Chilean-Romanian mining company Coemin has submitted to environment authority Conama an environmental impact declaration on the expansion of its Cerrillos plant in northern Chile, Conama's environmental impact evaluation system SEIA reported on its website.
The US$10mn expansion would take Cerrillos' ore treatment capacity from 65,000t/m to 220,000t/m. The plant treats ore from the Mina Carola copper mine, owned by SCM Carola.
The expansion would involve the introduction of new technology and equipment, changing the current operation system of the plant.
Cerrillos is located 30km south of Copiapó, in Chile's Region III.
