100TPH Alluvial Tin Ore Gravity Separation Plant In Nigeria

1. Feeding, Washing: vibrating feeder, trommel scrubber

Vibration feeder with 70mm grille bars, more than 70mm materials are transported to one side, and materials smaller than 70mm are evenly fed to the trommel scrubber, which efficiently removes surface sediment or impurities and effectively separates valuable tin ore from waste. .

2. Gravity separation: jig separators, shaking tales

• After being cleaned and screened by the drum washing machine, the +7mm material is transported to the side by a belt conveyor, and the -7 mm material enters the jig separator. Among them, materials measuring 2-7mm are sorted through two 2-2 jig separators, and the concentrate can be directly obtained and added to the slurry pool.
• Materials smaller than 2mm enter the 4-2 jig separators, and the concentrate enters the distribution barrel. It enters the two-stage shaking table for sorting evenly, and the concentrate grade is higher.

3. Classification, dewatering: spiral classifier, dewatering screen

• Jig tailings dehydration

The spiral classifier helps eliminate environmental pollution caused by low slurry concentration; the dewatering screen not only improves the recovery efficiency, but also minimizes water consumption through its excellent dehydration capability. The spiral classifier and dewatering screen perform double dehydration of the tailings slurry, which can better control the particle size distribution and moisture content in the tailings. Eventually, the dry tailings are transported aside.

• Shaking table tailings dehydration

After sorting by the shaking table, the tailings enter the dewatering screen and the sedimentation tank.

4. Drying, Magnetic separation: three disc magnetic separator

The gravity-separated concentrate is dried in a drying shed, and magnetically separated minerals, weakly magnetic minerals, non-magnetic minerals, and tin concentrate are finally separated by a 3-disc magnetic separator.
