Gypsum industry news

Australia: Gypsum Supplies has started loading from its newest pit at Lake Cowcowing, Western Australia.

Gypsum Supplies operates at Lake Hillman in Dalwallinu, Western Australia, where the family-run business has been supplying gypsum since 1978 to the industrial and agricultural markets.

"We are continuing to operate out of Kalannie as normal," said registered manager Daniel Nixon. "This pit is of very similar quality and analysis to the Kalannie pit." Naturally-occurring lake gypsum has a medium particle size and unlike synthetic gypsum, is not subject to rapid leaching from the soil profile and reportedly has superior spreading characteristics.

Gypsum is used in the agricultural industry for several reasons. It is used as a low-cost non-acidifying form of sulphur. Kalannie gypsum has 17.8% sulphur. Due to the high returns from growing canola in recent years, demand for gypsum as a low-cost form of sulphur has been strong.
