Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the proce

Benefits of Mineral Beneficiation. The benefits of mineral beneficiation or ore dressing are as follows: High volume production in lesser time. Increases the metal content of the ore. Decreases the gangue content to get the most out of the ore. It provides raw materials that support the country’s infrastructure and economy.

Concentration, dressing, or beneficiation of ores is the process of removing undesirable particles from ore. There are various steps to it. The variations in physical characteristics of the existing metal complex and that of the gangue are used to separate the needed material from the ore. Gangue is a mineral that contains undesirable elements.

The impurities left undissolved are removed by filtration. Leaching method is used for concentrating ores of aluminium, silver, gold etc. For example, bauxite (AI 2 O 3 .2H 2 O), is concentrated by this method. Crude bauxite contains ferric, oxide, titanium oxide and silica. These impurities are removed by making use of the amphoteric nature of ...
