  • vees lahustuvate soolade väljauhtumine, kitsamas tähenduses karbonaatide lagunemine ja uhtumine mullast
  • process of removal of soluble and colloidal substances by water percolating downwards through the soil layers, by which the upper layer of leached soil becomes increasingly acidic and deficient in plant nutrients
  • proceso de eliminación de sustancias solubles y coloidales del suelo por acción de la percolación del agua, durante el cual la capa superior del suelo se acidifica y pierde los nutrientes de las plantas
  • 1. evacuation des sels de la couche supérieure du sol par de l'eau relativement peu chargée en sels - 2. evacuation par effet de chasse des polluants contenus dans des eaux usées emmagasinées
  • процесс удаления растворяемых и коллоидальных веществ при просачивании воды через слой почвы, при этом верхний слой выщелоченной почвы становится более кислым с дефицитом питательных веществ для растений

  • lahustuvate metalliühendite eraldamine tahkest materjalist, sh maakidest, lahustite (nt tsüaniid, väävelhape jms) abil; järgneb metalli väljasadestamine või absorbeerimine lahusest
    Good to know
    • Kasutatakse metallide tootmiseks hüdrometallurgias (vt hüdrometallurgia).
  • the extraction of a soluble metallic compound from a solid material, in particular from ore, by dissolving in a solvent e.g. cyanide, sulphuric acid etc; the metal is subsequently precipitated or absorbed from the solution
    Good to know
    • Leaching is used for hydrometallurgical production of metals. (see: hydrometallurgy)
  • выделение составляющих частей твёрдого материала при помощи растворов (напр. цианид, серная кислота, и т. д.), в т. ч. из руд; основано на лучшей растворимости выделяемого вещества по сравнению с другими составными частями; за растворением следует осаждение или абсорбирование металла из раствора
    Good to know
    • Выщелачивание применяется для получения металлов в гидрометаллургии. (см. гидрометаллургия)
