Kaolin

Kaolinite is an industrial mineral belonging to the group of aluminosilicates. The term kaolin is used to describe a group of relatively common clay minerals that have an enhanced concentration of kaolinite and are formed through the chemical weathering of aluminum silicate minerals. It is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay).

Kaolin’s commercial attributes primarily revolve around being chemically inert over a wide pH range, as well as its brightness, film strength, whiteness, opacity, gloss, viscosity, low heat conductivity, and low electrical conductivity, which lead to a diversified range of industrial applications.

Toondoon Kaolin

The high kaolinite content of Toondoon’s raw ore, of between 80-90%, presents as Australia’s highest-grade known raw ore kaolin resource held under an approved Mining Lease.

Zeotech’s approved Queensland mining lease (ML 80126) hosts high-grade kaolin near the surface, offering cost-effective, immediate access to direct shipping ore (DSO). This underpins a simple flowsheet and a competitive cost advantage due to the limited beneficiation required to produce high-reactivity metakaolin.

The high alumina content of Toondoon kaolin will allow the ore to be highly suitable to a number of sectors including the white cement industry, refractories, and fibreglass manufacturing.
