In the Hall's process for extraction of aluminium, Give the formula and purpose of fluorspar and cryolite. An aqueous solution of sodium chloride is not used for electrolytic reduction of sodium metal. Why? Aluminium is extracted from its chief ore bauxite. The ore is first purified and then the metal is extracted from it by electrolytic reduction.

Question: You are the head of an ore mining company that supplies the Lodge Cast Iron company with ore to use in their cast iron cookware. As with many manufacturers, consistency of inputs is key, so part of your contract is that Lodge Cast Iron takes random samples of the ore you provide and checks the density.
The world's resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.
A systematic analysis of industrial iron ore sinter product and associated sinter returns was undertaken. The samples were characterised through identification of the major macro- and micro-structural types present in these materials. Examination of the breakage surfaces of the particles indicates a strong correlation between mechanical …

The mining of iron ore, an essential raw material for Iron & Steel Industry is arguably of prime importance among all mining activities undertaken by any country. With the total resources of over 33.276 billion tonnes of haematite (Fe 2 O 3) and magnetite (Fe 3 O 4
Iron ore mining methods vary by the type of ore being mined. Currently, there are four main types of iron ore deposits, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite, and piso-litic ironstone deposits. For taconite iron ores, mining iron ore begins at ground level.
Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.
These countries account for around 85 % of the total global iron ore mining volume. Ore deposits are natural accumulations of ores that can be mined economically! The iron ore extracted in the deposits, mostly by blasting, is initially very coarse and unwieldy, which gives this untreated rock the name coarse ore.
The processing methods largely depend on the characteristics of the ore itself and the nature of association of gangue with the ore. This chapter will try to give an overview of important aspects involved in iron ore processing including iron ore mining, iron ore handling, and iron ore beneficiation and agglomeration.
