you won't like this either. in case you missed it - taken directly from the compliance statement - to make sure everyone knows the risks and make the decision themselves.
Aurostibite is notoriously uneconomic because it is a true "refractory" mineral, insoluable in cynade. Arsenopyrite is similar. In the past it's been treated conventionally by roasting the hell out of it, but due to environmental concerns, particularly with arsenic, this practice has stopped. A POX circuit could treat this, same with the BIOX process. But the problem with this is they are slow. You need big capacity to be able to have economic throughput.
