of sulfuric acid. Considering the comprehensive results, the flotation index of new
scheme is as good as that of HAPP.
Conclusions
In this research, an environment friendly and cost-effective approach was developed
for the beneficiation of high sulfur lead–zinc sulfide ore from Fankou mine, Guangdong Province, China. The closed circuit flotation generates concentrates with Pb
grade of 60.84%, recovery of 82.60% and Zn grade of 56.22%, recovery of 95.26%,
S grade of 46.78, recovery of 64.47 by new method. Both the reagents’ costs and
power requirements were minimized, resulting in 4.5 million RMB annual savings
for the Fankou mine.
