Deposit THE FIRST PHASE OF THE ILO REFINERY PROJECT, WITH A DESIGNED ANNUAL CAPACITY OF 150,000 MTPY OF CATHODE COPPER WENT ON STREAM IN 1977. IT HAD OPERATED AT PARTIAL CAPACITY SINCE ITS INAUGURATION IN SEPTEMBER 1975. THE ANODE PLANT WAS DESIGNED AND BUILT BY MINERO PERU AND THE ELECTROLYTIC REFINERY WAS BUILT ON A TURNKEY CONTRACT BY MITSUI FURUKAWA OF JAPAN. THE INSTALLATIONS OF THE REFINERY WERE BUILT AT A TOTAL COST OF $56 MILLION. THE TREATMENT OF ANODE SLIMES YIELDS BYPRODUCT GOLD, SILVER, SELENIUM, TELLURIUM, AND BISMUTH. THE REFINERY IS DESIGNED TO BE EXPANDED BY AN ADDITIONAL 150,000 TO BE ABLE TO ACCOMMODATE THE FULL BLISTER PRODUCTION FROM THE ILO SMELTER OF S.P.C.C. FOR A FULL PROCESS DESCRIPTION OF THE REFINERY, SEE THE E/MJ ARTICLE NOTED IN THE BIBLIOGRAPHY. THE ILO REFINERY, WITH AN ORIGINAL INSTALLED CAPACITY OF 150,000 MTPA REFINED CATHODES, WAS EXPANDED TO 175,000 MTPA IN 1989, AND TO 187,000 MTPA IN 1991. IN APRIL OF 1993, MINEROPERU ANNOUNCED THAT THE ILO COPPER REFINERY WAS TO BE SOLD TO PRIVATE INTERESTS. IN APRIL OF 1994, SOUTHERN PERU COPPER CORPORATION WAS NOTIFIED THAT IT HAD SUBMITTED THE WINNING BID AND RECIEVED OWNERSHIP. THE BID WAS NET CASH OF $65 MILLION (SUBJECT TO FINAL CLOSING ADJUSTMENTS) AND $20.3 MILLION THAT WOULD GO TOWARDS INCREASING THE CAPACITY AND IMPROVE EFFICIENCY OVER THE NEXT FEW YEARS.
