Electroflotation of chalcopyrite fines with sodium diethyldthiocarbamate as collector

Abstract

Electroflotation tests were conducted with a chalcopyrite fines-sodium diethyldithiocarbamate system with normal variables such as effect of concentration, pH of the collector and conditioning time, separately with oxygen and hydrogen bubbles generated electrolytically. Studies were attempted to check the effect of pH changes and electrolyte gases on the surface products. The surface products were extracted with carbon tetrachloride and analysed by UV-visible and I.R. spectrophotometric methods. It was found from the results that the qualitative nature of the surface product was unaffected by the above parameters.
