Eurus Mineral Consultants

Eurus Mineral Consultants (“EMC”) was formed in early 2002 by Martyn Hay and operates as a one-man company. EMC offers specialist milling and flotation consulting services to the mining industry world-wide. 

The company has developed and uses SUPASIM®, a proprietary flotation simulation program and an empirical mill sizing methodology and also maintains a large database of milling and flotation operations as well as associated laboratory and pilot test data to characterise ores and predict plant performance. 

To date SUPASIM® has been used to simulate and design nine operating float plants from laboratory data only.  SUPASIM® has also been used to simulate and optimise over forty other plants covering Platinum Group Metals, Base Metal Sulphides, Pyrite/Gold, Industrial Minerals, Furnace Slag, Tailings Dams and Cassiterite. 

EMC has also developed commercially available software, KinCalc®, which determines flotation kinetics from laboratory and pilot rate test data, graphs test data and results, produces summary tables and stores all data and kinetics in either Access or SQL. To upgrade functionality, KinCalc is currently being reprogrammed in Mathematica (
