In this issue:
- Insider view helps improve feedwell design: a better understanding of the physiochemical workings at play in the often murky depths of a thickener’s feedwell has helped one of the world’s leading thickener suppliers make what could be the first significant design change to these crucial units in more than a decade.
- Sulfidic waste offers hidden mineral wealth: research is mapping the way for mining companies to exploit hidden mineral wealth in tailings using simple separation processes.
- Direct route solves metallurgical challenge: international company Baja Mining is planning to use a direct solvent extraction system developed through the Perth-based Parker Centre to help recover copper and zinc from its El Boleo deposit in Mexico.
- Bell rings on coal congestion: a prototype on-line alarm system that uses acoustic emissions to monitor the performance of dense medium cyclones has been successfully trialled at a Hunter Valley coal plant and is now ready to move to the commercial stage.
- On-the-spot analysis offers fast results: a recently developed technique that uses lasers to provide an on-the-spot analysis of elemental composition has the potential to save mining companies both time and money.
