Use of temperature for diagnosing mixing in the IsaMill
The IsaMill is a recently developed process equipment, first commissioned on a large scale in the early 90s in an effort to help recover values from old mine dumps due to improvements in downstream extraction technologies which could further recover values from ores with fine particles, a technology which was not available before. Also due to depletion of easy-to-extract

Grinding Processes
Grinding is the common collective name for machining processes that utilize hard, abrasive particles as the cutting medium. The grinding process of shaping materials is probably the oldest in existence, dating from the time prehistoric humans found that they could sharpen their tools by rubbing them against gritty rocks.
