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 carefullyoptimiseden-USFroth flotationFlotation reagentsFlotation activatorsFlotation collectorsReagents in calamine zinc ores flotation.Artigo publicado em periodicoO periódico Minerals Engineering concede permissão para depósito do artigo no Repositório Institucional da UFOP.
