:: Further Developments in Refractory Gold Treatment  

Australian hydrometallurgical specialist Intec and its largest shareholder, Ivanhoe Mines, plan to form a 50:50 joint venture to fund the further development of Intecís refractory gold-treatment process. The two companies have reached an agreement in principle whereby some A$1 million will be used to fund further test work of the Intec refractory gold process (IRGP), the construction of a pilot plant in Sydney capable of continuous operation to conduct paid test work and marketing of the technology.

Intec says that its chloride-based process can remove arsenic, antimony and bismuth from refractory gold concentrates in a single step. Subsequent gold dissolution and deposition can be achieved without cyanide.
