What Does Jenny Say?
30 TPH Alluvial Tin Process Plant in Uganda
1. Customer’s Tin Project Information
Localisation : Ouganda
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.
Principales exigences du client : 30tph, a higher recovery rate as possible. High configuration. We need a machine de déshydratation to recycle water and tailing sand with reduced moisture content.
2. Our Process Design & Solution
Process Description
Stage 1: Primary Screening & Classification
- Excavators load raw ore into vibrating feeders equipped with 70mm grizzly screens
- Sub-70mm material passes through for scrubbing, while oversize is rejected
- The trommel scrubber features dual screening layers (7mm and 25mm apertures)
- Output produces three classified fractions: 0-7mm, 7-25mm, and +25mm materials
Stage 2: Multi-Stage Jig Separation System
- +25mm fraction diverted directly to stockpile via conveyor belt
- 7-25mm fraction undergoes primary jig separation:
1. Rougher gabarit produces initial concentrate for cleaning jigs
2. Closed-circuit design maximizes mineral recovery - 0-7mm fraction processed through dedicated jig circuit:
1. Separate the rougher jig from the cleaner jig refinement
2. Scavenger jig processes rougher tailings
Stage 3: Concentrate Dewatering & Preparation
- All jig concentrates first pass through dewatering screens
- Screen oversize is conveyed to the hammer crusher for size reduction
- Screen undersize is pumped to the mixing tank as slurry
- Crusher discharge flows by gravity to the same mixing tank
Stage 4: Final Concentration & Refinement
- Shaking tables upgrade concentrate purity
- Dried table concentrate passes through triple-disc dry magnetic separators
- Final product: High-grade tin concentrate
Stage 5: Tailings Management System
- Combined jig and table tailings processed through:
1. Spiral dewaterers for moisture reduction
2. High-frequency vibration screens - Produces two tailings products:
1. Coarse sand fraction
2. Fine sand fraction

This project underscores JXSC’s capability to deliver high-recovery, low-waste solutions for alluvial tin miners, combining robust equipment with adaptable processes for varied ore profiles.
Key Process Achievements
- Advanced trommel scrubbing system with dual-layer screening (7mm/25mm) effectively removed sticky clay and pre-classified ore.
- Multi-stage jigging circuit (roughing—cleaning—scavenging) maximized recovery of coarse and fine tin particles.
- Integrated dewatering & water recycling (spiral dewaterer + high-frequency screens) reduced tailings moisture and minimized water waste.
- Final purification via shaking tables and dry magnetic separators ensured high-grade tin concentrate output.
Client-Centric Design Highlights
- Scalable configuration: Modular layout allows future capacity upgrades.
- Labor-efficient operation: Streamlined workflow requiring only 5 personnel for full plant control.
- Customized automation: Optional agitated feed tanks and electric control panels provided for stable shaker table performance.
