Petrolab adds new automated mineralogy capability

  Petrolab, our great friends in Cornwall, UK have been busy over the last few months building up their capability in automated […]

Why use screened fractions in automated mineralogy?

The use of screened fractions at the simplest level is done to provide cleaner data by helping to reduce touching particles and the bias that can be introduced through stereological effects. There are well documented reasons based on the mathematics of converting 2d section images into 3d particles (stereology), which show that if we want to generate a meaningful grain size distribution it should be required that screened fractions are analysed. Stereological corrections work well because they calculate 3d parameters based on a statistically random distribution of particle orientations.

Process Mineralogy in optimization and troubleshooting

I wanted to start our exploration of process mineralogy in the middle of the mine life cycle, with its use in process optimisation and troubleshooting. Why start here you ask? Well process mineralogy can have the biggest impact and finds the most use in this area so it is a great introduction.

The how, what and where of process mineralogy

Welcome to the new addition of the MinAssist blog, to be known as ‘Process Mineralogy Today’. This blog has been developed by MinAssist to promote the use of process mineralogy within operations and as a forum to promote discussion on the most effective ways to achieve this. I encourage you as the readers to comment on the ideas presented and add your comments on where you see process mineralogy going in today’s industry.
