Gold and PGM Deportment Studies
A Gold, Platinum and Palladium Mineral deportment study helps define the recoverability index at the exploration phase for economic evaluation, technology risk control, flowsheet development and process optimisation.
The speciation and morphologies of the minerals are determined at the AMI with the specialised, unique sample preparation procedures with ultra-high resolution TESCAN TIMA SEM-based automated mineralogy system.

Define your recoverability index
The information is used for:
- Ore body knowledge
- Geometallurgical parameters
- Process selection
- Recovery prediction
- Plant optimisation
- Reduce the technology risk
Other factors will be concerned for predictive recoverability such as slow-dissolving, CN and O consumer, coating and rimming, reagent and preg-robbing
Particle Classification for Gold
Using high-resolution (BSE) images generated by the TESCAN TIMA, mineral phases are identified and classified.
