Resumo: Oxidised zinc ores are traditionallyfloated with fattyamines as collector. The effectiveness of this reagent requires a pre-sulph-idisation stage with sodium sulphide in conjunction with soda ash. Especiallyin the case of calamine ores, a dispersing agent becomes necessary. The collector must be emulsified with a fuel oil and the frother. This flotation system is characterised by the use of verylarge amounts of reagents. The proportion of each reagent in the reagents system must be carefullyoptimised
