What Methods Are Used To Seperate Ore From Other Rock

Separating Iron and gold from rock. by Elsa Huber

There are many ways to extract iron ore from rock. Iron is magnetic so you could use a method that involves magnets, and it is also heavier than a lot of substances, so you could use a shaker and see which pieces weigh more. However, the way that we thought to separate iron ore

What Are the Different Uses of Iron Ore? (with pictures

1/13 · Iron-rich ores have a number of other uses, some of which are literally quite colorful; they are used in cosmetics, for example, and in the production of some paints, inks, and dyes. Manufacturers distinguish between high and low grade ores that contain different impurities mixed with the iron and determine the end uses of iron ore.
