Gold Extraction & Recovery Processes
The metallic content of agglomerates is influenced by the gold content, gold recovery, and carbon/ore ratio. For example, it has been determined that ores with 1 g/t of gold will form agglomerates with 1,050 – 1,550 g/t of gold. The recovery can be improved by adding surfactants. This action is similar to the conventional flotation.

ISR
A weak acid solution is delivered into the copper ore body, essentially under gravity pressure. The acid dissolves the copper, creating a copper-rich solution that is then pumped to surface where it is processed in a Solvent-Extraction Electrowinning plant (SX/EW). These plants typically produce 100-pound sheets of pure copper cathode.
Copper Precipitation & Cementation using Scrap Iron
Initially, sponge iron produced at the Ray Mines Division for use in a LPF leach-precipitation-flotation process was used in exploratory tests to develop a suitable apparatus to take advantage of the rapid precipitation rate and efficient iron utilization for the recovery of copper from dilute solutions.
