Company Profile

Mine: Cooljaloo
Commodity: Titanium Minerals
Ownership: Tiwest Pty Ltd (100%) – (50/50 Joint Venture between Tronox Limited and Exxaro Resources).

Indigenous-named mine Cooljarloo, is around 170km north of Perth.

Grains of valuable heavy minerals were deposited on its shorelines thousands of years ago, where the action of waves and wind formed ‘belts’ of minerals called strand lines.

More than 770,000t of heavy mineral concentrate is produced per year using a dredging operation and dry mining techniques. The dredging operation uses two large floating dredges in a purpose-built pond to pump slurried ore to a floating concentrator to recover heavy minerals from the sand and clay.

The mine uses earthmoving equipment to extract ore from above the water table, feeding it to a land-based concentrator for separation using a hopper and conveyor system. When the ore body is mined the overburden and sands with little mineral content are returned to fill the void; clay residue is pumped to solar drying cells, and the surface is contoured to resemble the original landscape, prior to re-spreading topsoil and seeding for rehabilitation.

The concentrate produced at Cooljarloo is transported south in side-tipping triple trailer road trains to Tronox’s Chandala processing plant where it is separated and further processed.
