CiDRA wins third expansion contract

CiDRA Minerals Processing, a company offering real time process monitoring equipment, has been awarded, through Bechtel Chile Ltda, its third expansion contract to supply SONARtrac® process monitoring systems to Minera Los Pelambres in Chile, one of the world’s largest copper mines. The SONARtrac systems will provide volumetric flow measurements on critical slurry lines within the concentrator plant, and work integrally within the Los Pelambres expansion project awarded to Bechtel. This contract is part of the ‘Repower 2 Project – Minera Los Pelambres’, scheduled for completion in 2010 which will increase the capacity of the mine’s concentrator from 132,000 t/d to 159,000 t/d.

The project, located in the Andes some 200 km from Chile’s capital, Santiago, comprises two main work sites: the mine area and primary crusher at an elevation of almost 3,000 m, and the concentrator at 1,600 m. A conveyor transports ore from the crusher to the concentrator. Minera Los Pelambres is renowned in the Chilean mining industry for having one of the lowest production costs.

CiDRA’s SONARtrac flow technology is a new class of industrial flowmeter, utilising measurement principles that are distinct from all other flowmeter technologies operating in the mining industry.  SONARtrac non-intrusive flow monitoring systems make no contact with the slurry and can be removed and reinstalled when it is necessary to replace the pipe. As well, SONARtrac systems demonstrate a very stable output in the presence of a variety of ores, and demonstrate superior levels of performance. This passive, sonar-based technology enables measurements of single phase and multiphase fluids, as well as slurries, with the same level of accuracy and performance.
