The Itos Chloride Leach Plant For Silver - Two Years Into Production

In late 1995 at the Randol symposium in Squaw Valley, I gave a paper which described the Itos project flowsheet. At that time, project construction was nearly completed and stmtup was close. This paper describes the ltos operation since then. To summa­rize things, startup occurred partially in late 1995 with full start­up of all components in about mid 1996. From then until now, April 1998, the plant has been running at partial capacity and has yet to achieve full production rates.
