Project Overview
This project involves the heap leaching of 100,000 tons of oxidized gold ore in Zimbabwe. The ore body is characterized by its favorable oxidation state, which enables efficient gold recovery using conventional heap leaching techniques.
Ore Characteristics
- Ore Type: Oxidized gold ore
- Gold Grade: 1–2 grams per ton (g/t)
- Oxidation Level: Well-oxidized, conducive to heap leaching
- Estimated Total Gold Content: 100–200 kilograms
Leaching Process
- Leaching Method: Heap leaching
- Leaching Agent: Sodium cyanide (NaCN)
- NaCN Consumption: 300 grams per ton (g/t)
- pH Control: Maintained between 9 and 10 to optimize leaching conditions and minimize cyanide loss
- Recovery Rate: 83%
Operational Plan
- Total Ore to be Processed: 100,000 tons
- Production Timeline: 6 months
- Estimated Gold Recovery: 83–166 kilograms of gold over the project duration
Key Advantages
- High Recovery Efficiency: With an 83% recovery rate, the project demonstrates strong metallurgical performance.
- Low Reagent Consumption: Sodium cyanide usage is within a cost-effective range for oxidized ore.
- Short Timeline: Six-month production schedule allows for rapid return on investment.
- Favorable Ore Type: The oxidized nature of the ore enhances leaching kinetics and simplifies processing.
Conclusion
The Zimbabwe 100,000 Tons Heap Leaching Gold Project is a viable and economically attractive venture, leveraging favorable ore characteristics, efficient leaching methodology, and a short production cycle. With proper management and environmental controls, it offers a solid return potential within a manageable risk profile.
