Cyanide leaching is the most effective gold extraction method, but it requires a high consumption of cyanide which can pose severe risks to the environment and to human health. Increasing gold extraction percentages can be environmentally challenging, especially in refractory ores.
ExtracTech is our advanced biopolymer additive, designed to optimize your precious metal extraction process during cyanidation. With no additional capital outlay, the ExtracTech liquid polymer can be introduced during the cyanidation process without additional equipment.
As an additive to your existing cyanidation process, ExtracTech can also reduce your cyanide usage by up to 20%.
Our non-toxic, inert* solidification reagents convert tunneling and drilling spoils to a manageable solid, on-site, in minutes. The solidified waste can then pass Slump and Paint Filter Tests, and typically requires a dose of less than 1.0% wt/wt.
The solidified slurry is transferred to dump trucks to be transported directly to the final disposal site. It reduces risks, lowers operational costs, and promotes a safer, more sustainable waste management approach in tunneling projects.
