Beginners Guide to Stope Mining
Before explosives in the form of gunpowder were introduced to mining in the 1600s, miners carved rudimentary small-scale stopes by hand.. Gunpowder was replaced by dynamite in the mid-1900s, and power tools and machinery followed shortly after. As technology progressed, so did the mine design process.
Magnetic Separation
A belt separator is similar except that the magnet is located between pulleys around which a continuous belt travels. Magnetic separation has some limitations. It cannot separate iron and steel from nickel and magnetic stainless steels. Also, composite parts containing iron will be collected which could contaminate the melt.
