400 TPD Rock CIL Gold Processing Plant in Ethiopia
As part of the greenstone belt region in East Africa, Ethiopia hosts abundant quartz + greenstone altered rock containing high‑grade gold ore.
A recent project from one of our Ethiopian customers features
A recent project undertaken by one of our Ethiopian clients includes **quartz‑dominant rock gold with an average grade of about 5 ppm (≈ 5 g/t) — making it ideal for gravity separation followed by carbon‑in‑leach (CIL) processing.
Ore Characteristics and Site Overview
- Ore type: Quartz + greenstone belt altered rock
- Visible gold: Abundant — free granular gold observed after simple washing
- Gold content: ≈ 5 ppm (very good grade for leaching)
- Leaching suitability: Excellent — gold is easy to liberate and react with leaching reagents
At the customer’s site, visible free gold grains were observed after panning and washing, indicating both gravity separation and leaching will be effective for maximum recovery.
Production Target and Gold Plant Capacity
- Desired final gold output: ≈ 1.5 kg/day
- Estimated processing capacity for target output: ≈ 350 TPD
- Planned adjusted capacity: 400 TPD, considering Africa’s production environment and operational flexibility
This throughput ensures stable performance, suitable reagent control, and an optimized balance between investment cost and production performance.
Recommended Processing Flow for This Ore Type
For this rock gold ore with visible gold, the following combined process yields the best recovery:
- Crushing → Grinding — Liberate coarse and fine gold particles.
- Gravity Separation — Capture visible and free gold for early recovery using jigs or centrifugal concentrators.
- CIL (Carbon‑in‑Leach) Leaching — Recover fine gold remaining in the tailings.
- Activated Carbon Adsorption & Desorption — Extract dissolved gold from solution.
- Electrowinning & Smelting — Produce pure gold bullion.
This gravity‑plus‑CIL flow is efficient, environmentally friendly, and proven suitable for similar high‑grade quartz‑type gold ores.
Customer’s Plan and Factory Visit
The Ethiopian customer is preparing to visit our factory in China to inspect our equipment and check a 100 TPD Gold CIL Plant we previously built for another client.
During the visit, we will discuss:
- Equipment selection for 400 TPD capacity
- Layout design according to the local site
- Chemical reagent supply and gold recovery optimization
