Jacobs Engineering Group Inc. (Pasadena, Calif.; has received a contract from Minera Chinalco Peru S.A. to perform a feasibility study for the expansion of its Toromocho copper mining facilities in the Morococha District of Peru.

Officials did not disclose the contract value, but noted that the project is expected to be executed out of Jacobs’ Lima, Peru office with assistance from its Santiago, Chile and Tucson, Ariz. offices.

Jacobs has been working on the Toromocho copper project since 2006. The mine is located at an altitude of 14,700 to 16,400 ft. The current phase of engineering, procurement and construction management is nearing completion. Under the original design, the facility is capable of treating 117,200 ton/d of ore and producing in excess of 210,000 ton/yr of copper, plus byproducts of silver and molybdenum.

Major equipment required for the proposed capacity expansion includes apron feeders, a conveyor system for mill feed, a semi-autogenous grinding (SAG) mill, a ball mill and cyclones, flotation cells, a tailings thickener, and all associated equipment. The existing plant layout allows for the integration of new equipment required for the current expansion.

Minera Chinalco Perú S.A. is a subsidiary of Chinalco Mining Corp. International (CMC). CMC is a company listed on the Hong Kong Stock Exchange. The Aluminum Corp. of China (CHINALCO; Beijing) is the ultimate and controlling shareholder of CMC. CHINALCO is the second largest alumina producer and the third largest primary aluminum producer worldwide.
