Thaum siv cov khoom no, cov kuab tshuaj kub yuav tsum tau yaj hauv dej raws li qhov piv txwv los npaj cov tshuaj leaching, uas yog tom qab ntawd coj mus rau hauv kev sib cuag nrog cov ore. Thaum lub sijhawm ua haujlwm, nws yog ib qho tseem ceeb los tswj cov tshuaj pH thiab lub sijhawm tshuaj tiv thaiv kom ua kom cov nyhuv leaching. Thaum lub sijhawm khaws cia, ib puag ncig yuav tsum tau khaws cia kom qhuav thiab noo noo - pov thawj los tiv thaiv cov hmoov clumping, uas yuav cuam tshuam rau kev ua kom tiav. Raws li cov khoom lag luam tsis yog - tshuaj lom neeg, tsis tas yuav muaj kev pom zoo tshwj xeeb rau kev thauj mus los thiab khaws cia, tab sis nws yuav tsum tau khaws cia kom deb ntawm cov khoom muaj zog oxidizers lossis cov kua qaub kom tiv thaiv kev sib tsoo.
Cov kuab tshuaj kub feem ntau ua haujlwm kub mining thiab smelting tuam txhab, npog tag nrho cov txheej txheem los ntawm ore crushing mus rau refining thiab purification. Nws cov ntawv thov suav nrog qhib- qhov mines, mines hauv av, thiab tailings kev txhim kho theem nrab, thiab nws yog qhov tshwj xeeb tshaj yog tsim rau kev ua haujlwm qis - qib ores lossis complex ore lub cev. Los ntawm kev txhim kho tus nqi leaching, qhov reagent no tsis ncaj qha txo cov nqi tsim khoom ntawm ib chav tsev kub, uas yog qhov tseem ceeb rau kev txhawb nqa kev hloov pauv ntsuab thiab kev siv peev txheej ntawm kev lag luam kub.
