conditioned
with pH modifier (HCl/NaOH), collector and frother. Flotation concentrate
was collected after 2.0 min at air flow rate of 0.5 dm3 min−1. The
flotation froth was scraped every 10 s. Dosages of collector in flotation
were 10−4 M KAX. The conditioning times for adjusting pH and collectorwere
5 min and 2 min respectively. The frother dosagewas one drop
MIBC in all cases. Sphalerite flotation was investigated at different pH.
