How digital innovation can improve mining productivity ...

 · The global mining industry is under pressure. In the short term, falling commodity prices are squeezing cash flow. Looking ahead, many existing mines are maturing, resulting in the extraction of lower ore grades and longer haul distances from the mine face; ore-body-replacement rates are in decline; and new-mine-development times are increasing.

WHERE IS IRON ORE MINED?

Iron ore can be found all over the world, in the form of rocks and other minerals. To be economically viable for mining, iron ore must contain at least 20% iron. Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%.

Developments in iron ore comminution and classification ...

 · Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. About 98% of the mined iron ore is used to make steel either by the blast furnace—basic oxygen furnace (BF-BOF) route—or through the electric arc furnace (EAF) route. The majority of world crude steel is made from the BF-BOF route.

Technology in the Medieval Age

 · A classic mining book, De re metallica (published 1556), showed a variety of pumps, bucket chains, and treadmill devices. In any case, by the year 1500, iron production for Europe was 60,000 tons (Gies & Gies, 1994). This increase in iron reduced its cost and, at the same time, increased the number of tools available, particularly in agriculture.
