The press release is quoted as saying:
Operation of the pilot plant (see 360° Rotoshoot at the following link: http://www.americanmanganeseinc.com/investor-info/american-manganese-inc-interactive-pilot-plant/) commenced on August 18, 2011 under the direction of Dr. Gie Tan, Director of Hydrometallurgy at Kemetco Research Inc. Operational assistance of the solid/liquid separation section of the pilot plant was provided by Pocock Industrial Inc. (a specialist in solid/liquid separation).
The pilot plant was initially operated in semi-continuous mode to test several different operating conditions such as particle size in the leach stage, flocculent type and dose, and general operating conditions of the thickener and counter current decantation (CCD) circuit for solid/liquid separation. The pilot plant was then operated in continuous mode over 72 hours to test the performance of the leach and solid/liquid separation in steady state conditions.
