Amfanin zinare

Gabaɗaya za a iya raba albarkatun zinare masu jujjuyawa zuwa manyan nau'ikan guda uku:
Nau'in farko shine babban arsenic, carbon, da nau'in sulfur na zinariya.A cikin wannan nau'in, abun ciki na arsenic ya fi 3%, abun ciki na carbon shine 1-2%, kuma abun ciki na sulfur shine 5-6%.Yin amfani da tsarin hakar gwal na al'ada na cyanide na al'ada, ƙimar leaching na gwal shine gabaɗaya 20-50%, kuma ana cinye babban adadin Na2CN.Lokacin da aka wadatar da fasahar flotation, ko da yake ana iya samun mafi girman darajar zinare, abin da ke tattare da shi ya ƙunshi manyan abubuwa masu cutarwa kamar arsenic, carbon, da antimony.Zai yi tasiri a kan mataki na gaba na aikin hakar gwal.

Nau'i na biyu shine ma'adinan zinari wanda aka naɗe da zinariya a cikin ma'adinan gangue da ƙazanta masu cutarwa a cikin ƙananan ƙwayoyin cuta da ƙananan siffofi.A cikin irin wannan nau'in, abun ciki na sulfide na karfe yana da ƙananan, kimanin 1-2%, kuma an saka shi a cikin ma'adanai na gangue.Kyawawan barbashi na zinariya a cikin lu'ulu'u suna lissafin 20-30%.Ana amfani da hakar cyanide na al'ada ko hanyoyin wadatar ruwa don fitar da zinare, amma ƙimar dawo da gwal ya yi ƙasa sosai.

Nau'i na uku shine takin zinari tare da kusanci tsakanin zinare, arsenic da sulfur.Halinsa shine arsenic da sulfur sune manyan ma'adanai masu ɗaukar kaya na zinariya, kuma abun ciki na arsenic matsakaici ne.Fihirisar leaching na gwal na wannan nau'in tama ta amfani da tsarin hakar gwal guda ɗaya yana da ƙasa kaɗan.Idan zinari ya wadata ta hanyar hawan ruwa, za a iya samun mafi girman adadin farfadowa, amma yana da wuya a sayar da shi saboda ya ƙunshi arsenic da yawa.

1. Zinariya ma'adinai da rabuwa

Hanyoyin amfanar sinadarai na ma'adinan gwal sun haɗa da hanyar ruwan dumi da hanyar cyanide.Hanyar da aka haɗe tana da ɗan tsufa kuma ta dace da gwal ɗaya mai ƙaƙƙarfan hatsi.Duk da haka, yana da ɗan ƙazanta kuma a hankali an maye gurbinsa da hikima.Akwai hanyoyi guda biyu na cyanidation, yana motsa cyanidation da percolation cyanidation.

2. Chemical da kayan zaɓin zinariya

Ana amfani da hanyar sinadarai don zaɓar taman gwal, galibi hanyar yanayi.Kayan aikin da aka yi amfani da su sun haɗa da na'urar musayar foda na zinc, tankin motsa jiki, da dai sauransu. Na'urar maye gurbin foda na zinc shine na'urar da ke maye gurbin laka na zinariya daga leachate da zinc foda.

Tankin motsa leaching na'ura ce don motsa slurry.Lokacin da girman ƙwayar ma'adinai ya kasance ƙasa da raga 200 kuma ƙaddamarwar bayani yana ƙasa da 45%, ana iya kafa dakatarwa don ƙara yawan narkar da zinare a cikin tankin talla da haɓaka lokacin leaching.
