Amagcisa axoxa ngendima yeSodium Cyanide ekuThweni kweGolide

Okokuqala, ukukhutshwa kwegolide ye -cyanide sodium , okwaziwa ngokuba yi-cyanide leaching, yinkqubo esele imiselwe ixesha elide. Okwangoku, phantse i-30% yegolide yehlabathi ikhutshwa ngale ndlela, nto leyo ebonisa ukusetyenziswa kwayo ngokubanzi.

Izinto eziluncedo: Iindleko eziphantsi kunye neleaching esebenzayo.

Izinto ezingeloncedo: Imiba yokusingqongileyo.

Ngapha koko, inkqubo ye-cyanide pool leaching yesiko kudala idweliswe ukupheliswa. Kule mihla, uninzi lweendlela zibandakanya i-cyanide heap leaching okanye i-in-situ leaching, kodwa ezi zikwakhutshwa ngokuthe ngcembe, njengoko okwangoku kungekho teknoloji ingcono yokuthatha indawo yazo.

I-sodium cyanide inetyhefu kakhulu, ngoko ke ulawulo olungqongqo kunye nolawulo luyafuneka ngaphambi nangemva kokusetyenziswa kwayo.

Makhe ndishwankathele inkqubo yokulungiswa kwezimbiwa (okanye ukuxhamla). Esi sihloko sinokubonakala sikude kuluntu jikelele, njengoko abantu abaninzi bengazi ukuba emva kokuba i-ore imbiwe, kufuneka idlule kwinqanaba lokulungisa izimbiwa. Emehlweni omntu oqhelekileyo, intsimbi igrunjwa ize inyibilikiswe ngokuthe ngqo ibe yintsimbi, akunjalo? Nangona kunjalo, le ngcamango ayichanekanga ngokupheleleyo. Uninzi lweendawo ezikrwada zinomgangatho ophantsi kwaye ziqulathe ubumdaka obuninzi, nto leyo ezenza zingakulungeli ukunyibilikiswa ngokuthe ngqo. Ukongeza, ubukho bobumdaka obuninzi buyenza ibe nzima inkqubo yokunyibilikisa, kwandisa iindleko, kwaye kubangele iimveliso ezikumgangatho ophantsi. Ngoko ke, kukho inyathelo elifunekayo lokulungiswa kwamaminerali phakathi kwemigodi kunye nokunyibilika.

Umzekelo, ukuba wemba intsimbi ekrwada ngomxholo we-iron (ibakala) wama-40%, ukuyinyibilikisa ngokuthe ngqo kunokukhokelela kukungcola okuyingozi okufana ne-phosphorus, nto leyo eyenza ukuba intsimbi ibe brittle. Yintoni enokwenziwa? Intsimbi ekrwada inokucutshungulwa ukwandisa umxholo wentsimbi ukuya kuma-60% ngeendlela ezinjengokwahlulwa komxhuzulane, ukwahlukana kwamagnetic, kunye nokusila, okukhokelela kwi-60% ye-iron concentrate. Oku kugxilwa kwentsimbi kuye kwasuswa ukungcola kwaye kunokusetyenziswa ngokuthe ngqo ukunyibilikisa.

Ngokufanayo, ii-ores ezifana nelothe, i-zinc, i-copper, i-molybdenum, kunye ne-nickel nazo zifuna ukusetyenzwa kweeminerali ukugxila kwiiminerali ezixabisekileyo kunye nokususa ukungcola, ukubonelela ngemathiriyeli ekrwada efanelekileyo yokunyibilikisa.

Kule ngcaciso ingentla, umntu kufuneka aqonde imfuneko yokulungiswa kwezimbiwa. Kuthekani ngentsimbi yegolide?

Kakade ke, intsimbi yegolide nayo ifuna ukulungiswa kwezimbiwa.

Ii-ore ze-lead-zinc eziqhelekileyo zihlala zinezinga elidibeneyo elimalunga ne-5% okanye ngaphezulu, ezinye ii-ore ezikumgangatho ophantsi zimalunga ne-2%. Nangona kunjalo, i-ore yegolide yahlukile. Izinga le-ore yegolide lilinganiswa ngeegrama ngetoni (g/t). Ii-ore ezininzi zegolide zinezinga le-1 g/t okanye i-2 g/t kuphela, oko kuthetha ukuba kwitoni enye ye-ore yegolide, kunokubakho i-1 gram okanye ii-2 gram zegolide kuphela. Le golide ikhutshwa njani? Ihlala isetyenziswa kusetyenziswa i-cyanide, enyibilikisa igolide kwi-ore, kwaye emva koko i-activated Carbon isetyenziselwa ukufunxa nokukhupha igolide, nto leyo ephumela kwi-sludge yegolide enokucoca ibe ziibhari zegolide. Inkqubo ye-cyanide okwangoku yeyona ndlela ingabizi kakhulu kwaye ingabizi kakhulu.

Ingaba ikhona enye into enokunyibilikisa igolide ize ithathe indawo yecyanide?

Enyanisweni, zininzi izinto ezinokunyibilikisa igolide, kodwa ukufumana enye indlela echanekileyo endaweni yeSodium cyanide kunzima kakhulu.

I-Thiourea inokunyibilikisa igolide, kodwa idosi efunekayo inkulu kakhulu, iyenza ibize kakhulu!

I-Polysulfides kunye ne-lime sulfur nazo zingasetyenziswa, kodwa zifuna i-copper ammonia ion, kwaye i-dosage iphezulu ngokufanayo, ekhokelela kwiindleko eziphezulu.

Kukho iindlela zebhayoloji leaching, kodwa ezi zisekwinqanaba lovavanyo.

Ezona ndlela zisetyenziswa kakhulu zii-leaching agents ezintsha ezifana ne-JINCHAN kunye ne-JINFU. Ingaba ezi arhente zine-cyanide kuyaphikiswana ngayo, kwaye ukusebenza kwazo kukwangumbandela wengxoxo. Eminye imigodi sele izisebenzisile kwaye zineziphumo ezilungileyo, kodwa ukukhuthazwa okukhulu okanye ithemba lokuba zinokusetyenziswa ngokubanzi njengeSodium Cyanide kwimigodi emininzi yegolide kusenzima kakhulu.

Ngoko ke, inkqubo ye-cyanide ihlala iyindlela eqhelekileyo.

Iiarhente zokukhupha i-cyanide okanye iinkqubo eziveliswe ngabaphandi ekucutshungulweni kwezimbiwa zijongene nemingeni emikhulu ekukhuthazeni nasekuxhaseni amasebe afanelekileyo, nto leyo eyenza kube nzima ukuyisebenzisa ngokubanzi. Kaloku, abo bakwishishini bayazi ukuba i-sodium cyanide iyasebenza, kulula ukuyisebenzisa, kwaye ixabisa kancinci—ngubani ongafuniyo ukufumana inzuzo engaphezulu?

Ukutshintsha inkqubo yecyanide, kunzima ngaphandle kwenkxaso yesizwe eyomeleleyo yokunyuselwa okanye inkxaso-mali yophando olunxulumeneyo.

Ngaba kuyinyaniso ukuba iinkqubo ze-cyanidation, ekubeni ziqhelekileyo, kufuneka zonakalise indalo?

Amazwe anemigaqo-nkqubo eyahluka-hlukeneyo yokukhusela indalo esingqongileyo, kwaye kukho iindlela zokunyanga ezingqongqo kunye nemimiselo yamanzi amdaka emigodini, izisombululo zokuvuza, kunye neentsalela zenkunkuma.

Enyanisweni, ingaba yingozi kangakanani i-sodium cyanide? Liyinyaniso elokuba ukuseza kunokubulala. Nangona kunjalo, inokunyangwa; ngokongeza i-bleaching powder, inokubola ngokuphendula kwe-redox. Amazwe amaninzi anemigaqo-nkqubo, imimiselo kunye nemigangatho efanayo yokulawula lo mbandela.
