TOCHU owns and operates two high quality silica sand mines in Australia. These mines are producing high quality sand by the advanced process plants. ALBANY SILICA SAND is produced by AUSTSAND MINING in Western Australia. This sand has round shape and wide range of size distribution.
To achieve this, silica sand is built up layer by layer until the desired part has been constructed. The layers of sand are selectively bonded using a binder, ensuring stability and flexural strength. This fast process is perfect for manufacturing prototypes or optimizing parts.

Silica sand (also commonly referred to as frac sand) is a crucial ingredient in the oil and natural gas extraction process known as fracking. The hydraulic fracturing ("fracking") process for oil and gas takes a mixture of proppant (usually frac sand), water, and chemicals and injects this mixture into a well under very high pressure.
