Ukukhupha iGolide kwiOre yeGolide ene-Oxidized

Ngokwendalo, igolide ayisebenzi ngeoksijini ukwenza iioksidi njengentsimbi okanye ubhedu. Enoba ungcwatywe emangcwabeni, esantini, okanye uphumle elwandle kangangamawaka eminyaka, amasuntswana egolide, iinkozo, nemivalo isaqhubeka iqaqamba ngokuqaqambileyo.

Ngoko ke, ukuba igolide ayivuthisi, yintoni kanye kanye i-ore yegolide evuthisisiweyo?

Ukuqonda iintsimbi zeGolide eziOxidized

Intsimbi ekrwada yegolide ene-oxid ibhekisa kwigolide-intsimbi ekrwada eyenziwe ngeenkqubo zendalo ze-oxidation, endaweni yeeoksidi zegolide.

Ezo ore zikholisa ukuba negolide kunye neeoksidi zesinyithi njengentsimbi, ubhedu, kunye nemanganese. Iiminerali eziphambili yi-limonite kunye ne-pyrite, ene-sulfide encinci okanye engenazo, kodwa ibandakanya iiminerali ezizinzileyo ezinje ngegolide-ethwele i-iron hydroxides okanye i-hydrated iron oxides, kunye ne-quartz ethile.

Umphezulu wemozulu uguqula iiminerali eziphambili zesulfide zibe ziioksidi kunye neehydroxides, kunye negolide enokuthi ifakwe kwihematite, goethite, okanye imonite.

Ore yegolide ene-oxid idla ngokubonakala tyheli ukuya kumdaka kwaye inokwakheka okuxekethileyo. Yimathiriyeli ekrwada ebalulekileyo kwimveliso yegolide.

Indlela yokutsalwa kweGolide kwiOre yeGolide ene-Oxidized?

Kwigolide ekrwada ene-oxidized, uninzi lwegolide luqulethwe kwiiminerali eziphambili ze-ganggue kunye nokuqhekeka kwee-oxide zetsimbi. Ubungakanani begolide buhluka kakhulu, kwaye ukubunjwa kwamaminerali kulula.

Phambi kokuba uqalise iinkqubo zokutyumza kunye nokusila, ukunyanga kwangaphambili intsimbi ekrwada yegolide ngescreen setrommel linyathelo elibalulekileyo lokuphucula ukusebenza kakuhle kwebeneficiation, ngakumbi kwiintsimbi zegolide ezineoksijini ezinodongwe.

Emva koko, ukukhupha igolide kungenziwa kusetyenziswa iindlela ezinje ngokwahlulahlula amandla angaphantsi komhlaba , i-cyanidatio n, okanye i-heap leaching.

Inyathelo 1: Ukutyumza intsimbi

Ukutyumza kunciphisa ubungakanani begolide ene-oxidized ore kwaye ngokuqhelekileyo kwenziwa ngokusebenzisa inkqubo eyomileyo kunye nezigaba ezimbini ukuya kwezintathu ezilandelelanayo zokutyumza: eziziiprayimari, ezizisekondari, kunye neziphezulu.

Emva kokutyunyuzwa, isikrini esingcangcazelayo sisetyenziselwa ukwahlula intsimbi yegolide eneoxidized. Amasuntswana amancinci adlula kwindawo yokuvuleka kwesikrini ngelixa amasuntswana amakhulu ahlala kumphezulu wesikrini kwaye abuyiselwa ukutyunyuzwa ngakumbi.

Inyathelo lesi-2: Ukugaya i-Ore

Ukusila kukhulula igolide kwiiminerali ze-ganggue kwintsimbi ekrwada ene-oxidized yegolide, oko kudala iimeko ezilungele ukuxhamla okulandelayo. Izixhobo zokugaya eziqhelekileyo ziquka iibhola zebhola kunye neepani ezimanzi.

Inyathelo lesi-3: Uncedo lwentsimbi

Uncedo lwegolide oluxutywe nentsimbi yinkqubo entsonkothileyo nebalulekileyo. Iinkqubo ezahlukeneyo zokukhutshwa zingakhethwa ngokohlobo lwe-ore kunye nefom yegolide. Ezi zilandelayo ziindlela ezininzi eziqhelekileyo zokuzuza:

1. Ukwahlulwa koMxhuzulane

Ukwahlulahlula umxhuzulane yindlela ebonakalayo esebenzisa umahluko kubunzima obuthile phakathi kwegolide ekrwada kunye neeminerali ze-ganggue ukwahlula.

Isixhobo sokwahlula intsimbi ekrwada esetyenziswa ngokuqhelekileyo ibandakanya itafile eshukumayo, i-spiral chute, ijig, njl.

2. I-cyanidation

Indlela ye-cyanidation yeyona ndlela isetyenziswa kakhulu kwimichiza yokutsalwa kwegolide. Ilungele ukumbiwa kwemigodi emincinci naphakathi yeentsimbi ezikrwada zegolide, ngakumbi ezo zinobungakanani bamasuntswana alungileyo kunye nomgangatho ophezulu.

Emva kokusila, i-oxidized gold ore ixutywe nesisombululo se -cyanide , kwaye igolide iyanyibilika kulwelo nge-leaching reaction, ize emva koko igolide ifunyanwe ngokutsalwa kwekhabhoni esebenzayo okanye nge-zinc precipitation.

I-Cyanidation inikezela ngamazinga aphezulu okubuyisela igolide kunye nokusebenziseka okubanzi kodwa kubandakanya imisebenzi enzima kunye neendleko eziphezulu ngenxa yesidingo sokulawula inkunkuma ye-cyanide.

3. Imfumba yokuLeaching

Imfumba yokuvuza ilungele ibakala eliphantsi okanye izigaqa ezinkulu zentsimbi ekrwada ene-oxidized yegolide, rhoqo ngaphandle kokusila kwangaphambili.

Emva kokutyunyuzwa, intsimbi ekrwada ibekwe kwindawo evuzayo - i-proof leaching pad, yenze imfumba yentsimbi. Umxube weCyanide utshizwa phezu kwemfumba ukunyibilikisa igolide, ethi iphinde ibuyiswe kwisisombululo seleach.

Le nkqubo ineendleko zotyalo-mali eziphantsi, ukusebenza okulula, ukuguquguquka okubanzi, kwaye ifanele ukutsalwa komgangatho ophantsi wegolide ekrwada. Nangona kunjalo, ifuna ubungakanani obuthile be-ore, njengoko amasuntswana amahle kakhulu anokuchaphazela ukusebenza kakuhle kwe-leaching.

Ezi zezona ndlela zintathu ziphambili zokusetyenzwa kwentsimbi ekrwada yegolide. Kwi-ores ene-oxidized inxenye, ukwahlulwa komxhuzulane kunye ne-cyanidation zihlala zidityanisiwe. Kwiintsimbi ezikrwada ezixutywe ngokupheleleyo, igolide erhabaxa ubukhulu becala ifunyanwa kusetyenziswa ukwahlula umxhuzulane, ngelixa amasuntswana egolide acokisekileyo anyangwa nge-agitation cyanidation, kunye namasuntswana obungakanani besanti alungiswa ngepercolation cyanidation.

isiphelo

Ukucutshungulwa kwentsimbi ekrwada yegolide kuxhomekeka kubunjani bentsimbi kunye nendlela yegolide. Ngokukhetha ezona ndlela zifanelekileyo zokuxhamla kunye nokwandisa iinkqubo zokutyumza, zokugaya kunye nokwahlula, amazinga okubuyisela igolide anokwandiswa kwaye izibonelelo zoqoqosho ziphuculwe.

Shanxi United Chemical ivelisa umgangatho ophezulu Isodium cyanide ngobuchwepheshe obuphambili kunye nezixhobo. Kwimibuzo yobugcisa enxulumene negolide ye-cyanidation, imfumba ye-leaching, njl., unokuqhagamshelana nathi nangaliphi na ixesha. Sinceda abathengi ukuba bafezekise ukubuyiswa kwegolide ngokufanelekileyo kunye nokuzinza.
