How Metals are Mined | Cooperative Extension Service
As the machine rotates steel balls smash and grind the ore into a powder. In the case of a gold mine, the ground-up ore is mixed with water to make a slurry that is pumped to flotation cells. Flotation These are flotation cells - they are the machines that separate valuable minerals from other minerals that are in the ore.Read More
Magnetic separation - Wikipedia
The first pair of balls was weakly magnetized and served to draw off any iron ore present. The second pair were strongly magnetized and attracted the wolframite, which is weakly magnetic. These machines were capable of treating 10 tons of ore a day. It is also used in electromagnetic cranes that separate magnetic material...Read More
