sand washing methods of fine grained iron ores

Lecture 4: Mining waste - SGU

Waste rock is the rock that is excavated to reach the ore. The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, along with the mining method used and the composition and stability of the rocks. The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be mined to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than

Iron is one of the most common elements on earth. Nearly every construction of man contains at least a little iron. It is also one of the oldest metals and was first fashioned into useful and ornamental objects at least 3,500 years ago. Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites. Most iron is found in minerals formed by the combination of iron w
