In mineral processing, we treat minerals, not assays. Assays are a guide to how the minerals are concentrating; mineralogy provides the fundamental information as to what we are processing. It is from the mineralogy that we derive processing strategies such as grinding and regrinding, and electrochemistry for flotation.
On the modern Process Mineralogy platform, several quantitative mineral measurement tools are available, such as QEMSCAN, MLA, and the TIMA. When teamed up with a modern microprobe such as the CAMECA SX-100, powerful compositional information is obtained that informs the project of variations in the mineral composition. This variation influences and changes the optimal flotation domain for that mineral.
