There are many important topics that we have to study in this chapter such as
- Minerals and Ores
- Gangue and Flux
- Types of Flux : Acidic and Basic Flux
- Stag = Gangue + Flux = Stag
- Refractory Materials
- Metallurgy
- Steps of metallurgy : (i) Concentration of the ores, (ii) Extraction of metal from the concentrated ore & (iii) Purification of metal
- Some process are involved in the concentration of the ore which are following –
(i)Gravity Seperation method
(ii) Froath floatation method
(iii) Magnetic seperation method
(iv) Chemical seperation method
- Extraction of metal from the concentrated ores – (i) Conversion of concentration ores to its oxide from and (ii) Conversion of metallic oxide to the metallic form
- Soft Reduction Method
- Purification of metal – (i) Liquation, (ii) Distillation, (iii) Oxidation, (iv) Poling and (v) Electrorefining
- Extraction of Zinc
- Extraction of Aluminium
- Extraction of Iron
- Phases of Colloidal Solution – Dispersed phases and Dispersion medium
- Types of colloids : Lyophilic & Lyophobic colloids
- Types of colloids on the basis of size of dispersed phase : Multimolecular, Macromd cular & associated colloids.
- Properties of Colloidal solution
- Brownian Movement & its causes
- Tyndall Effect & important condition for Tyndall Effect
- Electrophoresis
