150TPH Heavy Minerals Concentration Plant In Senegal

This heavy mineral concentration plant in Senegal specializes in processing alluvial deposits with peat layers for zircon, rutile, and ilmenite recovery. The complete plant features a 3-stage spiral separation system with customized solutions for peat clay conditions. Designed to process 150 tons per hour (TPH), the plant combines 87 spiral chutes with precise slurry density control (25-30%) for optimal heavy mineral recovery.

Stage 1: Primary Separation & Classification

• The dredge pump will send the slurry to trommel screen hopper,slurry density is better to be about 25-30%. and the slurry pressure (flowing speed) shall not be too big.
• The trommel screen with a 2mm mesh screen, will remove the +2mm waste sand discharging directly to nearby, 0-2mm slurry will first go to an agitation tank (2000*1500mm), because the slurry flow capacity is big from trommel screen, it is necessary to agitate the slurry before sending to 1st stage spiral group, so the solid material in slurry can be distributed evenly to spirals.

Stage2: Multi-Level Spiral Concentration

1. The slurry from the mixing tank will be sent to 1st stage spiral chute group by two slurry pumps (8/6E-AH), 1st stage spiral total of 48 sets, divided into two groups, each group 24 sets spiral, so one pump for one spiral group, each spiral group has one big distribution tank (1800*2000mm).
2. The middling slurry discharged from 1st stage spiral chute will go to two slurry tanks, then use two slurry pumps (4/3C-AH) to send the middling slurry to 2nd stage spiral chute total of 16 sets, only ONE spiral group, with one big distribution tank( 1500*1500mm).
3. The Concentrate ore discharged from 1st stage spiral chute will go to two slurry tanks, and then two slurry pumps(3/2C-AH) sent to 3rd stage spiral for final concentration.
4. The tailings discharge from the 1st stage spiral chute will go to two tailing tanks, and then two slurry pumps (6/4D-AH) sent to the tailing dump which is about 100 meters far away.
5. The concentrate ore discharged from 2 nd stage spiral chute will go to one slurry tank, then use one slurry pump (3/2C-AH) to send the concentrate ore to the big distribution tank (1000*1200mm) of 3rd stage spiral with 6 sets spiral chutes.
6. The tailings discharge from 2nd stage spiral chute will go to a slurry tank, and then use a slurry pump (6/4D-AH) send it to the tailing dump which is 100 meter far away.
7. The final heavy minerals concentrate product that is discharged from 3rd stage spiral chutes will go to one slurry tank, then use a slurry pump (1.5/1C-HH) sent to the concentrate heap on the ground which is 150-200 meters far away.

Note: Considering there is a peat layer in the mine place, which is dark, clay organic matter, an extra submerged slurry pump (model 80-65-160) is necessary to provide extra water to the trommel screen when such material goes through a trommel and spray high pressure water on the material, so the clay can go through trommel more easy and avoid-stuck sieve. So this plant needs a total of 12 sets of slurry pumps on use at the same time.
