Reduction in Technogenic Burden on the Environment by Flotation Recovery of Rare Earth Elements from Diluted Industrial Solutions

Unconventional raw materials are widely used in construction sectors; for example, phosphate sludge with the addition of rare earth elements (REE) when producing brick. The second example is nanostructured composite systems REE forming covers materials. This article studies flotation recovery REE, impact chlorides on distribution coefficient, and pH recovery. study proves possibility effective from diluted industrial solutions and, consequently, significant decrease their content wastewaters, which allows improvement ecological situation plant areas. In this article, optimum conditions by given yttrium (III) lanthanum salts. processes sodium dodecyl sulphate as salts various compositions were studied. Distribution coefficients target components a function aqueous phase presence foreign anions determined. analysis dependences obtained comparison elements’ chloro hydroxo complexes stability constants was made. products authors will be manufacturing kinds building materials: carbon cement, baked brick, light materials, high-tensile steel.
