| Hatch studies water recovery at Escondida mine in Chile Canadian-based Hatch was recently retained by BHP Billiton Base Metals to execute a prefeasibility study at the Escondida copper mining facilities in northern Chile. The study will examine ways to improve water recovery from the tailings. BHP Billiton commissioned the prefeasibility study when a long-term mine production plan revealed that the current supply of fresh water will not be able to meet the estimated water requirements of 2,900 litres per second. Hatch Santiago will lead the project. It is scheduled for completion in July 2008. write your comments about the article :: © 2008 Construction News :: home page |
