| Abstract: | Experimental study on a carbonaceous Pb-Zn ore from Yunnan was carried out adopting a sequential flotation method composed of C-selective flotation, Pb-S bulk flotation and separation, Zn-S bulk flotation and separation, lead concentrate and zinc concentrate were obtained successfully, with pyrite recovered as a by-product. Pb grade and Zn grade in the lead concentrate are 47.72% and 4.25% with corresponding recoveries of 48.05% and 0.38%, while Zn grade and Pb grade in the zinc concentrate are 50.27% and 0.72% with a Pb recovery of 94.21% and a Zn recovery of 15.13%. It can be seen the loss of lead and zinc in carbon product is limited. |
