Definitions

  • Molybdenum concentrate sized according to the invention and having 3.3% copper, was leached for seven hours with the lixiviant of example 1 in an agitated, closed leaching vessel containing silica sand particles of about 500 ⁇ m diameter. Of the copper in the concentrate, 96.4% was removed leaving a molybdenum concentrate with 0.14 wt% copper.

Abstract

L'invention se rapporte à un procédé de lixiviation du cuivre et/ou du nickel à partir de sources solides utilisées comme charges au moyen d'un agent de lixiviation contenant du gaz ammoniac et du bisulfure d'ammonium. Ce procédé s'effectue par brassage en présence de solides abrasifs relativement gros et d'un agent d'oxydation, de préférence l'air ou l'oxygène. Les solides abrasifs nettoient la surface d'une charge de solides et facilitent l'exposition constante des nouvelles surfaces en vue d'obtenir une meilleure cinétique de lixiviation et des taux d'extraction maximaux. Le procédé s'applique notamment à des solides contenant des sulfures de cuivre.
