After mining the rocks in a crude form, the minerals are sorted for quality both manually and via processing machines. Thereafter, they are downsized in a variety of sizes, depending on the requirement of a customer's manufacturing process:
1. Lumps: 50 - 150 mm
2. Chips: 1 - 5 mm
3. Powder: 43 microns (325 mesh) - 500 microns (30 mesh)
