Technically, flotation can be used in almost all of the mineral separation. It is especially efficient to process metal and nonmetal minerals like copper, pyrite, iron, gold, quartz, etc. Magnetic separation: Magnetic separation takes advantage of the magnetic difference of different minerals and veins and separate under magnetic effect. It is not only used in the concentration process for ...

Stone quarries come in different shapes and sizes. Some, like the gravel pits are relatively easy to reclaim. Many disused quarries, once they have been made safe, are used for leisure areas such as camp sites or motor vehicle racing tracks but the reclamation of others is more difficult. Removal of vast quantities of rock can change the very shape of our environment. Whole hillsides can be ...
