Particles of different electrical charges
or polarities are separated in an electric
field because they follow different motion
trajectories. This way, valuable conductive material is
separated from non conductive ore or slag.
The smaller the particle, the greater the amount of gold recovered. The ultra-fine raptor mill is a new concept that allows fine grinding to extract minerals, including precious metals, more efficiently.
NaCl leaching is one of the most
promising alternative processes
because it is less toxic, has faster
dissolving kinetics, has fewer gold
passivation issues and is excellent at
leaching refractory ores
When a DC pulsed, electric power is
delivered to a hydrogen containing
gas, it ionizes, resulting in various radicals. The hydrogen radicals formed
in the molten metal react with the contaminants in the solution.
Traditional electrowinning requires
recirculating the treated solution for further processing, but cyclone electrowinning technology is a straightforward, one-step approach for treating metal ion solutions.
