Where to find the "iron ore" and how they do in the metal?

Obviously, it melts. What is the process in question? Where is exactly iron ore. .. and how to remove it? Moreover, since metals are natural elements, how they form, in the first place? Complementary: Where do we get aluminum (bauxite) and how can we draw? : Where do we find all this and how do they differ?: aluminum, steel, chrome, silver, brass. How do they form? Please only answer if you know what your talking about (not guess). Thank you.

An ore is a mineral that in its economic development to extract the metal from it. Minerals are found in rocky soil. A mineral is a metal that reacts with metals to form a compound. Usually reacts with oxygen or sulfur. There are various processes to extract metal from ore each. But generally follows the process of grinding the ore, it purifies by removing impurities, and then to reduce minerals (metals startup) and make —————– — pure aluminum metal is the metal most abundant in the earth's crust, aluminum ore from receiving is called bauxite (Al2O3. 2H2O) We extract aluminum from bauxite using the following method: 1. first impure bauxite milled down to a powder 2. then dissolved in a solution of sodium hydroxide (NaOH) 3.The aluminum oxide and iron oxide impurities dissolve therein. All other impurities are dissolved and filtered. 4. Then the solution is heated. Crystallized aluminum oxide to aluminum hydroxide (Al (OH) 3), while iron oxide 5. near the glass filter and have solid aluminum hydroxide. Next heat the aluminum hydroxide and obtain aluminum oxide (Al2O3) 6. Next we make the aluminum oxide in the pure aluminum metal. Aluminum oxide using electrolysis, is added to an iron tank and mixed with cryolite (Na2AlF6) and fluorspar (CaF2) this reduces the melting point of it and also helps conduct electricity Next we flow of electricity through it. The divisions of aluminum oxide and aluminum + oxygen ions. The head of aluminum ions negative twards the end (cathode). The head of atoms oxygen twards the positive end (anode). The ions then get the electrons from the terminal and made of metal and aluminum, aluminum oxygen The gas we have is 99% pure, we can do this again and again to make it more pure —————————– —- – steel, chrome, and brass are alloys. They are a mixture of different metals. aluminum and silver are the pure metals. Usually they make alloys that have properties of both metals in 1. I think that steel is iron with some carbon added for strength and corrosion resistance
