Flotation of difficult ore under modified chemistry conditions
R&D Project Summary
Nickel sulfide ores, mined to produce concentrates for the nickel smelting infrastructure, are becoming lower in grade and with increasingly complex mineralogy. Metallurgists have been able to adapt standard processing flow sheets to cope with the processing of these ores, but sometimes with only limited success.
Our metallurgical team recently developed a new set of process conditions that dramatically improves the flotation and separation of nickel sulfides from problematic gangue minerals, in particular talc. This has allowed nickel concentrate of good grade, at acceptable recoveries, with impurities (such as MgO) at levels acceptable to smelters.
This process chemistry driven approach has yielded some impressive results and opens up an opportunity, through further development to process ores currently considered untreatable.
Subsequent to financing, this R&D Initiative can quickly deliver results. It builds on the sum of experiences already acquired by Strategic Metallurgy on this topic.
A joint budget of $900,000 is expect to be require in order to bring this initiative to the pre-commercial deployment stage.
- Multiple potential applications that can open new ore body (difficult ones) opportunities.
- Financing bottom line improvement for current producers with improved recuperation rates.
- Environmental benefits of better metal separation in the early phase of the recovery process (Less chemical, less energy).
