With new LASTA MC Filter Presses, gold mine will recover 99% of residual gold in waste filter cakes with plans to increase processing to 30,000 tons per day.

Micronics, manufacturers of filter presses, filter plates, and filter cloths used for various applications including, gold, silver, and mineral processing, has been awarded a US$14 million contract to provide LASTA MC Filter Presses to a north American mining partner. With the LASTA MC presses, the mine will begin processing 10,000 TPD (tons per day) with short term plans to increase to 30,000 TPD - a 200% increase in production.

The LASTA MC filtration process includes the removal of cyanide and a 99% residual gold recovery from the filter cake before tailings disposal. This new dewatering process is expected to yield greater returns for the mine; expansion will be completed in 2011. Micronics has already supplied a US$1.5 million contract to the mine for Merrill Crowe process using semi-automatic filters and is negotiating a long-term technical relationship.

"With the addition of the LASTA presses, the mine will be able to greatly add to its processing. To process 10,000 TPD is good; to increase that to 30,000 tons is extraordinary. By partnering with Ishigaki, we've been able to expand our product line further into the global mining market and other industries as well, including chemicals and waste remediation."
