EXTRACTION AND RECYCLING OF METALS?Mineral: Naturally formed real(a) with clear chemical and physical properties such as report card 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 able-bodied to mine. An ore is too chosen to be mined beca wasting disease it might be economically cheaper to extract and recycle. ?Factors that mold the price 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 coagulate to devilherThe main blur 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 not been exposed 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 case of Aluminium, it has to be crushed, do by chemically to extract atomic number 13 oxide, then dissolved in molten cryolite and then electrolysis mustiness be carried out. c) Magnesium is less abundant than aluminium and is also more active.
on that pointfore, more capacity must be apply in electrolysis of magnesium thus increasing costs. tycoon to recycle the admixtureMetal ores are non-renewable. We will run out of these ores when we have employ up the earth?s resources. We need to use metal resources wisely and develop ways to recycle them. The thriving of recyc! le 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:
