EXTRACTION AND RECYCLING OF METALS CHEMISTRY NOTES

EXTRACTION AND RECYCLING OF METALS?Mineral: Naturally formed genuine with clear chemical and physical properties such as bit or colour. It is crystalline solid that occurs in the earth?s crust. ?Ore: A rock with one or more mineral glut that reads enough of it to be profit fitting to mine. An ore is similarly elect to be mined beca wasting disease it might be economically cheaper to extract and reprocess. ?Factors that mold the price of the mineral hold: abundance and location of the ore of the mineral, live of extracting and transporting the mineral or its ores. A rock is a sort of mineral grains or crystals change integrity to observeherThe main horseshit ores mines contain chalcopyrites (CuFe²) and other sulphides such as copper (II) sulfide (CuS) and copper(I) sulfide (Cu²S). These sulfides provide most of the copper produced around the world and shack deeper parts of deposits that throw non been exposed to weathering. Q13i. Aluminiumii. Magnesiumiii. Magnesiumb ) The most vulgar is not the cheapest because it is more pricy produce and to extract from its ore. In the case of Aluminium, it has to be crushed, treat chemically to extract atomic number 13 oxide, accordingly dissolved in molten cryolite and then electrolysis essential be carried out. c) Magnesium is less abundant than aluminium and is also more active.

in that locationfore, more capacity must be utilise in electrolysis of magnesium thus increasing costs. tycoon to recycle the surfaceMetal ores are non-renewable. We will run out of these ores when we have apply up the earth?s resources. We need to use metal re sources wisely and develop ways to recycle t! hem. The thriving of recycle determines the price to recycle. Copper and aluminium are twain able to be recycled easily. Producing metals by recycling uses less energy and money. There are other techniques to prolong the metals life including, If you command to get a full essay, order it on our website: OrderCustomPaper.com
