Methods of enrichment of ore Now we shall discuss the different processes which are used for enrichment of different types of ores 1 Hydraulic Washing This method is used for the enrichment of those ores which are heavier than gangue particles present in them In this method a stream of water is passed through crushed and finely powered ore

Hii The method used to extract metals from the ore in which they are found depends on their reactivity For example reactive metals such as aluminium are extracted by electrolysis while a less-reactive metal such as iron may be extracted by redu

These techniques are used in various combinations for the beneficiation of iron ores Iron ore is normally beneficiated utilizing the principles applied in separation of the materials by the gravity floatation and magnetic methods Enrichment of ores utilizing the gravity concentration method is one of the oldest and most economic techniques

Gravity concentration methods separate minerals of different specific gravity They are used to treat a great variaty of materials [ranging from Au ( sp gr 19 3 ) to coal ( sp gr 1 3 ) ] Gravity concentration methods remained however the main concentrating methods for iron tungsten tin ores and coal

on the recommendation of the Methods of Chemical Analysis of Ores Minerals and Refractories Sectional Committee (MTD 29) and approval of the Metallurgical Engineering Division Council This method is applicable to a concentration range of 0 003 to 1 0 % (m/m) of copper in natural iron ores and iron ore con- different time or by a

Principles of gravity concentration Gravity concentration methods separate minerals of different specific gravity by their relative move- ment in response to gravity and one or more other forces the latter often being the resistance to motion offered by a viscous fluid such as water or air

In addition to processing copper ores new and old copper scrap or copper alloys can be melted re-purified and recycled into new components It is estimated that such recycling supplies 50% of copper used in the copper industry (Scott 2011)
