Description

The beryl zeta potential in microelectrophoretic cell is studied in the presence of neutral electrolyte, cations of calcium, magnesium and iron. The petroleum sulfonate is used how collector in Hallimond tube. Hydroxy complex of metallic cations seems activate the ore and precipitates of colloidal metallic hidroxies seems lower him when added to the mixture. (M.A.C.)

Abstract (Portuguese)

Estuda-se o potencial zeta do berilo em celula microeletroforetica na presenca de eletrolito indiferente, cations calcio, magnesio e ferro. Utiliza-se sulfonato de petroleo como coletor, em tubo de Hallimond. Conclue-se que hidroxo-complexos de cations metalicos adicionados ao sistema parecem ativar o mineral, enquanto hidroxidos metalicos coloidais precipitados agem como depressores. (M.A.C.)
