Simulating the Blanking of Preg Robbers in Gold Ores by Treating Activated Carbon with Hard Paraffin Wax

As part of a general review of processing double refractory ores through Barrick Gold's autoclaves/CIL facility at Goldstrike, NV, blanking the gold cyanide adsorbing native carbon in the ore with hard (m.p. >55 C) paraffin wax was proposed. To avoid interference from other ore constituents...

Description
Summary:As part of a general review of processing double refractory ores through Barrick Gold's autoclaves/CIL facility at Goldstrike, NV, blanking the gold cyanide adsorbing native carbon in the ore with hard (m.p. >55 C) paraffin wax was proposed. To avoid interference from other ore constituents in the exploratory testwork, commercial activated carbon was substituted for native carbon to establish the best conditions for deactivation of carbon with molten wax.
