process of obtaining pure metal from its ore

High School Earth Science/Mining and Using Minerals ...

Jan 08, 2019· But the ore's journey to becoming a usable metal is only just beginning when the ore leaves the mine. Mining produces a mixture of rocks that contain ore and other rocks that do not contain ore. So, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore.

Extraction of Metals from Concentrated Ore: Reduction of ...

After concentration of ores, we must now extract metal from in it. This step will give us metal in its pure form the native form of metal. First, we must convert the ore to a suitable form. The metals need to be in an oxide form for the reduction process to be easier. Hence the ores are converted to oxides, so it is ideal for reduction.
