FAQ
Frequently Asked Questions
No. Ore dressing is the physical/mechanical preparation of ore to concentrate valuable minerals. Smelting is the subsequent chemical process that extracts metal from the concentrated ore.
Primarily mining, metallurgy, geological engineering, and industrial chemistry.
No, it's a highly specialised technical term rarely encountered outside specific professional contexts.
They are largely synonymous in modern usage, though 'mineral processing' is sometimes considered broader, encompassing non-metallic minerals as well.
