Pneumatic Flotation Leachox™ Refractory and Sulphide Gold Process MMS Cyanide Destruction Process (MMS CN-D) Imhoflot™ Pneumatic Flotation Plants(General Information Release January 2003)

MMS recently commissioned the 600tph iron ore reverse flotation plant for the CMH concentrator at Huasco, Chile.

Maelgwyn MS and joint venture partners Ingenieria de Minerales (IDM) of Antofogasta supplied and installed Imhoflot equipment for the CMH iron ore concentrator in Huasco, Chile. The twin stream flotation plant incorporates six IMF 45 cells and treats 600 t/h of magnetic separator concentrates for removal of silicates. Test work indicated that Imhoflot technology was the most successful option to achieve final SiO2 levels of less than 1,5%. The plant incorporates a self-contained PLC and operator interface to allow full control of start-up, shutdown, flow rates and individual cell variables. Commissioning and performance testing were concluded successfully in November 2002.

Compania Minera Huasco (CMH) is a company owned by Compania Minera del Pacifico SA (CMP a 100% subsidiary of CAP SA) and MC Inversiones (a Mitsubishi group subsidiary).
