In Brazil, the application of flotation for gold-bearing ores started in the 1980s (Araujo and Peres, 1995). There are three important Brazilian plants using flotation to process gold ores (Monte et al., 2002). At the São Bento plant, gold and pyrite are floated into a bulk concentrate for further processing by bacterial and pressure leaching.
