Mexico’s Top Silver and Lead Producer Successfully Commissions SONARtrac® System

CiDRA Minerals Processing Inc. announced the successful commissioning of

the SONARtrac system on a dewatering line 302m underground. Industrias

Peñoles, Mexico’s second largest silver and lead producer, selected

CiDRA’s SONARtrac system for their Naica Mine, a lead, zinc and

silver mine located in the municipality of Saucillo.

CiDRA and Techflow, CiDRA’s Mexican representatives, successfully

installed the system overcoming several challenges beyond the depth of

302m. Those challenges included dealing with scaling in the line,

difficult flow rates, water temp of 60C, as well as the large meter size

(24 inch) needed to accommodate the line. These challenges would make it

impossible for other conventional flow meters to be installed, and the

reason the SONARtrac system was chosen. The company has now

purchased three more SONARtrac systems for additional use on

their process water lines.

The Naica mine is 100% owned by Peñoles, and is located in Saucillo,

Chihuahua. The mine’s installed capacity is 950 thousand tons/year

milled, with reserves at +89.6%. Peñoles has owned extraction rights to

this mine since 1964, and the mine is currently the second largest lead

mine in Mexico. In 2011, production of lead and zinc contents totaled

15,495 tons (+2.4%) and 13,048 tons (+17.3%) due to better ore grades

and recoveries, helping Naica contribute 24.8% and 7.2% of total

production on those metal contents respectively.

CiDRA’s SONARtrac flow technology is a new class of industrial

flowmeter, utilizing measurement principles that are distinct from all

other flowmeter technologies operating in the mining industry. SONARtrac

non-intrusive flow monitoring systems do not make contact with the

fluid and can be removed and reinstalled without process interruption

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.

Vegas on September 24-26, 2012.
