Antamina—70,000 tpd Copper–Zinc Concentrator,
Peru
The concentrator is at a steep and remote site in Ancash,
Peru. The mine is at around 4,300 metres above sea level.
The ownership is composed by BHP (33.75%), Glencore
(33.75%), Teck (22.5%) and Mitsubishi (10%). The plant
started up in 2001, produces copper and zinc concentrates,
also including by-products molybdenum, silver, bismuth,
and lead. The plant design features a single processing line
including SAG and ball mills. The concentrates are trans-
ported in a single pipeline of about 300 km in length to the
port facilities, that includes a filter plant.
OGP1—152,000 tpd Copper Concentrator, Chile
The Escondida Mine is located in the Atacama Desert of
northern Chile at an elevation of 3200 meters above sea
level. OGP1 copper concentrator has been constructed
adjacent to the existing Laguna Seca concentrator plant and
has a nominal capacity of 152 000 tons per day. The plant
design is a single grinding line with one SAG and four ball
mills. The flotation circuit has tank cells, and the thick-
ening process has two concentrator thickeners and three
tailing thickeners. It was started up in 2015. The plant pro-
duces a copper concentrate that is commingled with the
concentrate of Laguna Seca and transported by pipeline to
the port site named Coloso.
