Quoted PriceOre Grade Reconciliation Techniques A Review
The essence of ore grade reconciliation is to identify, analyse and manage variance between planned and actual results in a way that highlights opportunities. A consistent record of poor reconciliation is an indication that this variance has not been adequately managed. This would inevitably result in significant economic impact on mining companies.

Essay Classification of Iron Ore According to usage, function ability and composition, iron ores are principally of four major types A. Magnetite (Fe 3 O 4) It is the richest among all iron ores with little impurities. The iron content varies between 70 to 72.5%. It contains magnetic properties, therefore it is suitable for electrical industries.

Types of iron ore. The major rock types mined for the production of metallic iron are massive hematite, pisolitic goethite/limonite, which provide a 'high grade' ore, and banded metasedimentary ironstone, magnetite rich metasomatite, to a much lesser degree, rocks rich in siderite, rocks rich in chamosite which provide a 'low grade' ore.

Different percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use. In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required.

Hematite and magnetite, the two predominant iron ores, require different processing routes. High grade hematite direct shipping ores (DSOs) generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products. Low grade hematite ores require additional beneficiation to achieve the desired iron

OverviewExtractionSourcesMine tailingsProduction and consumptionAbundance by countrySmeltingSee alsoLower grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high quality fine ore powders, are known as fines.
Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a high grade concentrate with very low levels of impurities.

Mineral Classification. Cut off grades are used to determine the point at which material becomes economically valuable. Therefore, they are necessary to define the amount of ore in a deposit. The classification of ore depends entirely on cut off grade. Increasing the cut off grade places a stricter requirement on what can be considered ore.
