The iron ore, coke and limestone are crushed into small round pieces and mixed and put on a hopper which controls the input. The most common ores of iron are hematite Fe 2 O 3, and magnetite, Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke.

If recording Rock Quality Designation (RQD) – this will have already been done for you by a technician. Core boxes for NQ core are built to hole 15 feet – the typical length of a core barrel. We like to measure things in meters so 15 feet of core = meters. So each core box holds approximately meters of core.

21/11/2014 · Iron ore can be mined from all places in the world but to be commercially viable, the percentage of iron in this iron ore needs to be at least 20%. This is because lower iron content in the ore will render all the money and effort exerted in mining the ore from under the surface of the earth a big waste.
Ore can look like many things depending on what grade the ore is if it is a high grade such as Hematite (%) or Magnetite (%) then the ore will have a silver gray type but if the ore has a lower iron content like Goethite (%) or Siderite (%) then it is more likely to look like the type of rock that it was mined from.
