ABSTRACT:
A method and apparatus for high temperature-high pressure acid leaching of sulfide ores is described. The apparatus includes an autoclave having a plurality of pressurized compartments and a water removing-heat removing condenser. Means are described for the introduction of a neutralizing agent directly into the autoclave in order to maintain the acidity of the slurry at a level where substantially all of the iron present in the slurry will form an insoluble iron oxide precipitate. Means are described for removing the gaseous products resulting from the introduction of the neutralizing agent while avoiding contamination thereby of a substantial portion of the oxygen.
