    Permit agreed for smelter revamp

    Chile’s state-run mining company Enami says that it has received an environmental permit for a new $1.7 billion copper smelter, as part of the modernization of its Hernan Videla Lira smelting facility in the northern Atacama region. The new facility will process up to 850,000 t/a of copper concentrate, and its electrolytic refinery will produce up to 240,000 t/a of copper cathodes for use in electronics, construction and renewable vehicles. Enami says that the modernisation will “ensure profitable and sustainable operations, and practically triple the capacity of the old smelter.”

    Desulphurisation unit installed at Luján refinery

    YPF says that its modernisation of the Luján de Cuyo refinery has taken a step forward with the installation of a hydrodesulphurisation reactor, designed to remove sulphur compounds from diesel fuel by means of a catalytic process using hydrogen. The installation forms part of the refinery’s New Fuel Specifications (NEC) project, intended to produce of fuels with a lower environmental impact. The new reactor was built in Mendoza by IMPSA. With a length of 38 meters and a weight of 456 tons, it was moved from Godoy Cruz to the YPF plant in a logistic operation that involved Vialidad Nacional, Mendoza Police and local authorities. It will now be integrated into the HDS II unit, designed to reduce sulphur content in diesel to 10 parts per million, in line with current environmental requirements. The NEC plan includes new process units, such as H2 II and SE33, the adaptation of existing facilities and the improvement of auxiliary services. The project, already 85% complete, will allow all the diesel oil produced in Luján de Cuyo to comply with the highest emission requirements.

    Operations halted at El Teniente mine

    The El Teniente mine, located in the O'Higgins region, suffered a collapse on 31 July. The collapse in the Andesita sector of the mine is understood to have been as a result of seismic activity that registered 4.2 on the Richter scale. It remains unknown whether the seismic activity was caused by the mining operations or natural activity, according to industry sources. Underground operations are to be halted for an unknown period of time while the open air sector, which represents around 10% of the total production, will remain open, according to industry participants.
