Isolation Chronicles: Unveiling General Principles and Processes

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
