Iron Ore Mining Techniques Metal Extraction

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.

It Started With An Idea New Gold Recovery

Present day placer mining uses pans, water and gravity, just like the prospector of 1849, only on a larger scale. This “modern” placer only recovers up to 40% of the gold from every ton of ore concentrate (finely ground ore) as it primarily targets nuggets and flakes of gold. The remaining 60% goes untouched.
