The production of iron from its ore involves an oxidationreduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first ...

Situations when mine geologists have to sample muck piles of broken ore are very common and includes sampling of the ore stock piles, conveyor belts, tram cars and draw points of the underground stopes (Fig. ). Sampling approach is known as grab sampling and involves collecting of the rock chips of 35 cm in size.

A washing section is a "must" in all operations handling wet, sticky ore. This facilitates ore handling, crushing, and also affords a means for separation of primary slimes and increasing grinding capacity. These slimes usually contain the bulk of the soluble salts and in many cases this fraction should be treated separately or even ...

The primary consideration for the suitability of conveyor systems is the ore body geometry. New conveyor technology is allowing conveyance of material over steep grades. However, in general, conveyors are most suitable for horizontal or shallow dipping ore bodies. Typically uncrushed ore cannot be conveyed at a slope of more than 20 degrees [3].
