20TPH Alluvial ＆ Rock Tin Tantalite Ore Process Plant In Zimbabwe

JXSC custom a complete 20TPH alluvial and rock tin tantalite ore processing plant for Zimbabwean customers. We provide customers with all-around services, including consulting in the early stage of mining projects, designing and drawing flow charts, and providing complete sets of processing equipment. At the same time, we provide a detailed layout design and corresponding infrastructure diagram.

The original ore tin-tantalite is alluvial mixed rock type, 50% alluvial ore and 50% rock ore. The alluvial ore part contains clay, so large particles need to be washed and separated, crushed to smaller sizes, then Ta and Nb ore are separated using gravity separators. Finally, the iron ore is removed by magnetic separation.

1. Washing & Screening: trommel scrubber

The loader or excavator feeds the material to a hopper, and the belt conveyor feeds the material into the drum washing machine to clean and screen the raw ore into 0-2mm, 2-10mm ore.

2. Gravity separation: jig separator

The 0-2mm material enters the slurry pool, and the 2-10mm material enters the jig to screen 2-10mm tin concentrate.

3. Crushing & screening: hammer crusher, double roll crusher, high frequency vibrating screen

More than 10mm of materials are transported to the warehouse by belt conveyor, and the materials are fed into the hopper by forklift. Then use the chute feeder to feed into the hammer crusher to less than 10mm.

The coarsely crushed material is transported to the roller crusher with a belt conveyor and crushed to less than 2mm. The finely crushed materials are sent to the high-frequency sieve for screening, and the materials more than 2mm are returned to the roller crusher for crushing again to reasonable particle size. The screened 0-2mm material flows into the pulp pool (the same pool as the 0-2mm material discharged from the trommel scrubber).

4. Gravity separation: spiral chute, shaking table

Send all 0-2mm materials into the spiral chute with a slurry pump. There are two-stage spiral chutes: the first stage processing 0-2mm materials and three discharge ports (concentrate, middling and tailings). Then the middlings ore are sent to the second stage for recycling with a slurry pump. Finally, the concentrates from both stages are sent to shaking tables to recover fine concentrates.

5. Magnetic separation: 3pcs Disc Dry Magnetic Separator

The concentrate is dried in the sun, then tin, tantalite and iron ore are separated using a three-disc dry magnetic separator.
