The Guangling hematite ore sample consisted of 58.83% Fe 2 O 3, 19.53% SiO 2, 6.75% Al 2 O 3, 0.21% FeO, 2.46% CaO, 1.38% MgO, 0.11% Na 2 O, and 3.65% K 2 O. Harmful elements, such as phosphorus and sulfur, were present in only low quantities. This hematite ore contained a small amount of magnetite; hematite is the precious form of iron minerals.
Dry Ashing. Dry Ashing is usually performed by placing the sample in an open inert vessel and destroying the coustible (organic) portion of the sample by thermal decomposition using a muffle furnace. Typical ashing temperatures are 450 to 550 °C. Magnesium nitrate is commonly used as an ashing aid. Charring the sample prior to muffling is
The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated.
Fig 1 A typical open pit iron ore mine. On the basis of mining methods, iron ore mining can be broadly divided into two egories namely manual mining and mechanized mining. Large iron ore mines are mechanized mines while manual mining methods are employed in the small mines. Manual mining method is normally limited to float ores.
