Extraction of metals. The process of extracting metal ores buried deep underground is called mining. The metal ores are found in the earth's crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground. The ores are very different from the finished metals that we see in buildings and bridges.

This is smelted in a small furnace to oxidize virtually all metals present except silver, gold, and platinum-group metals. The metal recovered, called doré, generally contains 0.5 to 5 percent gold, 0.1 to 1 percent platinum metals, and the balance silver. This metal is cast to form anodes and electrolyzed in a solution of silver-copper nitrate.

In addition to physical similarities and shared interests, the mining, metals and recycling sectors also share a common mentality: in recycling, a product consists of different materials that need to be separated out, just as in mining and refining, an ore contains different minerals and metals that must be separated.
Lithium brine ponds: concentrating and precipitating impurities from geological lithium brines via evaporation ponds.A highly concentrated lithium solution is subsequently refined and converted into lithium carbonate or hydroxide. These low-cost operations are ideal for the convergence of rich lithium brines and arid climates, such as South America's 'lithium …
Refining is the process of purifying an impure metal. It's easiest to think of precious metals refining as a method of recycling. The refining process takes products or byproducts containing precious metals (such as jewelry or dental scrap) and isolates the metals back into more purified states for recirculation.

Any metal in the impure anode which is below copper in the electrochemical series (reactivity series) does not go into solution as ions. It stays as a metal and falls to the bottom of the cell as an "anode sludge" together with any unreactive material left over from the ore. The anode sludge will contain valuable metals such as silver and gold.
