【Project Time】May 2024
【Raw ore】Rock gold
【Capacity】700tpd
【Process 】Flotation and Gold CIP Plant
【Country】 Ethiopia

In Ethiopia, Dasen Mining provided a 700tpd gold processing plant design that combined flotation and cyanidation to achieve high recovery rates from fresh ore and historical tailings.

Process Design & Features

• Flotation Stage (Primary Recovery)

Grinding: One-stage closed-circuit grinding for optimal liberation.
Flotation Circuit: 1 rougher + 3 scavengers + 3 cleaners to maximize gold recovery.
Concentrate Treatment: Two-stage mechanical dehydration (filtration) to produce a 46g/t gold concentrate.

• Tailings Cyanidation (Secondary Recovery)

Feed Material: Flotation tailings (~1g/t Au) from 10+ million tons of stored tailings.
Process: Direct cyanide leaching (CIP) to recover residual gold.
Environmental Safety: Low harmful elements; no pollution risks.

Performance & Results
Feed Grade: 1.76g/t Au
Concentrate Grade: 46g/t Au
Overall Recovery: 93%

 

By integrating flotation + tailings cyanidation, this plant ensures:
✅ Maximized gold recovery from both fresh ore and legacy tailings.
✅ Sustainable resource utilization with minimal environmental impact.
✅ Economic viability through advanced, energy-efficient technology.

Dasen Mining’s tailored solution demonstrates how smart process design can unlock value from low-grade resources while maintaining operational and environmental excellence.
