Our productive process from start to finish

The Pampa Camarones Cathode Plant is designed to process 60.000 ton/month of ore, which is crushed and then placed in on-off leach pads, on which an acid solution irrigation system is incorporated for its leaching. The solution percolates and is stocked in ponds, and then transferred into the SX plant to be processed, in order to generate 700 ton/month (8.400 ton/year) copper cathodes in the EW plant. The material already leached,

is removed from the heap leach and transported to the ripios dump for its final disposition.

The Pampa Camarones Cathode Plant Project considers the electric supply through a 23 kV electric transmission line. While the water supply was considered by a seawater adduction pipeline.

Crushing Plant

This section is in charge of delivering the ore from the mine, crushed to a uniform granulometry, to the leach pads. It consists of a primary jaw crusher, a cone crusher that acts as a secondary crusher and an agglomeration drum. Each of these units are fed by hoppers, conveyor belts and screens designed for this purpose.

Heap leaching

In this section, the agglomerated ore from the crushing area is placed in leach pads of an average height of 2.5 to 3.0 meters which are irrigated with solutions acidulated with sulfuric acid for a period of 90 days. In this period an average recovery of 82.7% of the CuT is obtained. The irrigation can be done with drippers or sprinklers. The solutions depending on their concentration are directed to the different operation ponds.

Solvent Extraction (SX)

The installation includes an operation circuit consisting of a copper-rich aqueous solution pond called PLS, an organic regulator tank, six mixer-settling tanks (E1, E2, E3, L1, L2 and S1), two post-decantation ponds of refine and a treatment system of waste from the operation of the plant.

Electro winning (EW)

The Electro winning (EW) plant is equipped with 50 cells of polymer concrete, divided into 2 sections with 25 cells each, arranged in a back-to-back configuration.

The cells are electrically connected in series, containing 31 cathodes and 32 anodes each, at a distance of 100 mm between cathodes. The electrodes used are permanent 316L stainless steel cathodes and insoluble anodes Pb-Ca-Sn alloy. The electric direct current supplied to the plant is through two identical rectifiers 12,000 [A] each, connected in parallel, having a total available of 24,000 [A] for the operation. The final product obtained, Cu cathodes, are packaged in bundles and sold.
