RE: Rio

[pcnisbet]

Which part of pyrometallurgical fuming is unclear? Heck Rio, go back to El Indio as a source and learn something. Both antimony and arsenic are recovered in the same way, so why are you so dense as to assume that either fluid bed or rotary kiln pre-processing of cobaltite could not be used as a method for arsenic removal? That arsenic could then by sold, just as ores from El Indio produced some byproduct Arsenic Tri-oxide. You are not answering the question of why you claim that arsenic can not be recovered suing pyromet from a cobaltite concentrate. Roasting that ore rather than their planned hydromet would be completely feasible, since it happens to be the means used in the past to process ore from the deposit. I recall that you were beeding in the past that their newer methods were a problem, but why is it that you are now condemning previous techniques? Its got arsenic in it, so they can either use the design for hydromet they have cureently worked up and dispose of the ferroarsenides or they can go with the older roasting system and sell the recovered As. Since its pretty obvious that they can do it technologically, why exactly do you think its not possible?
