JXSC has provided a successful 30TPH alluvial tin processing plant in Uganda. We designed the processing plant flowchart and plant layout drawing according to the client’s requirements. We provided a complete set of plant machines to the mine site, and sent the engineer to the mine site for installation guidance.

Alluvial Tin Processing Plant in Uganda
This is a 30 tph tin processing plant.
The customer’s tin project information:
- Location: Uganda
- Raw ore condition: Alluvial tin mainly with a lot of sticky clay, with coarse tin concentrate and fine tin concentrates as well. Need to enrich coarse tin concentrate into fine powder to improve the grade.
- Customer’s main requirements: 30tph, a higher recovery rate as possible. High configuration. We need a dewatering machine to recycle water and tailing sand with reduced moisture content.
The process is as follows:
- The raw ore is fed into the raw ore bucket above the vibrating feeder by excavators, loaders, etc. The vibrating feeder is equipped with a grid with a 70mm gap; ore smaller than 70mm can be evenly fed into the trommel scrubber.
- The ore smaller than 70mm enters the trommel scrubber for washing (the trommel washer is equipped with two layers of screens with apertures of 7mm and 25mm, respectively). After washing, three types of ores can be obtained: 0-7mm, 7-25mm, and +25mm.
- After washing in the trommel scrubber, the ore larger than 25mm is sent to the ore pile by a belt conveyor. The 7-25mm ore enters a group of roughing jig separators for roughing; the concentrate enters a group of fine jigs for further separating. 0-7mm enters another roughing jig concentrator for enrichment. Then, the concentrate will also enter a cleaner jig concentrator for further separation. The tailings of the roughing jig concentrator will enter a scavenging jig for further concentration. These circled loop jig separators here can improve the recovery rate.
- Since there is a lot of water flowing out with the concentrate, all the concentrate from the jig separators will first enter the dewatering screen for dewatering. After dewatering, the particles on the screen will enter the hammer crusher through a belt conveyor. The undersize will be pumped to the mixing tank by a mud pump. The output of the hammer crusher will flow into the same mixing tank by gravity flow.
- The shaking table further separates to obtain a purer tin concentrate. The output concentrate needs to be directly dried, and then the dry concentrate can be put into 3 disc dry magnetic separators for refining to obtain high-purity tin concentrate.
- The tailings from these jig separators and the tailings from the shaking table will first enter the spiral dewatering machine for dewatering, and then enter the high-frequency vibrating screen for screening. Finally, two products of coarse sand and fine sand are obtained.
FAQ during communication:
Question: Can JXSC provide an agitated feed tank for the shaker table?
Answer: Yes, we can provide the agitated feed tank before the shaker table.
Question: Control panel layout Diagram
Answer: We can provide the electric control panel, just additional cost will be needed. The electric wire & cable layout will be provided after the order is placed.
