Ib tug leaching tus neeg sawv cev yog ib yam tshuaj uas siv nyob rau hauv chemical los yog industrial processes kom yaj los yog rho tawm cov hom phiaj. Feem ntau cov kua, nws cuam tshuam nrog cov khoom siv tshwj xeeb hauv cov khoom siv khoom siv- los ntawm cov tshuaj tiv thaiv tshuaj los yog los ntawm kev tsim cov tshuaj soluble complexes - yog li cais cov hom phiaj ntawm cov khoom matrix. Hauv kev lag luam xws li metallurgy, kev tiv thaiv ib puag ncig, thiab kev ua zaub mov, leaching agents ua lub luag haujlwm tseem ceeb hauv kev sib cais thiab kev txhawb nqa.
Cov txheej txheem ntawm kev ua ntawm cov tshuaj leaching feem ntau yog nyob ntawm cov tshuaj lom neeg tawg, complexation, lossis acid- cov tshuaj tiv thaiv hauv paus. Piv txwv li, nyob rau hauv cov ntxhia leaching, tus neeg sawv cev khi nrog hlau ions tam sim no nyob rau hauv cov ntxhia pob zeb los tsim cov soluble complexes, yog li dissolving cov hlau ions tawm ntawm cov ore; Hauv kev ua zaub mov, cov tshuaj leaching tuaj yeem yaj cov khoom xyaw uas muaj nyob hauv cov nroj tsuag lossis tsiaj cov ntaub so ntswg, hloov mus rau hauv cov tshuaj. Kev xaiv thiab kev ua haujlwm ntawm cov txheej txheem no yog nyob ntawm cov khoom siv tshuaj lom neeg, concentration, thiab cov tshuaj tiv thaiv ntawm tus neeg sawv cev leaching.
Leaching agents tau siv dav hauv kev rho tawm thiab rov qab los ntawm cov tsis yog -ferrous thiab precious hlau, ua kom muaj kev sib cais zoo ntawm cov hlau xws li tooj liab, zinc, txhuas, thiab kub. Hauv kev tiv thaiv ib puag ncig, lawv tau siv los kho cov khoom pov tseg uas muaj cov hlau hnyav lossis cov av tsis huv los ntawm kev rho tawm cov hlau tsis zoo ions. Nyob rau hauv cov khoom noj thiab tshuaj industries, lawv pab txhawb lub extraction ntawm tej yam ntuj tso khoom xyaw, xws li cov nroj tsuag essences los yog alkaloids. Kev txiav txim siab xaiv thiab siv cov tshuaj leaching yog qhov tseem ceeb rau kev txhim kho kev siv cov peev txheej thiab kev tsim khoom tag nrho.
