Simultaneous leaching and metals recovery
R&D Initiative Summary
Treatment processes usually become more expensive, both to build and operate, as they become more complex. Each unit operation added to a process flowsheet requires more tanks, pumps, piping, control systems, etc, to integrate it into the complete operation.
One of the standout metallurgical successes of the past 40 years, has been carbon-in-pulp (CIP) technology for the treatment of gold ores. CIP replaced the much more complex leach-CCD- Merrill-Crowe plants with a process where gold could be recovered without undergoing the often difficult liquid-solids separation step. This transformed the type of ores that could be treated and resulted in the gold boom of the 1980’s.
Our metallurgical team is working on a method that combines leach and metal recovery into a much simpler set of equipment that could result in significant capital cost savings in most nickel plant. Potentially game changing this method is being designed with new and existing processing operations implementation in mind.
Initial process development followed by proof-of-concept testing and process is expected to be fairly quick. This technology has the potential to create positive results quickly for St-Georges and the industry.
This R&D initiative is high on St-Georges and Strategic’s development list. An initial budget of $1,200,000 is expected to be required and the development is co-financed between St-Georges and Strategic Metallugy Pty at the rate of 70-30.
