Mined right out of the ground raw ore is mix of ore proper and loose earth called gangue The ore proper can usually be separated by crushing the raw ore and simply washing away the lighter soil Breaking down the ore proper is more difficult however as it is a chemical compound of carbonates hydrates oxides silicates sulfides and various impurities.
sodium cyanide which is used on most gold mines to help process the ore Xanthates used as a flotation chemical solvents and compressed gases may also be found Hazardous chemicals such as sulphur dioxide hydrogen sulphide carbon monoxide and oxides of nitrogen may be generated during the processing of mineral ores.
Mary McMahon Iron is often used to make permanent magnets One of the most important uses of iron ore is steel production accounting for the bulk of iron ore processed annually Iron rich ores have a number of other uses some of which are literally quite colorful they are used in cosmetics for example and in the production of some paints inks and dyes.

Mary McMahon Strip mining is done layers where the mining operations go slighter deeper with each pass Strip mining is a type of surface mining which involves the removal of a thin layer of material known as an overburden to access buried deposits of useful minerals.This type of mining is only effective in areas where mineral deposits are very close to the surface making
Though there are nineteen kinds of iron ore known to the mineralogist it has been calculated that nine tenths of the iron produced is derived from the clayband and blackband ironstones the relative value of which is thus stated in a paper read before the Scottish Society of Arts by Mr Ralph Moore Government inspector of Mines Clay ironstones contain from thirty to fifty
