A large diversity of mechanical means are used to separate magnetic materials. [2] During magnetic separation, magnets are situated inside two separator drums which bear liquids. Due to the magnets, magnetic particles are being drifted by the movement of the drums. This can create a magnetic concentrate (e.g. an ore concentrate). [2]
A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.
Flake hammerscale forms due to the rapid oxidation of hot iron in air. A heated piece of iron will develop an external layer of iron oxide which then may separate from the original piece due to a hammer strike or differential thermal contraction. [6] Flake hammerscale is produced in large quantities during multiple stages of the smithing ...
Decanting a liquid from a solid. Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. [1] The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving denser liquid or the solid behind.
A mixture can separate into more than two liquid phases and the concept of phase separation extends to solids, i.e., solids can form solid solutions or crystallize into distinct crystal phases. Metal pairs that are mutually soluble can form alloys , whereas metal pairs that are mutually insoluble cannot.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
The broken pieces appeared to fit together, with some of the runic script from one stone continuing onto another, and the scientists realized the fragments were all once part of a single stone.
In chemistry, fractional crystallization is a stage-wise separation technique that relies on the liquid–solid phase change. This technique fractionates via differences in crystallization temperature and enables the purification of multi-component mixtures, as long as none of the constituents can act as solvents to the others. Due to the high ...
