Feat of Clay - unfired clay bricks for sustainable construction

The use of unfired clay as a binder in building materials results in a healthy indoor environment and low environmental impact over the lifecycle of the material. A research project funded by the DTI Partners in Innovation programme showed the technical advantages and practical implications of their use.

Platinum Service - new method for recovering platinum

The process developed for the treatment of ores from the Panton, Western Australia, deposits involves calcining at 400-450ºC. Included in the process is the treatment of the products recovered through flotation, with calcination of the rougher concentrate providing superior results than those obtained from the whole ore.
