P1331: Enhanced treatment of Refractory Au & base ores
Project Number: P1331
Status: Open for Sponsorship
Amira Program Manager: Bright Foli
This project within the mineral processing framework is in responds to industry needs of treating refractory ores. Refractory gold ores is defined as ore that is difficult to recover through conventional circuit of crush-grind-leach.
This project will utilize both new research and applied to solve peculiar problems or combination of problem from participants. The project will initially start with sites in West Africa sub-region and expand to other jurisdictions like South America and Australia as the project progresses. The objective of the project is to:
- Characterise the extent of “refractoriness” in a way that makes sense for metallurgical route optimisation.
- Identify and design of optimum cost-effective processing routes for various refractory ores for Au and other primary metals.
- Identify of cost-effective treatment of by-products that may be present in Au ores, especially base metals including copper.
- Establish a safe and cost-effective route for trace elements including Antimony, Pb and Arsenic in Au ores.
- Continuous skills transfer and involvement of sponsor companies’ stakeholders
P1331 projects to characterize, research for solutions, conduct techno-economic analyses and trial solutions for various type of “refractoriness” that cover, among others:
·Slimes and clay problems, Antimony and Arsenic in ore issues, Grain size fine dissemination, Sulphide enclosed metals and the like, Carbonaceous associations (Laterite with settling and carbon management issues),
many more categories that describe mineralogical and metallurgical challenges experienced currently, especially in West Africa, as a start, but global in general
- P1331 will develop new methodologies and workflows for mineralogical characterisation of refractory orebodies that can be upscaled to understand the extent of refractoriness of the orebody.
- Optimal recovery methods and recovery process proposition will be explored for the orebodies and diverse techno-economic analysis (TEA) will be performed to offer practical solutions.
- Skills and technology transfer will be at the forefront of the project, with the new tools, methods and workflows developed
The project is currently under development and open to sponsors. Please contact Bright Foli at bright.foli@amira.global for more information.
