The metal ore does not adsorb water but does adsorb the pine oil. The oil-coated ore floats to the top of the mixture, where it can be skimmed off. Reduction. Metals always occur in their oxidized state in ores, often as the oxide or sulfide of the metal. In order to convert an ore to its elemental state, therefore, it must be reduced. Reduction is a chemical reaction that is the opposite of ...

General principles of extraction of metals

these metals can be obtained by the thermal decomposition of their oxide ores. 4. The oxide of a metal which is above another metal in the Ellingham diagram can be reduced by the latter. Thus, Mg can reduce Cr 2 O 3; Al can reduce Fe 2 O 3. For such a reduction, the free-energy change [metal(m1) oxide + metal(m2) → metal(m1) + metal(m2)oxide] is negative. For example, in the reduction Uses ...

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Copper Mining and Production Processes Explained

An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding. The ore is crushed, then ground into powder. Concentrating. The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting . This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and ...
