Abstract
Selective arsenic extraction from enargite based complex concentrate from
Copper Mine in Bor (Serbia), using sodium hypochlorite as a leaching agent,
was investigated in this paper. The aim was to assess the optimal conditions
for the most efficient arsenic removal from the investigated concentrate,
based on factorial design applied to experimentally obtained data. Five
important factors with three factor levels were used as the input variables
and experimentally obtained arsenic extraction yield was taken as the output
variable. The first and the second final order model equations were obtained.
It was found that the leaching temperature had the strongest effect on the
arsenic extraction. The strongest positive interaction was between the sodium
hypochlorite molar concentration and the stirring speed during extraction.
