It all depends on the principles of metallurgy we use to check the inorganic chemical properties of the constituents of an ore. This is how an extraction process is designed. Every constituent is analyzed and then the most suitable process of separating it from the rest is chosen. The basic extraction of metals from ores has the following steps. 1.
Rocks with large concentrations of minerals, are called ores. Mining depends on finding good quality ore, preferably within a small area. The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of getting the mineral you want out of the rock can start.
