INTEC Gold

The Intec Gold Process offers particular advantages for refractory or arsenical feedstocks. The Intec Gold Process offers particular advantages for refractory or arsenical feedstocks.As example, where arsenic is present in a mineral concentrate (perhaps as arsenopyrite), the conventional roasting technologies become both potentially environmentally hazardous and expensive, due to the formation of volatitle arsenic trioxide. 

By contrast, the Intec Process can leach the arsenopyrite to liberate the gold while leaving the arsenic behind as safe, environmentally stable ferric arsenate, an analogue to the naturally-occurring mineral scorodite.The Intec Gold Process can be run without the use of cyanide for projects where this is a particular advantage, or can be combined with conventional technologies for efficient gold recovery with minimal technical risk.
