Which of the following is NOT one of the six methods of separation?

Centrifugation, evaporation, and filtration are widely recognized methods of separation used in various chemistry applications.

Centrifugation employs the principle of density differences, where a mixture is spun rapidly to separate components based on their mass. Heavier particles move outward and settle at the bottom, while lighter ones remain suspended.

Evaporation is utilized to separate a solute from a solvent by converting the liquid into vapor, leaving the solid residue behind. This method is commonly applied in processes such as concentration of solutions.

Filtration works by separating solid particles from a liquid or gas using a barrier that allows only certain sized particles to pass through, effectively isolating solids from fluids.

Amalgamation, however, is not considered one of the standard methods for separating materials in a laboratory or industrial context. It primarily refers to a process in metallurgy, specifically dealing with the extraction of metals using mercury. This makes it distinct from the typical methods used for separating mixtures in chemistry, which are geared towards physical separation techniques.
