Froth Floatation

Basics

• A Unit Process for separating Hydrophobic and Hydrophilic Components of Solid Crushed/Powdered Mixture
• Especially used in mining, where it enables the use of lower grade ores economically than conventional direct smelting of crushed ore
• It can also be applied to other use cases such as Coal Washing of Charcoal / Petcoke , and for late stages of a Material Recovery Facility / Ash Reprocessing

• Micronized Refined Carbon / Micronized Refined Coal
  • A process for Ultra Clean Coal / Ash Free Coal / Ash Free Carbon etc
  • Essentially the Material is crushed in a manner akin to conventional Pulverized Coal Combustion or Conventional Slurry Fuels , but before use it is fed into a Froth Floatation Cell
    • The Ash Content is separated and the (near) ash free carbon is either used directly as a slurry, fed into a Hydrocyclone and used in a more concentrated slurry, or Dried and used as a powder or Briquettes]] / Pellet Fuel etc
