Umxholo
INkokeli (PbIsinyithi esithambileyo, esine-ductile kunye nesinokuthambeka setafile yamaxesha ekhoyo kwindalo.
Ifumaneka phi?
Uninzi lwentsimbi luyimbiwa phantsi komhlaba. Nangona kunjalo, oku akukho kwimeko yesiqhelo, kungoko kukho izinyithi ezingaphezu kwama-60 ezinokuqulatha ilothe, kodwa zintathu kuphela izinyithi ezisetyenziselwa ukukhupha ukhokelo: galena, cerussite kunye neanglesite. Okokugqibela, kubalulekile ukukhankanya ukuba eyona nto iphambili ekusebenziseni ilothe kukwenziwa kweebhetri ezinokuphinda zisebenze.
Amaminerali apho kukhokelela khona kukhokelela kakhulu kwi-galena, apho ifumaneka njenge-lead sulfide. Ke, le minerali iqulethe i-85% yelothe kwaye enye isalfure. Kukho iidiphozithi ze-galena eJamani, Mexico, United States, Spain nase Australia.
Izithando zomlilo zisetyenziselwa ukukhupha ukhokelo kwi-galena, apho i-ore ibalwa khona kwaye i-oxide iyancitshiswa de kube yinxalenye yesalfide yelothe eguqulwa ibe yi-oxide yelothe kunye ne-sulfate.
Ukuba ilothe iphantsi kwesithando ngokubala kule nkqubo, kukhutshwa ukungcola okuninzi: i-bismuth, i-arsenic, i-cadmium, ubhedu, isilivere, igolide kunye ne-zinc. Emva kokufumana ubunzima obuncibilikisiwe kwisithando somlilo esifumana igama lesithando somlilo kunye nomoya, isulfure kunye ne-steam, ezi zikwazi ukukhupha izinyithi ngaphandle kwegolide, isilivere kunye ne-bismuth. Zonke ezinye izinto ezingcolisayo ezidadayo njengenkunkuma ziyasuswa kwinkqubo.
Yintoni egqithisile:
- Ikhutshwa phi ioyile?
- Ifumaneka phi ialuminium?
- Iphuma phi i-iron?
- Ikhutshwa phi ubhedu?
- Ifumaneka phi igolide leyo?
Ukukhokelwa kwelothe
Ipayini, ikalika, i-xanthate kunye neoyile ye-alum zihlala zisetyenziswa. Ikalika okanye isinyithi sentsimbi zisetyenziswa kwinkqubo yokubhaka. Oku kuphucula inkqubo yokubhaka.
Ukurisayikilisha
Nangona kunjalo, ayizizo zonke izikhokelo ezivela kwimigodi. Kuphela yi-50% yokufumana isikhokelo esivela apho; enye iipesenti ezingama-50 ivela kurisayikilishiyitha yabaqokeleli beemoto (iibhetri).
