Some 4,000 metres (13,000 feet) above sea level in central Chile’s Andes mountains, Minera Lumina is devel-oping a new copper and molybdenum mine and processing plant. FLSmidth has been awarded the crushing, grinding and flotation portion of the mineral processing plant.
When completed by 2013, Minera Lumina’s Caserones plant will process around 105,000 tpd of primary and secondary copper ore extracted from an open pit mine. The ore bodies are low grade and the client has selected technologies allowing economical utilisation of these mineral resources.
Complete flow sheet saves costs and time
In May this year, FLSmidth signed a contract to provide crushing equipment (primary and cone crushers), grinding equipment (SAG mills, ball mills and cyclones) and flotation and thickening equipment. The contract includes not only design and engineering but also equipment supplies.
Once detailed engineering is complete and final discharge points are defined, orders for the conveyor and feeder belt systems as well as pumps will be added.
Consequently, FLSmidth will be supplying all the primary processing equipment. Group CEO Jørgen Huno Rasmussen comments: “The value to the customer lies in the fact that FLSmidth can supply the complete flow sheet of equipment and deliver the engineering for the complete process within weeks of order placement. This reduces plant engineering costs and saves time.”
Minera Lumina Copper Chile is jointly owned by Nippon Mining & Metals Co., Ltd. and Mitsui Mining & Smelting Co., Ltd. The company is also developing the Quechua copper project in Peru’s Cuzco region.
