    Valves for autoclaves high pressure acid leaching (HPAL)

    One of the typical processes for autoclaves is high pressure acid leaching (HPAL), which is often used for the extraction of nickel from laterite ore bodies but can also be applied in copper and cobalt production. The two major benefits of HPAL are the quickness of the process and high recovery rates compared to conventional leaching methods.

    AUTOCLAVE LEACHING OF ARSENIC FROM COPPER

    Results are given for autoclave leaching of concentrates and mattes from polymetal semiproduct melts containing arsenic alongside copper. The possibility is demonstrated of selective copper and arsenic leaching into solution. It is confirmed that with autoclave leaching arsenides are broken down better than for natural arsenic containing minerals.
