Deep Mining Of Iron Ore

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs

Dec 09, 2021 We all know the old rule of thumb. Dig down to about Y=11 and build a branch mine with two rows of blocks between each tunnel. That’s because, in the old system, diamond, redstone, iron, lapis lazuli, and gold were all found in significant quantities at this one level. There was no variety in block height aside from the much newer copper, which was more likely to be

The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. What is underground mining? The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining

The ore lenses can contain a very low percentage of sulphides up to 100% sulphides. Pyrite (iron sulphide) is the dominant sulphide, although sphalerite (zinc-iron sulphide) is locally abundant. Chalcopyrite (copper-iron sulphide) is common. Pyrrhotite (iron sulphide) is also present locally, as well as galena (lead sulphide)
