Jun 21, 2018· Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process.

Manganese is widely distributed in nature, and almost all kinds of ores and silicate rocks contain manganese. In modern industry, manganese and its compounds are widely used in various economic fields, of which the iron and steel industry is one of the most important fields.

Broad exposures of this enrichment, up to 1.2 km long, assayed from 35% to 54% Fe and 17% to 45% SiO2. Ten enriched zones of major dimensions were located and six of these were roughly mapped on a scale of 1"=200 ft. Seventy-four samples were sent to Burnt Creek for analysis. Two bulk samples, each about 68 kg, were taken for ore dressing tests.

The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.
