Leaving behind the supernatant, and often occurring after the contamination of a supersaturated solution, for 10 points, identify this process, in which the product of a chemical reaction carried out in solution forms a solid deposit.
Leisegang rings form as a product of this process, and the Cohn process uses it to recover albumin. It is exploited in the isolation of francium via cesium salts, though an associated phenomenon can plague gravimetric analysis. It can be induced by anti-solvents, and oxalic acid typically causes it in the presence of metals, leading to kidney stones.
