Evidence status: Reference case prepared from user-supplied project notes. Keep noindex until source drawings, site permission and approved public wording are confirmed.
Project positioning
This reference is useful for larger alluvial gold projects where the design conversation must cover the whole ore handling route: screening, washing, gravity recovery, concentrate cleaning, water balance and tailings handling.
The supplied notes describe a 200 t/h alluvial gold line in the East Africa region. It is best used as a process-logic reference rather than a public performance case.
Known project facts
- Mineral: alluvial gold
- Location: East Africa region
- Nominal capacity: 200 t/h
- Screening target commonly controlled below 25 mm
- Slurry density after washing: approximately 30%-40% solids in the supplied notes
- Main route: raw ore screening, trommel scrubber washing, centrifugal concentration and concentrate cleaning
Process route
The useful public lesson is the sequence:
- Remove oversize before the washing duty overloads.
- Use scrubber or trommel washing to release gold-bearing fractions from clay and mixed gravel.
- Send controlled slurry to centrifugal concentration.
- Treat concentrate with cleaning equipment such as shaking tables or spiral chutes when test work supports it.
- Keep tailings, water return and settling space in the early design discussion.
Equipment scope
The supplied notes referenced circular vibrating screens, scrubber washing equipment, centrifugal concentrators, shaking tables, spiral chutes and spiral washing equipment. For a 200 t/h route, equipment selection must be checked against clay behavior, feed variability, water supply and maintenance access.
Mercury handling note
The source notes included amalgamation and mercury recovery system descriptions. Mercury is not recommended by default by GoldConcentrator.com. It should not be proposed in public sales material unless local law, environmental controls, operator safety and a documented closed handling system are confirmed.
For this website, the publishable process focus should remain screening, washing, gravity recovery and controlled concentrate cleaning.
Quotation and design lessons
Large alluvial projects fail when washing, water and tailings are treated as afterthoughts. A high-throughput quotation should check screen cut size, scrubber retention, water consumption, pump duty, concentrate cleaning, tailings placement and spare parts before final equipment sizing.
