1. Kwalite usoro ịhịa aka n'ahụ

The usoro leaching bụ ebe sodium cyanide na-emekọ ihe na ore iji gbazee ọla ndị e lekwasịrị anya. Site n'ịkwalite oke n'ime usoro a, enwere ike nweta mbelata dị ukwuu na ojiji cyanide.

1.1 Fine-Tune pH na Ọkwa Oxygen

Sodium cyanide na-arụ ọrụ nke ọma n'ime otu pH dị iche iche, nke na-adịkarị n'etiti 10 na 11. Nleba anya na ịchịkwa pH nke ngwọta leaching nwere ike ịkwalite mmeghachi omume nke cyanide. Ọzọkwa, oxygen dị oké mkpa maka mmeghachi omume oxidation nke na-eme ka mgbaze ígwè. Igwe ikuku zuru oke, site na ụzọ dị ka iji ikuku compressors ma ọ bụ sistemu injection oxygen, na-ahụ na usoro oxidation na-aga nke ọma. Site n'ịkwado nguzozi ziri ezi nke pH na oxygen, obere cyanide dị mkpa iji nweta otu ọkwa nke mmịpụta ígwè.

1.2 Were ụzọ ọgwụgwọ tupu ọgwụgwọ

Ịmezi ígwè ahụ tupu oge eruo nwere ike ime ka ọ dịkwuo mfe iji cyanide leaching, na-ebelata ihe achọrọ cyanide n'ozuzu ya. Dịka ọmụmaatụ, ịsa nri ma ọ bụ bio-oxidation nwere ike ịkụda ihe ndị na-emegharị ihe na ore, na-ekpughere ọtụtụ ọla ndị a na-achọsi ike na ngwọta cyanide. Nrụgide oxidation bụ ụzọ ọzọ dị irè tupu ọgwụgwọ, nke nwere ike ime ka akụkụ elu nke ihe ndị na-emepụta ihe dịkwuo elu ma melite kọntaktị dị n'etiti cyanide na ọla, si otú a na-eme ka ọnụego mgbake na-eji obere cyanide.

2. Mepụta ihe ọhụrụ na ihe ndị ọzọ reagents na mgbakwunye

Ịchọgharị reagents ọzọ na ihe mgbakwunye nwere ike inye ihe mgbakwunye ma ọ bụ mgbakwunye na sodium cyanide, na-ebelata ịdabere na ya.

2.1 Jiri ndị ọrụ nkuzi na-enweghị Cyanide

Ọtụtụ ihe nzacha cyanide apụtala dị ka ihe ọzọ nwere ike ime. Dịka ọmụmaatụ, Thiosulfate egosila nkwa na mmịpụta ọla edo. Ọ dị obere na-egbu egbu karịa sodium cyanide ma nwee ike nweta ọnụego mgbake yiri ya n'okpuru ọnọdụ kwesịrị ekwesị. Thiosulfate leaching na-arụ ọrụ nke ọma na mmanụ ndị nwere nnukwu ọla kọpa ma ọ bụ ihe ndị ọzọ na-etinye aka, nke nwere ike iri cyanide na usoro omenala. Nhọrọ ọzọ bụ thiourea, nke na-enyekwa ihe mgbakwunye gburugburu ebe obibi maka mmepụta ígwè, karịsịa mgbe ejikọtara ya na oxidants kwesịrị ekwesị.

2.2 Tinye mgbakwunye

Ihe mgbakwunye nwere ike ịkwalite arụmọrụ sodium cyanide, na-enye ohere iji belata ojiji. Dịka ọmụmaatụ, a na-ejikarị wayo na-edozi pH nke ngwọta leaching ma gbochie ịmepụta gas cyanide hydrogen na-emerụ ahụ. Na mgbakwunye, ụfọdụ polymers na surfactants nwere ike melite mgbasa nke cyanide na slurry ore, na-abawanye arụmọrụ kọntaktị n'etiti cyanide na ọla. Ihe mgbakwunye ndị a nwere ike inye aka belata oriri cyanide ruo 20-30% ka ị na-ejigide ọnụego mgbake.

3. Melite akụrụngwa na usoro nlekota oru

Ịkwalite akụrụngwa na itinye usoro nleba anya dị elu nwekwara ike inye aka n'ibelata ojiji sodium cyanide.

3.1 Nweta nkwalite Leaching Reactors

Igwe ọkụ na-agbapụta n'oge a, dị ka igwe ọkụ na-agbagharị agbagharị nwere usoro ịgwakọta ka mma, nwere ike hụ na nkesa cyanide dị n'otu n'ime slurry ore. Nke a na-eme ka arụmọrụ nke mgbasa ígwè dịkwuo mma, na-enye ohere iji obere cyanide mee ihe. Ndị na-eme mkpọtụ na-aga n'ihu (CSTRs) nwere atụmatụ impeller kachasị mma nwere ike ịkwalite ọnụego mbufe oke, na-ebelata oge na ego nke cyanide chọrọ maka mmepụta ígwè zuru oke.

3.2 Mejuputa nlekota oru oge

Igwe ihe mmetụta dị elu na sistemụ nleba anya nwere ike na-aga n'ihu tụọ paramita dị ka mkpokọta cyanide, pH, na ọnụego mgbasa igwe na usoro ịhịa ahụ. Site n'inwe data ozugbo, ndị na-arụ ọrụ nwere ike ime mgbanwe ozugbo na usoro cyanide, hụ na ọ bụ naanị ego dị mkpa na-eji. Enwere ike ijikọ sistemu njikwa akpaaka na ihe mmetụta ndị a iji mezie mgbakwunye cyanide nke ọma, na-egbochi ịfefefefe oke na ịkwalite ọnụego mgbake.

4. Hazie njikwa na nkwadebe mmanụ

Proper ejizi ore na nkwadebe nwere ike inwe mmetụta dị ukwuu na ojiji cyanide na ọnụego mgbake.

4.1 Mbulite igwe ọka

Ijikwa urughuru nha nke ore site na nke kachasị egweri dị mkpa. Ogo urughuru mma na-abawanye ebe elu dị maka cyanide iji meghachi omume na ọla ndị ahụ, mana oke egweri nwekwara ike iduga ụbara oriri reagent. Site n'ịchọta nkesa kacha mma urughuru size site nnwale na usoro simulations, ego nke cyanide mkpa maka irè metal mmịpụta nwere ike ibelata mgbe ịnọgide na-enwe elu mgbake ọnụego.

4.2 Teknụzụ nhazi nke ore

Ịmejuputa teknụzụ nhazi ore, dị ka nhazi X-ray fluorescence (XRF) ma ọ bụ nhazi anya, nwere ike ikewapụ ore dị elu na ore obere ọkwa tupu usoro ịsa ahụ. Nke a na-enye ohere maka ịsacha akụkụ ndị bara uru karịa nke ore, na-ebelata mkpokọta ihe onwunwe nke achọrọ iji cyanide na-agwọ ya wee si otú a na-ebelata oriri cyanide.

N'ikpeazụ, ibelata iji sodium cyanide eme ihe mgbe ị na-ejigide ọnụego mgbake bụ ihe ịma aka dị iche iche nke na-achọ nchikota nke njikarịcha usoro, mmepụta nkà na ụzụ, na nlezianya na-arụ ọrụ. Site n'itinye atụmatụ ndị ahụ akọwapụtara n'elu, ụlọ ọrụ na-egwupụta akụ na igwe nwere ike ọ bụghị naanị ibelata akara ukwu gburugburu ebe obibi ha kamakwa nwere ike belata ụgwọ ọrụ n'ime ogologo oge. Ka nyocha na-aga n'ihu na-aga n'ihu, ụzọ ọhụrụ na nke dị irè nwere ike ịpụta, na-emewanyewanye nkwado nke usoro mmepụta ígwè.
