RE: RE: RE: RE: RE: RE: RE: OR GETTIN U TO FOLLOW anybody knows what means adding a roaster?
normally the copper concentrate wil be shipped to a smelter for sale.
but this concentrate has to be burned in a furnace (roaster) to transfer the sulphide into oxide. the S and As will be present as gas phase (SO2 etc) that will pose environmetal challenege.
also consider the cost to add roasting stage.
