Thus, it can be applied to a wide range of lithium feedstock, with low energy consumption, high metal recoveries and extensive by-product credits.
Further, SiLeach® has applications beyond the recovery of lithium from silicates. It has, for example, been tested on refractory gold ores to remove siliceous gangue material from the ore prior to cyanide recovery of gold. Therefore, SiLeach® could well become the benchmark for extraction of a wide range of metals from silicates.
