Iron ore mining and dressing - tec-science

Iron ore processing After the iron ore has been prepared by crushing and grinding during ore extraction, the ore is actually processed. The aim of this is to reduce the undesirable high proportion of admixtures to a desired minimum in order to increase the iron content. This is done by processes such as flotation or magnetic separation.

How can metal mining impact the environment?

As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in areas nearby. Waste piles from processing, such as tailings impoundments, leach piles, and slag piles vary in size, but can be very large.
