Project Details


The project involves the construction of a new concentrator plant at the Toquepala mine to expand the processing capacity of the existing plant. The Toquepala concentrator expansion is a project that will not require the use of additional fresh water. Water supply will be covered by high efficiency thickeners to recover water from the tailings. Once in operation, the Toquepala expansion will increase annual production capacity of copper, and will also increase molybdenum production. The project also includes increasing storage capacity of the Quebrada Honda tailings dam from 732Mt to 1,876Mt.
