The innovative technologies in question substantially lower both capital and processing expenses by 30-50%, while also enhancing recovery rates in complex deposits. They enable on-site production of metal or high-value products, significantly improving the economics at the mine gate compared to traditional concentrators.
These technologies are particularly effective for high-acid-consuming carbonate (oxide) hosted ores, offering an environmentally friendly alternative that reduces the carbon footprint compared to conventional methods. They focus on base metals crucial for the electric vehicle revolution and energy generation and storage technologies, aligning perfectly with Environmental, Social, and Governance (ESG) policies.
ORF Laterite demonstrates impressive recovery rates of over 90% for both nickel and cobalt, outperforming the Caron method and closely matching the high recovery rates of Pyrometallurgical and HPAL processes.
The ORF Laterite method offers potentially lower environmental impact with the production of inert residue and reduced residue volume. Additionally, it operates at medium energy requirements without the need for water removal from ore, suggesting cost-effective and energy-efficient operations compared to the other methods.
