The common tungsten extraction methods are surface (or open pit) mining and sub-surface (or underground) mining, or a coination of both. Modern tungsten processing methods dissolve scheelite and wolframite concentrates by an alkaline pressure digestion, and
explain the method for extraction of highly reactive metals with example - Science - Metals and Non-metals Most of the ores are in forms of oxides and sulfide they are generally extracted by reduction with carbon.But the metals which are more reactive than carbon cannot be obtained by this process. Bauxite must be purified prior to
2006-6-27 · Minerals are solid elements or compounds found naturally in the Earth''s crust. Those minerals that contain sufficient metal to be of practical and economic use are called ores. Metals are usually extracted from ores using a coination of heating and reduction with carbon in the form of charcoal or coke.

Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.
Copper is usually purified from an ore where it is coined with other elements. Silicon is purified from SiO2 (natural quartz). Coltan is an ore containing oxides of metals such as tantalum and niobium (aka coluium) that must be purifed to get these desirable elements in a concentrated form suitable for the manufacture of electronic components.
