GlyCat can also be used at existing gold processing plants. It's essentially a drop-in additive. "No novel processing equipment is required," Briggs said.
Detoxification processes are used to reduce the concentrations of toxic constituents in tailings streams and process solutions, either by dilution, removal, or conversion to a less toxic chemical form (sometimes referred to as"destruction" or "degradation" in the case of toxic cyanide species). The objective is to produce an …
Traditionally, gold bearing low-grade ores and other secondary materials are subjected to a cyanide leaching process to bring gold into solution as its cyanide complex. Subsequently, the gold containing solutions are subjected to carbon adsorption for concentration and separation of gold [1,2].
