IiNkqubo ezintathu zeGolide eziQhelekileyo zokuLeaching

KwiNkqubo yokuKhupha izinto, ngokusekelwe kumahluko kwindlela ezihamba ngayo izinto ezikhuphileyo kunye nee-reagents zokukhupha, iinkqubo ezintathu zokukhupha zinokuchongwa.

1. I-Co-current Leaching

Kwi-co-current leaching, izinto ezichithwayo kunye ne-leaching reagents zihamba ngendlela efanayo (Umfanekiso 1). Le ndlela inokuvelisa i-leachate kunye nomxholo ophezulu kakhulu wamacandelo ekujoliswe kuwo kwaye idinga ukusetyenziswa okuphantsi kwee-reagents zokuvuza. Nangona kunjalo, isantya sayo se-leaching siyacotha. Ixesha elide leaching liyafuneka ukuze kuphunyezwe izinga eliphezulu leaching.

2. Cross-current Leaching

Kwi-cross-current leaching, izinto ezifakwe kwi-leached zihlulwe ngokwahlukeneyo kunye neenxalenye ezininzi zee-reagents ezitsha zokukhupha. I-leachate efunyenwe kwi-leaching operation nganye ithunyelwa ngokufanayo kwi-procession elandelayo (Umfanekiso 2). I-Cross-current leaching ibonakalisa isantya esikhawulezayo se-leaching kunye nexesha elifutshane lokuvuza, okukhokelela kwizinga eliphezulu lokuphuma. Nangona kunjalo, umthamo we-leachate mkhulu, kunye noxinaniso oluphezulu lweerejenti ezishiyekileyo. Ngenxa yoko, ukusetyenziswa kweerejenti kukhulu, kwaye umxholo wamacandelo ekujoliswe kuwo kwi-leachate uphantsi kakhulu.

3. I-Counter-Leaching yangoku

Kwi-counter-leaching yangoku, izinto ezivuzayo kunye nee-reagents ezikhuphayo zihamba ngendlela echaseneyo. Oko kukuthi, izinto eziphelileyo emva kwemisebenzi emininzi yokuvuza idibane ne-leachate entsha, ngelixa izinto zokuqala ezikhutshiweyo ziqhagamshelana ne-leachate (Umfanekiso 3). I-Counter-leaching yangoku inokuvelisa i-leachate kunye nomxholo ophezulu wamacandelo ekujoliswe kuyo kwaye isebenzise ngokupheleleyo ii-reagents ezishiyekileyo kwi-leachate, ngaloo ndlela kuncitshiswe ukusetyenziswa kwee-ejenti ze-leaching. Nangona kunjalo, isantya sayo se-leaching sisezantsi kuneso somnqamlezo-ngoku leaching. Inani elikhulu lezigaba zokuvuza liyafuneka ukuze kufunyanwe izinga eliphezulu lokuvuza.

I-Percolation tank leaching inokusebenzisa iinkqubo zangoku, ezinqamlezayo, okanye ezichaseneyo. Imfumba yemfumba kunye ne-in-situ leaching ngokuqhelekileyo isebenzisa inkqubo ekhoyo ngoku ye-cyclic leaching. Ukuvuza okuqhubelekayo kudla ngokuthatha inkqubo yangoku yokufundisa. Ukuba kufuneka kusetyenziswe umnqamlezo-okhoyo okanye ochasene ne-current, imisebenzi yokwahlula ulwelo eqinileyo kufuneka yongezwe phakathi kwenqanaba ngalinye. Ibhetshi eqhutywa ngokuvuza okushukumayo idla ngokusetyenziswa ngokubambisana, kodwa i-cross-current or counter-leaching yangoku nayo inokusetyenziswa. Nangona kunjalo, ulwahlulo oluqinileyo-lulwelo luyafuneka emva komsebenzi ngamnye we-leaching, okwenza umsebenzi ube nzima kwaye ungasetyenziswanga kakhulu kwimveliso. Ukuvuza kwamanzi kunokufumana ngokuthe ngqo i-leachate ecacileyo, ngelixa udaka olusuka ekuvuzeni okushukumayo kufuneka lwenzeke okuqinileyo - ukwahlulwa kolwelo ukuze kufumaneke i-leachate ecacileyo okanye udaka oluludaka oluqulathe isixa esincinci samasuntswana e-ore ukuze kusetyenzwe ngokulandelayo.
