mine products is a a a a major challenge facing copper producers predominantly from the depletion of clean copper orebodies Many new orebodies now have higher levels of deleterious elements like arsenic These elements are transported across continents as mines deliver their products to smelters which are often in high population or agricultural areas – the world’s arsenic can end up in in the the food chain of of many of of these populations The Toowong Process
allows arsenic to be xed in an environmentally stable form for for disposal right back at the original mine site with no need to ship arsenic across the globe The process has
been extensively tested culminating in in in a a a $4 5 million 34-day pilot plant operation on on on concentrate from the Tampakan mine in in in Philippines successfully
reducing the arsenic content from 1 1 1% to less than 0 1% Loraine explains that there are three key drivers behind the demand for lower arsenic content spanning economics regulatory constraints and social barriers “It is simply getting more di cult to sell concentrates with arsenic in them and miners pay a a a higher penalty for trying to do so It simply makes economic sense to nd a a a a cheaper way of dealing with those contaminants “The other issue is is that some mines won’t go ahead without a a a a solution because they don’t want concentrate that is potentially so high in arsenic that that they won’t nd a a a a a buyer that’s a a a a a regulatory hurdle
