9 Ore Deposits and Economic Minerals – Mineralogy

9.1.3 Mineral Deposits, Ore Deposits, and Mining. A mineral deposit is a place in Earth’s crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse ...

Mining - LKAB

Underground mining. Ore is extracted from LKAB's underground mines by means of sub-level caving. This mining method is based on creating cavities in the orebody through drilling and blasting, and allowing the ore to fall down to underlying levels by means of gravity, from where it is transported onwards by train or loader.
