Mineral processing metallurgy Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The

Mineral Processing and Ore Dressing

Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs.

Ore Dressing Methods Metallurgist amp; Mineral Processing

Methods of Ore TreatmentThe fact that a product of high value and small bulk can be produced at a gold mine, often by relatively simple milling processes, has made it possible to operate gold mines successfully in remote and inhospitable regions where high costs of transportation, fuel, and power would make it impossible to exploit profitably basemetal ores of equal dollar value. As a result, in many instances goldmine development has been the advance guard of civilization in regions where other mineral resources

Flotation ore dressing Britannica

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.

Ore Dressing The ore will be sorted after being crushed and the useful minerals and gangue are selected, or the various useful minerals are separated from each other, which is the main part of the beneficiation. The ore dressing methods include magnetic separation, gravity separation, froth flotation, electrification, and chemical separation.

Mineral processing


Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called quot;spallingquot;. Before long, mechanical means were found to achieve this. For instance, stamp mills were used in Samarkand as early as 973. They were also in use in medieval Persia. By the 11th century, stamp mills were in widespread use throughout the medieval Islamic world, from Islamic Spain and North Africa in the west to Central Asia in the east. A later example was the Cornish stamps, consisting o
