Mar 28, 2015 · Processes for Beneficiation of Iron Ores Iron is an abundant element in the earth''s crust averaging from 2 % to 3 % in sedimentary rocks to 8.5 % in basalt and gabbro. Because iron is present in many areas, it is of relatively low value and thus a deposit must have a high percentage of metal to be considered ore grade.
Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large
Major problem faced with the Indian iron ore is that though they are very rich in iron content they also have a high content of gangue material like silica and aluminium which obstruct the iron and steel production as the performance of the blast furnace lowers. Iron ore sample found is a part of banded iron ore formation.

Mar 15, 2015 · The energy consumption of ore comminution, especially of the grinding processes, is about to rise in the next years, due to wellknown reasons. Deteriorating ore grades force the mining companies to mine and process more raw material to ensure that the refining industry is adequately supplied with ore concentrates.
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
