25.2 Extracting ores Mining of mineral resources Siyavula

Various methods are used to locate potential sites for mining. Ore is removed from the crust by mining, either on the surface (open pit mining) or underground (shaft mining or room and pillar mining). Some minerals can be used in their natural form, for example sand in the building industry, phosphate rock for fertilisers and diamonds in jewellery.

Iron Ore Mining Techniques Metal Extraction

2021-7-15  Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

ICMM Operating mines

Exploration. Before a mine is established a long process of metal and mineral exploration is required. Advanced scientific techniques (eg geochemical analysis of the Earth’s crust or airborne surveys to measure magnetic, gravitational and electromagnetic fields) are used to help determine whether a location has a sufficient mineral deposit to warrant mining.

Chromite mining - The Oregon Encyclopedia

A few larger mines hired workers and provided room and board. Most operations were small, and many investments found little return. When the grade of the chromite was low, mills were needed to concentrate the ore; miners often converted mills used for gold.

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 ...
