Las Bambas is third largest copper mine in Peru.

Due to safety concerns, Las Bambas will be unable to continue copper production as of 20 April 2022 (Peru time). MMG remains committed to working closely with the Government of Peru and the community members to deliver its commitments and to engage in transparent and constructive dialogue with the aim of reaching an enduring agreement.

MMG welcomes the agreement by the communities to cease protest activities and to participate in a Government-led dialogue process for a planned 30-day period commencing on 15 June.

Production at site and concentrate transport is expected to recommence on 11 June 2022 (Peru time).

Deposit Type

  • Skarn
  • Porphyry

Source: Source p.33-34

Summary:

Las Bambas is located in a belt of Cu (Mo-Au) skarn deposits associated with porphyry type systems situated in south-eastern Peru. This metallogenic belt is controlled by the Andahuaylas-Yauri Batholith of Eocene- Oligocene age, which is emplaced in Mesozoic sedimentary units, with the Ferrobamba Formation (Lower-to-Upper Cretaceous) being of greatest mineralising importance. The porphyry style mineralisation occurs in quartz-monzonite to granodiorite rocks. Hypogene copper sulphides are the main copper bearing minerals with minor occurrence of supergene copper oxides and carbonates near surface. The intrusive rocks of the batholith in contact with the Ferrobamba limestones gave rise to contact metamorphism and, in certain locations, skarn bodies with Cu (Mo-Au) mineralisation.


Mining Methods

  • Truck & Shovel / Loader

Source: p.37, 46, 50

Summary:

Mining of the Las Bambas deposits is undertaken by open pit method, which is expected to continue throughout the life of mine. Large scale mining equipment including 300 tonne trucks and 100 tonne electric face shovels are used for material movement.

The mining method selected for the Las Bambas operation is open cut mining, which enables bulk mining of these large low to moderate grade mineral deposits that are outcropping to sub-cropping. Three deposits, Ferrobamba, Chalcobamba and Sulfobamba are each mined in separate open pits. Mining is by way of conventional truck and shovel operation. This method and selected mining equipment are appropriate for these deposits.

In the pit, the minimum mining width is 70m; the Selective Mining Unit (SMU) has been set at 20m x 20m x 15m.


Crushing and Grinding


Processing

  • Flotation

Source: Source

Summary:

The metallurgical process is a conventional froth flotation concentrator and thickener to produce two separate Cu and Mo concentrates and is appropriate for the style of mineralization.

Metallurgical Copper concentration process comprises the following activities; Crushing, Grinding and Flotation, producing copper and molybdenum concentrates. Copper concentrates contain gold and silver as byproducts.

The ore is crushed and transported on a 5.5-kilometre overland conveyor to a conventional flotation plant where copper concentrate is produced, then to a molybdenum plant for further processing. Concentrate is then transported by truck and rail to the Port of Matarani in the Arequipa region, where it is shipped to customers worldwide.
