Linger Environmental Effect of Mining Erosion. According to Massachusetts Institute of Technology (MIT) the effects of mining erosion can linger long after the mining has ended. Large swathes of land are impacted, beyond the immediate surroundings of the mine. Metallic dust from copper and nickel mines often persist for many decades and can even reach areas 2-3 miles away from the actual mines ...Environmental Damages of Mining. Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount ...

The apatite Mineral Group Apatite is named for the Greek word apate, which means "deceit", since Apatite is similar in appearance to many other minerals. Apatite describes a group of similar isomorphous hexagonal phosphate minerals. The primary Apatite group includes Fluorapatite, Chlorapatite, and Hydroxylapatite.Tests with tailings sand (waste material which is a by-product of mining) from the two mines and the respective processing plants will be carried out in campaigns. Right now, a production campaign is underway in Malmberget. The process has multiple steps, flotation is the key principle applied to separate the apatite from the non-valuable tailings.
