Mineralogy applied to ore dressing is a reliable guide for designing and operating an efficient concentrator. a procedure for conducting mineralogical studies in conjunction with ore dressing was, therefore, developed. the procedure includes characterizing the ore and analysing the mill products.This division includes mining for metallic minerals ores, performed through underground or open-cast extraction, seabed mining etc. also included are ore dressing and beneficiating operations, such as crushing, grinding, washing, drying, sintering, calcining or leaching ore, gravity separation or flotation operations. this division excludes mining.Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. this article was most recently revised and updated by chelsey parrott-sheffer, research editor.
072 mining of non-ferrous metal ores this division includes mining for metallic minerals ores, performed through underground or open-cast extraction, seabed mining, etc. also included are ore dressing and beneficiating operations, such as crushing, grinding, washing, drying, sintering, calcining or leaching ore, gravity separation or mining.
The beneficiation of non-ferrous metal ores, such as copper, lead, zinc, sulfur, molybdenum, etc., is mainly treated by flotation; some ferrous metals, rare metals, and some non-metallic ores, such as graphite ore, apatite, etc. are also used for flotation law selection. magnetic separation.
Mineral dressing = orebeneficiation the first process most ores undergo after they leave the mine is mineral dressing processing, also called ore preparation, milling, and ore dressing or ore beneficiation. ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate mining.

Classifiers are mainly spiral classifiers and hydrocyclones. they are widely used for classifying ore sands in the close-circuit process together with ball mill in the dressing plant, or for classifying ore sands and fine silts in gravity concentrator, classifying the particle size of ore pulp in metal beneficiation process, and for desliming and dehydration in ore dressing.
