Great Australia Mine – CIL Upgrade, Gravity Circuit and 2t Modular Pressure Zadra Elution Plant

Como Engineers undertook three related projects at the Great Australia Mine: the CIL Upgrade Project, the Gravity Circuit Project and a modular 2T Pressure Zadra Stripping circuit.

CIL Upgrade Project: The project upgraded the existing copper flotation plant to a gold CIL plant. Works included flowsheet design; refurbishment of the existing crushing, grinding and classification circuits; construction of 8 off leach/CIL tanks; supply and installation of tank agitators, mechanically wiped interstage screens, and vibrating trash, loaded carbon and carbon safety screens; a cyanide mixing, storage and dosing system; and a cyclone tower extension for future gravity upgrade.

Gravity Circuit Project: The project integrated a new gravity circuit into the existing grinding and classification circuit. Works included design, fabrication and installation of two floors into the cyclone tower, which was extended during the previous CIL upgrade; supply and installation of a vibrating gravity screen, Knelson concentrator, Wilfley table and secure working area; and supply and installation of all piping and electrical.

Pressure Zadra Stripping circuit: Como Engineers designed, fabricated, constructed and commissioned a new modular 2T Pressure Zadra Stripping circuit with Carbon Regeneration Kiln.
