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.

Jun 11, 2021 There is no exact way of knowing where the ore will be. You will have to start digging channels into the ground. Sometimes iron is found directly underneath limestone, but that isn't always the case. The best way to start mining is to dig two layers deep and start building conventional mineshafts in different directions. You will need to support the mines with beams and pillars.

MINING. MINING AND MINING RESOURCES Although there had been attempts for over a century to establish small-scale mining in Jamaica, the present well-established mineral industry of Jamaica only dates back to 1952 when the export of kiln dried metallurgical bauxite ore was started. This was shortly followed by the export of alumina.
