Stirred tank with ferrous ion as energy source

Gormely and Branion, 1989

20-L stirred tank. Model system with 0.5 to 20% w/v glass beads. The density r of the suspension accounts for the influence of the solids

Liu et al. 1988

7-L stirred tank with 15% w/v chalcopyrite concentrate and air enriched with 1% CO2

Acevedo et al. 1988

7-L Pachuca tank with 15% w/v chalcopyrite concentrate and air enriched with 1% CO2

Acevedo et al. 1988

18-L stirred tank, model system with 0 to 40% w/v solids

Mills et al. 1987

4-L air-lift column with 0 to 24% w/v gold concentrate

Canales, 1999

14-L rotating drum reactor with 50% w/w gold concentrate

Herrera et al. 1997
