Overview

Metallurgy is the science and technology of extracting metals from their ores and preparing them for use. This chapter explores how metals occur in nature, the various processes involved in extracting pure metals from ores, and methods to prevent metal corrosion. Understanding metallurgy helps us ap

Key Concepts

Minerals are naturally occurring compounds

Minerals are naturally occurring compounds or elements of metals found in earth's crust. Ores are minerals from which metals can be extracted economic

Metals are arranged in decreasing order

Metals are arranged in decreasing order of reactivity: K, Na, Ca, Mg, Al (high reactivity) > Zn, Fe, Pb, Cu (moderate reactivity) > Hg, Ag, Pt, Au (lo

The process of removing impurities (gangue)

The process of removing impurities (gangue) from ores using physical methods. Methods include: hand picking (based on color/size differences), washing

Different methods based on metal reactivity

Different methods based on metal reactivity: Electrolytic reduction (for highly reactive metals like Na, Mg, Al), Chemical reduction with carbon or CO

Methods to obtain pure metals from

Methods to obtain pure metals from crude metals: Distillation (for low boiling metals like Zn, Hg), Poling (stirring molten metal with green wood pole
