Eluations, also known as leaching or dissolution, is a process where soluble components are removed from a solid material by a solvent. In chemistry and industry, this technique is widely used for extracting specific substances from a mixture or a solid matrix. The effectiveness of eluations depends on several factors, including the nature of the solid material, the choice of solvent, temperature, pressure, and the contact time between the solid and the solvent.

Different types of eluations exist, categorized by the solvent used. For instance, aqueous eluations utilize water as the solvent, while organic eluations employ organic solvents like ethanol or hexane. The selection of the solvent is crucial and is based on the solubility of the target substance in the solvent. A solvent that dissolves the desired component while leaving other components undissolved is ideal for efficient separation.

In practice, eluations are employed in various fields. In mining, it is used to extract valuable metals from ore. In pharmaceutical production, it helps in isolating active compounds from natural sources or synthetic mixtures. Analytical chemistry also relies on eluations, particularly in chromatography, where different components of a sample are separated as they pass through a stationary phase, driven by a mobile phase (eluent). The term "eluent" refers to the solvent that carries the components through the system, and the "eluat" is the solution containing the extracted substances. This process is fundamental to many separation and purification techniques.
