Zorluk: ZorIndustrial Applications of Separation Methods

In chemical manufacturing and hydrometallurgy, specific separation methods are chosen according to the physicochemical properties of the mixtures involved. Match each industrial separation technique listed on the left with its corresponding operational principle and application on the right.

  • Froth flotationSeparation of hydrophobic mineral ore particles (such as ZnSZnS) from hydrophilic gangue based on differences in surface wettability
  • Vacuum distillationSeparation of heavy petroleum residues at reduced pressure to lower boiling points and prevent thermal decomposition (cracking)
  • Solvent extractionSelective recovery of target metal ions (Cu2+Cu^{2+}) from dilute leach liquor into an immiscible organic phase containing extractants
  • Precipitative crystallizationSeparation of solid NaHCO3NaHCO_3 from ammonium chloride solution in the Solvay process by exploiting solubility limits at controlled temperatures

Cevap

Froth flotation matches the separation of hydrophobic mineral ores based on surface wettability. Vacuum distillation matches the separation of heavy petroleum residues at reduced pressure to prevent thermal cracking. Solvent extraction matches the selective recovery of metal ions into an immiscible organic phase. Precipitative crystallization matches the separation of solid NaHCO3NaHCO_3 in the Solvay process by exploiting solubility limits.
Each technique is matched to its primary industrial application based on physical/chemical properties: Froth flotation relies on surface wettability differences; Vacuum distillation uses reduced pressure to lower boiling points of thermal-sensitive heavy oil; Solvent extraction uses differential solubility in immiscible liquid phases for hydrometallurgical metal purification; Precipitative crystallization relies on solubility thresholds to precipitate NaHCO3NaHCO_3 in the Solvay process.

Adım Adım Çözüm

1
Analyze Froth Flotation
Froth flotation utilizes surfactants and air bubbles to selectively attach to hydrophobic ore particles (e.g., ZnSZnS), floating them away from hydrophilic waste rock (gangue).
Difference in surface wettability is the core physical property utilized in flotation.
2
Analyze Vacuum Distillation
Heavy petroleum crude fractions decompose at high temperatures required for boiling at atmospheric pressure; reducing pressure lowers boiling points.
Lowering ambient pressure allows distillation below thermal decomposition (cracking) thresholds.
3
Analyze Solvent Extraction
In hydrometallurgy, metal ions in dilute aqueous solution are extracted into an immiscible organic liquid containing specific chelating ligands.
Different solubilities and partition coefficients drive transfer between immiscible liquid phases.
4
Analyze Precipitative Crystallization
In the Solvay process, passing carbon(IV) oxide into ammoniacal brine forms NaHCO3NaHCO_3, which precipitates due to low solubility relative to NH4ClNH_4Cl.
Temperature-controlled crystallization isolates solid products from soluble reaction side-products.
