As a result of significant environmental effects posed by acidic mine water on ecological systems, a multitude of technologies have been developed and applied for the remediation of acid mine drainage (AMD). Traditionally, alkaline materials have been used in active and passive initiatives toward the treatment of AMD.
One example can be found in industrial-scale experiments conducted by Helmholtz Institute Freiberg for Resource Technology (HIF) 5 based in Germany. This group demonstrated how water usage can be optimized in the extraction of fluorite, an important raw material used in the smelting of iron and aluminum extraction.

Iron Duke and Iron Baron, Arrium, Australia; Bhushan Power and Steel, India; Roy Hill Iron Ore, Australia; Christmas Creek, FMG, Australia; With teams located in major mining regions around the world, we can work with your local team to supply iron ore beneficiation solutions across all stages of the project lifecycle.
Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and …
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 …

For some unknown reason, this technology lagged in the iron industry for an additional fifty years. From the time in which the first serious demands for the substitution of coal for charcoal came about, almost 200 years elapsed before coal could be used effectively in the iron production process. The combination of the difficulty of using coal ...

The Sishen mine is located 30km away from the town of Kathu in the Northern Cape Province, South Africa. It is one of the largest open-pit mines producing iron ore in the world. Mining at Sishen is carried out as part of Anglo American's Kumba Iron Ore operation. The mine accounts for the majority of Kumba's iron ore production.
Companies across the world have raised tens of millions of dollars to test asteroid-mining technologies. Some say the idea is a prohibitively expensive, far-fetched fantasy. But 38-year-old ...
Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface …
This report compiles information on selected technologies for treatment of mining-influenced water (MIW). The report includes those technologies that are used to treat MIW for which information was readily available. It is not a …
The mining industry is at a tipping point where sustainability and decarbonization are top items on CEOs' agendas. To achieve a 1.5°C climate-change target by 2050, the mining industry will need to reduce direct CO 2 emissions to zero. Encouragingly, our analysis shows that solutions to decarbonize the majority of …

Portland cement – the most common type of cement used around the world – is commonly used in underground mining to shore-up shafts to prevent collapses. Although very effective in sustaining shafts, …
Rio Tinto plans to raise output by 16% at the Gudai-Darri mine, its newest iron ore mine in Western Australia, part of its plan to bring the company back to record production levels by 2025.. The Anglo-Australian mining giant is the biggest iron ore producer in the world, and will increase production at the Pilbara region mine by seven …
Iron smelting and forging technologies may have existed in West Africa among the Nok culture of Nigeria as early as the sixth century B.C. In the period from 1400 to 1600, iron technology appears to have been one of a series of fundamental social assets that facilitated the growth of significant centralized kingdoms in the western Sudan and along …
