Austpac has now received the chemical analyses of samples taken during the Zinc & Iron Recovery Process (ZIRP) testwork program completed in November 2019, including results of the one melt test undertaken by the CSIRO. The preliminary observations are: A pre reduced iron oxide was melted by the CSIRO in an induction furnace and a clean iron with very low impurities was produced. The iron is ideal for making high purity pig iron for use in foundries. The zinc oxide reported with iron oxide to the scrubber dust during the second process stage, and this is now being pre-reduced in a fluid bed roaster. The product will be processed in a second melt test by the CSIRO designed to capture a zinc oxide product for evaluation. The program comprised processing zinc-contaminated furnace dust and spent pickle liquor from a steel mill through of each the first three ZIRP process stages to produce a pre- reduced iron pellet for melting is an induction furnace. The representatives of an Australian steelmaker who observed the operations have provided Austpac with a comprehensive set of analyses of the products from each stage, confirming the results obtained by Austpac. A sample of the pre-reduced iron from the third process stage was melted by the CSIRO in December 2019 to produce the iron product.
