2019215 · Abstract In order to investigate the effect of particle size on the flotation performance in the separation of copper-gold-lead, froth products of various size fractions were collected as a function of flotation time. The optimum dosage of potassium dichromate (K2 Cr 2 O 7) and sodium diethyldithiocarbamate (DDTC) were determined by flotation …
