Digging Deeper: Mining Methods Explained | Anglo American

Large scale mechanised mining methods we use include: longwall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub-level caving, where levels of the ore are blasted by explosives; and; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity.

Operations | Anglo American – Kumba Iron Ore

Sishen mine has sufficient reserves to sustain a 14-year life of mine. The bulk of our iron ore production comes from Sishen mine, with most of it being exported. We mine by opencast methods and then transport the ore to the beneficiation plant where it is crushed, screened and beneficiated.

Evidence of the impacts of metal mining and the effectiveness of mining

Background Mining can directly and indirectly affect social and environmental systems in a range of positive and negative ways, and may result in societal benefits, but may also cause conflicts, not least in relation to land use. Mining always affects the environment, whilst remediation and mitigation efforts may effectively ameliorate some …

Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine. Excellence in planning, scheduling and quality control

Iron Ore Supply Chain: From Mining to Steel Production

Iron ore is a crucial raw material for the global steel industry, and its supply chain is a complex network that involves multiple stakeholders and activities. The iron ore supply chain begins with the mining of iron ore, which is then transported to processing plants for beneficiation and further refinement. The refined iron ore is then transported …

Selection of new appropriate mining method: case of Boukhadra iron ore

The selection of the adequate mining method is the cornerstone for mine planning and design. This selection depends on geological, geotechnical, economical, and environmental parameters.

Iron ore extraction techniques

Iron ore was won by drilling and blasting (Figure 7.1).As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as "dogger") allowing mine drivages to be self-supporting. However, he states …
