Iron ore - Wikipedia

Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite

01/01/2015  As stated in the previous sections, the mining of iron ore, at both the surface and underground, ceased in the United Kingdom toward the end of the twentieth century, not only because of the general poor quality of the ores leading to high costs of production (from the deep mines) but also due to the environmental impact of surface mining, a problem that has dominated all attempts to mine minerals by opencast methods in the densely populated United Kingdom. Additionally, iron ore mining

Haematite deposits of Cumbria - Earthwise

It seems highly probable that haematite was worked for iron ore in Cumbria in pre-Roman times, though the first documentary records date from the 12th century. The 19th century witnessed the peak of production before large-scale mining ended in south Cumbria in 1968, and in west Cumbria in the late 1970s. Small-scale production for the manufacture of pigment continued until 2006 from shallow

Talk:Iron ore - Wikipedia

If we limit the discussion to iron ore resources and reserves, the message can be incredibly misleading as new resources and reserves are identified every year. For example, the "pilbara depletion" section of the article says that the pilbara has demonstrated resources of 24 billion tonnes of iron ore, and it could all be mined out within 50 years. This ignores the fact that long before it would be mined out, new

Iron mining Industrial History of Cumbria

The resultant ore bodies formed large flats (bodies of solid ore) which connected with the bedding planes of the host rock, irregular bodies occurring as large swellings within the vein, or true veins or faults whereby the haematite solution followed the lines of weakness. the miners were forever optimists for, just ahead of them, the vein could open out into a new and profitable shoot of ore.
