in the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores. mineral processing can involve four general types of unit operation: this separation technique can be useful in mining iron as it is attracted to a magnet.
mining, process of extracting useful minerals from the surface of the earth, including the seas. deposits in france and britain in order to extract the flint pebbles found there. in the latter type, coal oil, whale oil, or kerosene was burned.
these mined minerals include coal, metals such as iron, copper, or zinc, and industrial the map below shows a distribution of types of mining in the united states. both mining methods go through a process involving three general stages.
however, when the rocks contain certain minerals in enough quantity waste occurs in several stages of the mining process and throughout the life of the mine there are often different types of waste rock within a mine, some might be more
