World Leader in Calcined Magnesia

Causmag International, a subsidiary of Orind Australia Pty. Ltd. has been mining and manufacturing high grade magnesium oxide products for use in agriculture, animal health, industrial and pharmaceutical processes, for over 60 years.

Causmag magnesium oxides are derived from high purity natural magnesites from our mining operations at Thuddungra near Young, NSW Australia. The magnesites are cryptocrystalline with small crystallite size – high density and very high purity.

Controlled calcination and processing of this superior feedstock with tight control at all stages ensures top quality magnesia products, with the following desirable chemical and physical characteristics:

  • Very high MgO content – with corresponding low impurity levels.
  • Consistent chemical and physical properties.
  • High bulk densities, leading to reduced demand on storage and handling.
  • High chemical reactivity.

Causmag magnesias are available in a wide range of particle size from granular to superfine powders. All products are packaged to the highest standards, providing maximum protection and positive grade identification.

We currently export our products to USA, Europe, Asia, New Zealand and South Africa at competitive prices.
The diversity of particle size enables Causmag products to be employed in an ever widening variety of applications. Several grades of Causmag MgO and MgCO3 have been developed and tailored for specific agricultural and industrial purposes.
