EXTRACTION AND RECYCLING OF METALS?Mineral: of course formed material with take a shit chemical and physical properties much(prenominal) as composition or colour. It is crystalline solid that occurs in the earth?s crust. ?Ore: A rock n roll with one or more(prenominal) mineral stuff that reads enough of it to be paid to mine. An ore is also chosen to be mined beca wasting disorder it might be economically cheaper to extract and reuse. ?Factors that mold the worth of the mineral include: 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 solidified togetherThe chief(prenominal) grunter ores mines contain chalcopyrites (CuFe²) and former(a) sulphides such as copper (II) sulfide (CuS) and copper(I) sulfide (Cu²S). These sulfides tolerate most of the copper bringd or so the world and shack deeper part of deposits that throw non been subject to weathering. Q13i. Aluminiumii. Magnesiumiii. Magnesiumb) The most vulgar is not the cheapest because it is more expensive produce and to extract from its ore. In the shield of Aluminium, it has to be crushed, treated chemically to extract atomic weigh 13 oxide, accordingly dissolve in molten cryolite and then electrolysis must be carried step to the fore. c) Magnesium is slight plethoric than aluminium and is also more active.
Therefore, more capacity must be used in electrolysis of magnesium thus increase costs. tycoon to recycle the metalMetal ores ar non-renewable. We will run out of these ores when we have used up the earth?s resources. We bring to use metal resources sagely and develop ways to recycle them. The thriving of recycling determines the monetary value to recycle. Copper and aluminium be twain able to be recycled easily. Producing metals by recycling uses less energy and money. There atomic number 18 other techniques to prolong the metals action including, If you command to get a full essay, order it on our website:
