Iintsimbi zegolide zenziwe njani: ukusuka kwizinto eziluhlaza ukuya kwimveliso egqityiweyo

Igolide ibe luphawu lobutyebi kunye nokuchuma kangangeenkulungwane, kwaye inkqubo yokwenza ibha yegolide luhambo olunomdla ukusuka kwizinto eziluhlaza ukuya kwimveliso egqityiweyo. Umtsalane wemivalo yegolide ekhazimlayo iye yathimba izizukulwana, kwaye ukuqonda inkqubo enzima yokuyenza yongeza kwi-mystique yale ntsimbi ixabisekileyo. Yonke le nkqubo iya kufuna umatshini wesinyithi wegranulating umatshini wokugalela ibha yegolide , umatshini wokubetha uphawu.

Uhambo lokudala imivalo yegolide emenyezelayo luqala ngokukhupha intsimbi ekrwada ekrwada emhlabeni. Igolide idla ngokuvela ngokwemvelo ematyeni kunye nentlenga ngendlela yeenuggets okanye amasuntswana. Emva kokuba intsimbi ikhutshiwe, iqhuba uthotho lweenkqubo ezahlula igolide kwizinto eziyingqongileyo. Oku kubandakanya ukutyumza nokusila intsimbi ekrwada ibe ngumgubo ocolekileyo kwaye emva koko kwenziwe iinkqubo zemichiza ezifana ne-cyanidation okanye i-flotation ukukhupha igolide.

Emva kokuba igolide ikhutshiwe kwintsimbi ekrwada, ibakho ikwimo yegolide, equlethe ipesenti ephezulu yegolide esulungekileyo. Inyathelo elilandelayo kule nkqubo kukucokisa ukugxila kwegolide ibe yigolide esulungekileyo. Oku ngokuqhelekileyo kwenziwa ngenkqubo ebizwa ngokuba yi-smelting, apho igolide egxininisekileyo ifudunyezwa kumaqondo obushushu aphezulu kwiziko. Njengoko iqondo lobushushu lisanda, ubumdaka obukwigolide buyahlukana negolide esulungekileyo, busenza igolide etyhidiweyo.

Yakuba igolide isulungekisiwe ibe yimo etyhidiweyo, ilungele ukwenziwa imivalo yegolide. Igolide etyhidiweyo igalelwa kwi-mold, ngokuqhelekileyo eyenziwe ngegraphite okanye intsimbi, ukuze yenze imilo yegolide. Ezi zibumba ziyilelwe ukuvelisa izitena zegolide ezinobunzima obuthile kunye nobukhulu, ukuqinisekisa ukuba ibha nganye ihlangabezana nokucoceka okufunekayo kunye nemigangatho yomgangatho.

Emva kokuba igolide etyhidiweyo igalelwe kwi-mold, ivumelekile ukuba iphole kwaye iqiniswe, yenze imivalo yegolide eqaqambileyo efana nobutyebi kunye nokunethezeka. Emva kokuba imivalo yegolide iqinile, iyasuswa kwi-molds kwaye ihlolwe ngokulandelelana ukuqinisekisa ukuba ihlangabezana nokucoceka okufunekayo kunye nemigangatho yomgangatho. Oku kuquka ukuvavanya i-nugget yegolide nganye yobunzima, ubungakanani kunye nokucoceka ukuqinisekisa ukuba iyahlangabezana neenkcukacha zemarike.

Inyathelo lokugqibela kwinkqubo yokudala ibha yegolide ekhazimlayo kukugximfiza ibha eneempawu ezifanelekileyo kunye nenombolo yolandelelwano. Oku kwenzelwa ukuqinisekisa ubunyani kunye nokusulungeka kwegolide le bullion kunye nokubonelela ngendlela yokulandela umkhondo wegolide kulo lonke uhambo lwayo lokuya kwintengiso. Iimpawu ngokuqhelekileyo ziquka ubunzima, ubunyulu, uphawu lwendawo yokucoca okanye i-mint evelise ibha yegolide, kunye nenombolo yesiriyali ekhethekileyo yokuchongwa.

Inkqubo yokudala imivalo yegolide emenyezelayo yinkqubo ecokisekileyo nechanekileyo eguqula intsimbi ekrwada ekrwada ibe luphawu lobutyebi kunye nempumelelo. Ukusuka ekutsalweni kwezinto ezikrwada ukuya ekusulungekisweni nasekuphosweni kweentsimbi zegolide, inyathelo ngalinye kwinkqubo lifuna ingqalelo ecokisekileyo kwiinkcukacha kunye nokubambelela kwimigangatho engqongqo yobulunga.

Lilonke, inkqubo yokudala imivalo yegolide emenyezelayo ibubungqina bokuba igolide inomtsalane njengentsimbi exabisekileyo. Ukususela kwintsimbi ekrwada ekrwada ekhutshwe emhlabeni ukuya kwimveliso eqaqambileyo egqityiweyo, inkqubo yokwenza izitena zegolide ngumxube obangel’ umdla wenzululwazi, ubugcisa kunye nobugcisa. Ukuqonda inkqubo entsonkothileyo yokwenza imivalo yegolide kukhulisa ukuqonda ngexabiso kunye nokubaluleka kolu phawu olungaphelelwa lixesha lobutyebi kunye nokuchuma.
