:: Metso Continues Crushing Freeport

PT Freeport Indonesia is buying a second Nordberg MP1000 short head cone crusher from Metso Minerals. The 160-tonne crusher will be installed beside the mine's existing MP1000 and the two units will be the major part of a multi-million dollar upgrade of the pebble crushing circuit. The two crushers will process up to 1,500 tonnes/hour of 63 mm x 12 mm pebble rejects from the two Metso SAG mills in the C3 and C4 concentrator grinding lines. The fines from the MP1000s will then be returned to the ball mill circuit via multiple Metso super screens operating in closed circuit. This upgrade will allow the mine's SAG mill concentrators to operate together rather than separately, improving throughput, plant flexibility and operating efficiency. The operation has an average production is 237,800 tonnes of ore a day, is located in West Papua, Indonesia and is a subsidiary of US firm Freeport-McMoRan Copper and Gold.
