The raw materials for our titanium minerals operation come from ancient shoreline sand deposits in the Mid-West region of Western Australia. Millions of years ago, the action of waves and wind formed belts of heavy minerals called strand lines.
Our mineral sands resources are located between Cataby and Dongara, and the current mining operation carries a local Aboriginal name ‘Cooljarloo’. We mine the heavy mineral concentrates using either dredging or dry mining techniques.
Two large floating dredges pump slurried ore to a floating concentrator that recovers heavy minerals from the sand and clay using a series of gravity spirals. At the dry mine, earthmoving equipment feeds ore from above the water table to a land-based concentrator which uses a hopper and conveyor system.
As the ore body is mined, overburden and sands with little mineral content are returned to fill the void and clay residue is pumped to solar drying cells. The surface is contoured to resemble the original landscape, topsoil spread and seeded for rehabilitation.
We transport the heavy mineral concentrate produced at Cooljarloo by road to the Chandala processing plant.
