Amanyathelo oKhuseleko lokusiNgqongileyo kwiMigodi yeGolide yaseRashiya usebenzisa iSodium Cyanide yokuThwelwa kweGolide

Kwishishini lemigodi yegolide, ukusetyenziswa kwe sodium cyanide kuba ukutsalwa kwegolide yinto eqhelekileyo. Nangona kunjalo, le nkqubo izisa imingcipheko enokubakho kokusingqongileyo. Imigodi yegolide yaseRashiya ibithatha uthotho lwamanyathelo okukhusela okusingqongileyo ukunciphisa le mingcipheko.

Ulawulo olungqongqo lweSodium Cyanide

Sodium i-cyanide igcinwe kwiindawo ezilungiselelwe ngokukodwa nezikhuselekileyo, ezixhotyiswe ngemiqobo yokukhusela kunye nobushushu - iinkqubo zokulawula ukufuma. Ngexesha lothutho, ilandela imigaqo engqongqo yokuthintela nakuphi na ukuvuza okanye ukuchitheka. Ulawulo lwedosi oluchanekileyo lukwabalulekile. Ngokusebenzisa imifuniselo, ugxininiso olululo lwe Isodium cyanide uzimisele, ngokuqhelekileyo phakathi koluhlu lwe-0.05% - 0.1%, ukuphepha ukusetyenziswa ngokugqithiseleyo, okungandisi nje iindleko kodwa kunye nomngcipheko wongcoliseko lwendalo.

Xa kuziwa ekufumaneni umgangatho ophezulu Isodium cyanide, Shanxi United Chemical ime ngaphandle. Inkampani ayinikezeli kuphela i-sodium cyanide ephezulu kodwa ikwabonelela ngenkxaso yobugcisa ebanzi kunyango lwenkunkuma ye-sodium cyanide. Ubungcali babo bunokuba yi-asethi enkulu kwimigodi ejolise ekusebenzeni ngokufanelekileyo. Ngokukhetha Shaanxi United Chemical, imigodi inokungenelwa kwizinto ezinokuthenjwa kunye nezisombululo zobugcisa, ezinegalelo ekusebenzeni kakuhle kwayo yonke inkqubo yokukhutshwa kwegolide.

Unyango lwamanzi amdaka

Unyango lwe-Oxidation

I-Chemical oxidation okanye iindlela ze-biological oxidation zisetyenziselwa ukuguqula iicyanides emanzini amdaka kwizinto ezinetyhefu encinci okanye ezingenayo ityhefu. Umzekelo, ngokongeza ii-oxidants ezinamandla, IiCyanides inokubola ibe zizinto ezingenabungozi njengekharbon diokside nenitrogen.

Unyango lokungathathi hlangothi

Ixabiso le-pH lamanzi amdaka lilungelelaniswa ukuba lingathathi hlangothi okanye likufutshane - lithintele amanzi amdaka aneasidi okanye anealkali ekungcoliseni indalo esingqongileyo. Oku kukwanceda ukuqumba nokususa ii-ion zentsimbi enzima.

ebesezisetyenzisiwe

Inkqubo yokurisayikilisha yesisombululo isekiwe ukuze kusetyenziswe ngokuqhubekayo isisombululo secyanide. Oku kuphucula ukusetyenziswa kobutyebi kwaye kunciphisa isixa sisonke samanzi amdaka alahlwayo.

Ulawulo lwemisila

IZibonelelo eziZodwa zokuGcina

Iintsalela zezimbiwa zigcinwa kumadama eentsalela zezimbiwa eziyilwe ngokukodwa, amadama, okanye iindawo zokugcina ezineempawu ezibalaseleyo zokuchasa ukuvuza. Oku kuthintela i-leachate ene-cyanides ekungeneni emhlabeni nakumanzi aphantsi komhlaba.

Ukusetyenziswa kweeTekhnoloji zoNyango lweeTailings zale mihla

Itekhnoloji enje ngoxinaniso lwee-tailings kunye nokucoca zisetyenziselwe ukunciphisa ukufuma kunye nomxholo we-cyanide kwi-tailings, ukunciphisa umngcipheko ohambelana nokugcinwa kwee-tailings kunye nokwenza kube lula ukulawula nokulahla.

Ukhuseleko lweSiza

Ukusetyenziswa kwe-Anti-Leakage Liners

Ii-anti-leakage liners, ezifana ne-polyurea coatings, zibekwe phantsi kunye nemigangatho yangaphakathi yezixhobo kwiindawo apho kugcinwa khona i-sodium cyanide, kwiitanki ezivuzayo, kunye namadike e-tailings. Oku kuthintela iicyanides ukuba zingavuzi emhlabeni namanzi aphantsi komhlaba.

Ufakelo lweeNkqubo zoKhuseleko lweSibini

Ukongeza kwii-anti-leakage liners eziphambili, iinkqubo zokukhusela zesibini zisekiwe, ezifana nokumisela i-cofferdams kunye neetanki zokuqokelela malunga neendawo zokugcina. Oku kuvumela ukuqokelelwa kwangethuba kunye nonyango lweecyanides ezivuzayo kwimeko yengozi.

Ukongamela imeko yendalo

Ukufunyanwa rhoqo

Ukujongwa rhoqo kwamanzi amdaka, umhlaba, umoya, kunye namanzi ajikelezileyo kuqhutyelwa ukukhangela umxholo we-cyanides kunye nezinye izinto ezingcolileyo. Oku kuqinisekisa ukuba zonke izalathisi ziyahlangabezana nemigangatho yokukhuselwa kokusingqongileyo kwaye zenze ukuba kufunyanwe kwangethuba kunye nokusingatha iingxaki ezinokuba khona zongcoliseko.

Real - Ixesha Online Monitoring

Izixhobo zokubeka iliso kwi-Intanethi zifakwe kwiindawo eziphambili ukujonga iiparamitha eziphambili ezifana nokugxininiswa kwe-cyanide kunye nexabiso le-pH ngexesha langempela. Nje ukuba iimeko ezingaqhelekanga zenzeke, ii-alam zinokukhutshwa ngokukhawuleza, kwaye amanyathelo anokuthathwa ngokukhawuleza.

Ulawulo noVavanyo

Uvavanyo lwempembelelo kokusiNgqongileyo

Ngaphambi kokuphunyezwa kweeprojekthi zemigodi yegolide, uvavanyo olubanzi lwempembelelo yokusingqongileyo luyenziwa. Imingcipheko enokubakho yendalo ebangelwa kukusetyenziswa kwe-sodium cyanide ihlalutywa, kwaye amanyathelo ahambelanayo okuthintela kunye nokunciphisa aqulunqwa.

Ukuthotyelwa kweMimiselo kunye nokuLongamela

Imigodi yegolide yaseRashiya ithobela ngokungqongqo imithetho yasekhaya neyamazwe ngamazwe kunye nemigangatho ephathelele ukusetyenziswa kweecyanides nokhuseleko lwendalo esingqongileyo. Bavuma ukubeka iliso kunye nokuhlolwa okuvela kumasebe karhulumente afanelekileyo ukuqinisekisa ukuphunyezwa kwawo onke amanyathelo okukhusela okusingqongileyo.

Ukuqukumbela, imigodi yegolide yaseRashiya yenze iinzame ezimangalisayo kukhuseleko lwendalo esingqongileyo ngexesha lenkqubo yokusebenzisa i-sodium cyanide ukutsalwa kwegolide. La manyathelo awakhuseli nje okusingqongileyo kuphela kodwa akwaqinisekisa uphuhliso oluzinzileyo lweshishini lemigodi yegolide. Ngaphezu koko, kunye namaqabane afana noShaanxi United Chemical, imisebenzi yokwembiwa kwegolide inokusebenza kakuhle kwaye inobungani nokusingqongileyo.
