adaptability of single beneficiation in the existing spodumene beneficiation. Level double medium-flotation beneficiation method, this method adopts the double medium of classification level after the raw ore is crushed, and performs pre-separation of coarse-grained and fine-grained spodumene to obtain coarse-grained and fine-grained spodumene concentrate products; The light tailings of medium beneficiation are deslimed after grinding, and the sand is set for flotation of fine-grained spodumene to obtain fine-grained spodumene concentrate products

Embodiment 1

[0032] In this embodiment, a certain spodumene ore in Sichuan is taken as the research object, and the specific test includes the following steps:

[0033] (1) Coarsely crush the raw ore to 15mm, and remove the -8mm particle size by sieving.

[0034] (2) The spodumene ore after ore washing enters the high-density heavy medium (ferrosilicon) cyclone with a density of 3.0kg / L for sorting, and obtains coarse-grained light products and heavy products, and the heavy products are de-medium Coarse-grained spodumene concentrate I was obtained after sieving and de-intermediation.

[0035] (3) The light product in step (2) is de-mediumed through a de-medium sieve, then dried naturally, and combined with the product under the sieve in step (1) to be finely crushed to 4mm, and the -1mm particle size is removed after classification by a cyclone.

[0036] (4) In step (3), the cyclone in step (3) enters the low-density heavy medium (ferrosilicon) cyclone with a density of 2.8kg / L for sortin...

Embodiment 2

[0042] The ore used in the present embodiment is identical with embodiment 1, and concrete test comprises the following steps:

[0043] (1) Coarsely crush the raw ore to 15mm, and remove the -6mm particle size by sieving.

[0044](2) The spodumene ore after ore washing enters the high-density heavy medium (ferrosilicon) cyclone with a density of 3.1kg / L for sorting, and obtains coarse-grained light products and heavy products, and the heavy products are de-medium Coarse-grained spodumene concentrate I was obtained after sieving and de-intermediation.

[0045] (3) The light product in step (2) is de-mediumed through a de-medium sieve, then dried naturally, and combined with the product under the sieve in step (1) to be finely crushed to 4mm, and the -1mm particle size is removed after classification by a cyclone.

[0046] (4) The cyclone in step (3) is gritted into a low-density heavy medium (ferrosilicon) cyclone with a density of 2.9kg / L for sorting, and fine-grained light p...

Embodiment 3

[0052] The present embodiment takes a certain spodumene in Jiangxi as the research object, and the specific test includes the following steps:

[0053] (1) Coarsely crush the raw ore to 15mm, and remove the -8mm particle size by sieving.

[0054] (2) The spodumene ore after ore washing enters the high-density heavy medium (ferrosilicon) cyclone with a density of 3.1kg / L for sorting, and obtains coarse-grained light products and heavy products, and the heavy products are de-medium Coarse-grained spodumene concentrate I was obtained after sieving and de-intermediation.

[0055] (3) The light product in step (2) is de-mediumed through a de-medium sieve, then dried naturally, and combined with the product under the sieve in step 1) to be finely crushed to 4mm, and then classified by a cyclone to remove the -1mm particle size.

[0056] (4) The cyclone in step (3) is gritted into a low-density heavy medium (ferrosilicon) cyclone with a density of 2.9kg / L for sorting, and fine-grain...

Abstract

The invention discloses a spodumene particle-size double-dense-medium-flotation benefication method, and belongs to the technical field of mineral machining. The method adopts two sections of crushingflow; through screening (or classification) treatment, high-density dense medium separation and low-density dense medium separation, thick-particle spodumene concentrate products and fine-particle spodumene concentrate products are obtained; cyclone overflowing products are concentrated for ore grinding; a cyclone is used for mud removal; and sunk sand enters the flotation operation to obtain fine-particle spodumene concentrate products. The method has the advantages of high adaptability, low production cost, capability of obtaining the concentrate products with different particle sizes and reduction of the crushing and ore grinding energy consumption and the medicament use level.

Description

technical field [0001] The invention relates to a spodumene classifying double media-flotation beneficiation method, which belongs to the technical field of mineral processing. Background technique [0002] my country's spodumene mineral resources are abundant, but its utilization rate is very low. The structure and composition of spodumene ore are complex, the distribution of minerals is uneven, the gangue minerals are various, and the mudification is serious. Raw ore often contains a lot of easy-to-select coarse-grained grades, but after grinding, it is disturbed by ore slime, which makes the composition of ore slurry complex and the selectivity of reagents is reduced, making it extremely difficult to recover spodumene by flotation, and it is difficult to obtain high-grade and high-recovery products. Concentrate products. [0003] The spodumene beneficiation methods commonly used in the industry include flotation and dense medium beneficiation, and cooperate with other b...
