Mineral Science experts

Dr Aleks Nikoloski

Hydrometallurgical treatment of metals and minerals and extractive metallurgy

Dr Aleks Nikoloski is an expert in the electrochemistry of leaching and the reduction processes used in the hydrometallurgical treatment of metals and minerals.

He has significant experience in the metallurgical process development using pilot plant scale textwork, and investigates the kinetics and thermodynamics of metallurgical processes for the treatment of non-ferrous metals, in particular nickel, cobalt, copper, gold and the platinum group metals.

Dr Nikoloski teaches extractive metallurgy and supervises postgraduate research students at Murdoch University.

Dr Gamini Semanayake

Mineral Science and hydrometallurgical processes

Dr Gamini Semanayake is a senior lecturer in Mineral Science at Murdoch University and an expert on the application of ionic activity data and speciation analysis to hydrometallurgical processes and the rationalisation of the thermodynamics and kinetics of the leaching of minerals and recovery of metals.

Dr Semanayake’s project include: Catalysts for reactions of hydrometallurgical importance; high temperature hydrometallurgical thermodynamics; beneficiation and utilisation of red mud residues from alumina processing; mechanisms of gold leaching; ion salvation thermodynamics and applications, and; atmospheric leaching and recovery of metals from nickel laterite ores.
