Sep 18, 2011· This modern process for extracting iron ore from taconite and refining concentrate into pellets is a direct result of Dr. Davis' research funded by the IRRRB: First, holes are drilled and the taconite ore is blasted out of the ground.
Iron is extracted from its ore, haematite, by reduction with carbon. This takes place in a blast furnace (named after blasts of air [20% oxygen], heated to 1000 °C, which are blasted into the bottom of the furnace): A mixture of crushed iron ore, coke (an almost pure form of carbon) and limestone is fed into the top of the blast furnace.
In commercial bioleaching, three methods are commonly usedslope leaching, heap leaching and in situ leaching (Fig. ). Slope leaching: The ore is finally ground and dumped in large piles down a mountainside (Fig. ). This ore is then subjected to continuous sprinkling of water containing the desired microorganism (T. ferrooxidans).

The classic old mortar and pestle was the method used by early day miners to crush their ore specimens for testing. You can still buy these things today at most prospecting stores they are made of cast iron and last a long time and work fairly well. It just takes a lot of elbow grease and work to break up the rock.
Gold Processing Methods Gold Ore Extraction. Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration.
Extraction of iron Very unreactive metals are found directly in the ground as elements, eg. gold. Most metals are found in ores where they have reacted with other elements. Ores are rocks containing enough metal to make it economical to extract. We can extract the iron by reacting the iron oxide with a more reactive element.
