Spodumene particle-size double-dense-medium-flotation benefication method
A beneficiation method and spodumene concentrate technology are applied in the field of spodumene classifying double meso-flotation beneficiation, which can solve the problems of low concentrate grade, high sorting cost, and coarse-grained minerals that cannot be pre-segregated. selection and other issues to achieve the effect of avoiding pollution and avoiding impact

Example Embodiment
[0031] Example 1
[0032] This embodiment takes a spodumene mine in Sichuan as the research object, and the specific test includes the following steps:
[0033] (1) Crushed the raw ore to 15mm, and remove the -8mm size by sieving.
[0034] (2) The washed spodumene ore enters a high-density heavy medium (ferrosilicon) cyclone with a density of 3.0kg / L for separation, and coarse-grained light products and heavy products are obtained. The coarse-grained spodumene concentrate I is obtained after sieving.
[0035] (3) The light product in step (2) is naturally dried after being deintermediated by a sieve, and then combined with the product under the sieve in step (1) to be finely crushed to 4mm, and then degraded to a size of -1mm after being classified by a cyclone.
[0036] (4) In step (3), the cyclone settles the sand into the low-density heavy medium (ferrosilicon) cyclone with a density of 2.8kg / L for separation, and obtains fine-grained light products and heavy products. The fine-gra...

[0041] Example 2
[0042] The ore used in this example is the same as in Example 1. The specific test includes the following steps:
[0043] (1) Crushed the raw ore to 15mm, and remove the -6mm size by sieving.
[0044] (2) The washed spodumene ore enters a high-density heavy medium (ferrosilicon) cyclone with a density of 3.1kg / L for separation, and coarse-grained light products and heavy products are obtained. The coarse-grained spodumene concentrate I is obtained after sieving.
[0045] (3) The light product in step (2) is naturally dried after being deintermediated by a sieve, and then combined with the product under the sieve in step (1) to be finely crushed to 4mm, and then degraded to a size of -1mm after being classified by a cyclone.
[0046] (4) In step (3), the cyclone settles the sand into the low-density heavy medium (ferrosilicon) cyclone with a density of 2.9kg / L for separation, and obtains fine-grained light products and heavy products. The fine-grained spodumene conce...
Example Embodiment
[0051] Example 3
[0052] This embodiment takes a certain spodumene in Jiangxi as the research object, and the specific test includes the following steps:
[0053] (1) The raw ore is coarsely crushed to 15mm, and the -8mm particle size is removed by screening.
[0054] (2) The washed spodumene ore enters a high-density heavy medium (ferrosilicon) cyclone with a density of 3.1kg / L for separation, and coarse-grained light products and heavy products are obtained. The coarse-grained spodumene concentrate I is obtained after sieving.
[0055] (3) The light product in step (2) is naturally dried after being deintermediated by a deintermediation sieve, and is combined with the product under the sieve in step 1) to be finely crushed to 4mm, and then degraded to -1mm particle size after being classified by a cyclone.
[0056] (4) In step (3), the cyclone settles the sand into the low-density heavy medium (ferrosilicon) cyclone with a density of 2.9kg / L for separation, and obtains fine-grained ...
