b) Extraction of metals from their ores:-Metals are extracted from their ores in three main steps. They are :-i) Concentration of the ore (Enrichment of the ore). ii) Reduction to the metal. iii) Refining (Purification of the metal). Concentration of the ore:-is the removal of gangue (impurities) from the ore by different methods.

I. PRINCIPLES OF EXTRACTIVE METALLURGY

used for metal extraction from sulphide ores. (Slide 9-14) The word hydro- is derived from a Greek word which means water. Separation steps involved in hydrometallurgy are: leaching, purification and/or concentration, and precipitation/metal production. (Slide 15) Leaching involves preferential dissolution through water solvation,

Corrosion - PowerPoint Slides

However, during extraction of metals from their ores, free metals are become less stable and are in the higher energy state than in the ionic state. So, metals have a tendency to back to the ionic state and hence metal atoms are prone to get attacked by environment . This is the main reason for corrosion of metals.
