From "15/03/07 Market Update – March 2007":

The EAF dust project (Unanderra NSW)
The project remains a strong contributor to our operations. We a currently processing around 1,200 tonnes per month of EAF dust and producing 100 tonnes per month of Zinc Sulphate produced from the dust.
A trial parcel of Zinc Sulphate Monohydrate, suitable for wider application will be produced in March for test work by a major consumer. The parcel will also assist in scoping the appropriate equipment and scale to produce up to 4,000 tonnes per annum of the widely used agricultural, animal feed and mining chemical.
With positive results expected from the trial we intend to negotiate a long term agreement with the EAF dust generator which will be beneficial to both parties.
