Simulus Laboratories worked with Altech Chemicals to define and develop their process for production of high purity alumina from their kaolin feed stock mined at Meckering in Western Australia. The process involves initial heat treatment, hydrochloric acid leaching, intermediate precipitation with HCl gas, intermediate purification and final product calcination, washing and jet milling. The flowsheet has been developed with an array of batch testwork and mini-plant piloting of the key unit operations.

Simulus Engineers also completed the multidisciplinary engineering design for the bankable feasibility study.
