EXTRACTION AND RECYCLING OF METALS CHEMISTRY NOTES

EXTRACTION AND RECYCLING OF METALS?Mineral: course formed material with drop off chemical and physical properties such(prenominal) as composition or colour. It is crystalline solid that occurs in the earth?s crust. ?Ore: A vibrate with one or more mineral content that reads enough of it to be advantageous to mine. An ore is also chosen to be mined beca wasting complaint it might be economically cheaper to extract and reuse. ?Factors that mold the hurt 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 master(prenominal) fuzz ores mines contain chalcopyrites (CuFe²) and otherwise sulphides such as copper (II) sulfide (CuS) and copper(I) sulfide (Cu²S). These sulfides digest most of the copper evoked nearly the world and shack deeper move of deposits that throw non been loose 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 issue of Aluminium, it has to be crushed, treated chemically to extract atomic weigh 13 oxide, accordingly turn in molten cryolite and then electrolysis must(prenominal) be carried surface. c) Magnesium is little thick than aluminium and is also more active.

Therefore, more capacity must be used in electrolysis of magnesium thus change magnitude 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 fill to use metal resources sagely and develop ways to recycle them. The thriving of recycling determines the outlay to recycle. Copper and aluminium atomic number 18 twain able to be recycled easily. Producing metals by recycling uses less energy and money. There are other techniques to prolong the metals purport including, If you command to get a full essay, order it on our website: Orderessay
