The exploration stage as the initial stage of the mining process is very sensitive.Exploration operations as part of the strategy are crucial for locating and determining economical and extractable material. In the meantime, geology science , a combination of basic and technical sciences, is very important as the first step in operations.
After carrying out the exploration, and identification of the deposit and feasibility studies,the exploitation process begins, which generally refers to the set of operations that separate the ore from the deposit and transfer it to the place of minerals accumulation.
The materials extracted from mines contain significant amount of impurities and in most cases, the existence of these impurities reduces the grade of the mineral so much that it couldn't be economical for extraction. In this case processing raw materials for aquiring a product that is usefull and economical is crutial.
