This study was performed to determine the effect of tannic acid (TA) on hydrophobicity of galena using Taguchi’s design of experimental methodology. Roles of metal ions, dithiophosphinate (DTPI) concentration, and conditioning time on TA-galena interaction were tested by contact angle measurements. Results were evaluated by analysis of variance (ANOVA) test. DTPI was found to be the most effective...

Przeprowadzono badania procesu flotacji bez użycia kolektora siarczkowej rudy ołowiu i cynku, stosując siarczek sodu. Badano wpływ stężenia siarczku sodu, czasu kondycjonowania oraz pH zawiesiny flotacyjnej na parametry wzbogacania cynku i ołowiu. Określono także wpływ czyszczenia koncentratu na proces wzbogacania. Otrzymane wyniki z flotacji bez użycia kolektora porównano z wynikami, jakie uzyskano...
