Incamake ya Synthesis Uburyo bwa Gold Bubidukikije

Mugihe igihugu cyita cyane ku kurengera ibidukikije, bigomba kuba akazi gashinzwe guharanira inyungu z'icyatsi kibisi n'imbaraga zisukuye zo kurengera ibidukikije bishinzwe kurwanya ibidukikije kugenzura no kugenzura umwanda wibidukikije. kwibanda. Hamwe niterambere rihoraho ryikoranabuhanga ritunganya imyunyu ngugu, zahabu (ibyuma bitari Fyuma) abakozi batunganya kandi bahora bamenyerejwe kandi bashya. Abakozi bake muri uburozi n'abakozi ba zahabu bakurangiza ibidukikije bagamije gusimbuza sodium cyanide barimo kumera mu gihugu hose. Ibikoresho byingenzi byabakozi ni: Biteguwe na Thiocyate, Thiourea, Urea nandi reage yimiti yongeweho na soda ya Caustic. Ugereranije na cyanide gakondo, ifite uburozi buke kandi ifite umutekano gukoresha. Ni ngombwa cyane kuri zahabu (icyuma kidasekeje) umusaruro no kurengera ibidukikije.

Uburyo bwa synthesis bwo gutanga uburozi buke kandi bwa zahabu butangaje bwa zahabu akoresheje urea, soda ya caustic nkuko ibikoresho nyamukuru byibanze bivuga muri make kuburyo bukurikira:

Uburyo 1: Shyushya Urea ash ivu kuri leta yashongeshejwe muri make, ongeraho sodium yumuhondo (potasiyumu), ikangura no gushonga, kumenagura na paki; Ibicuruzwa byarangiye kuri ubu buryo byasesenguwe na X-ray biratandukanye kugirango umenye niba byagenze mubihe bitandukanye. Icyiciro cyumubiri cyibicuruzwa, ibisubizo byerekana ko: Umukozi woherejwe wa zahabu akubiye muri poasisiyumu yumuhondo, Urea na Soda Ish, Cementite (Fe3C), kandi icyiciro gishya ni nabyo byatanzwe. Koresha gusa ntanubwo cyangwa byombi byavuzwe haruguru bitarenze bitatu byavuzwe haruguru birashobora gukora icyiciro gishya. Kubera ko ibindi byiciro byose bidashobora gushinga zahabu, icyiciro gishya gishobora kuba cyarakoze nka zahabu ya zahabu. Kubwibyo, kubana batatu bashya poassiyumu amaraso yumuhondo, urea na soda ivu ni ibintu bikenewe kuri synthesis ya zahabu nziza ya zahabu ikubiyemo icyiciro gishya kirimo icyiciro gishya. Ubushyuhe bworoshye bwubu buryo bugira ingaruka zikomeye ku ngaruka zo gukara no gushiraho ibyiciro bishya. Iyo ubushyuhe burenze 550 ° C, impapuro nshya yicyiciro, ariko kuri 800 ° C, icyiciro gishya kirashira, kandi icyiciro gishya kirashobora kudacogora. Ubu buryo bukoresha umunyu wamaraso yumuhondo na potasiyumu bihenze kandi bifite umubare munini winjiza, bikaviramo amafaranga menshi.

Uburyo 2: Ubushyuhe Urea, Soda Ash, umusemburo, hamwe nubugizi bwa nabi, bakomeza gushyuha mugihe runaka, bakomeza gushyuha mugihe runaka, gusohora no gukonjesha, gukonja na paki; Ubu buryo bukoresha kandi Urea na Soda ivu nkibikoresho byibanze byibanze, ariko wongeyeho umusemburo birashobora guteza imbere reaction ku bushyuhe buciriritse kandi buke. Muri icyo gihe, abayabujijwe bongerewe mugihe cya synthesis kugirango babuze ibicuruzwa kubora mu bushyuhe bwinshi kandi bigatera imibura mishya, amaherezo bigira ingaruka kumiterere no gutuza kubicuruzwa. X-ray isesengura ryibicuruzwa byarangiye kuri ubu buryo irashobora kandi guhishura ibyiciro bishya bishobora kugira uruhare muri zahabu. Igiciro cyubu bwoko kiratandukanye, ibikubiye mubintu bifatika mubicuruzwa bigenzurwa, kandi ibikubiye mubintu bifatika birarenze ubwo buryo.

Uburyo butatu: Reba Urea, soda ash, no kugabanya umukozi muri leta yashongeshejwe. Nyuma yimyitwarire irangiye, ikonje, guhonyo na paki. Ubu buryo muburyo bwo gukoresha Urea na Soda Ivu kugirango babone ubushyuhe runaka kugirango bakomatane sodium cyanate. Kugabanya abakozi nkifu yicyuma no kugabanya ifu ya karuboni irashobora kugabanya sodium cyanate muri sodium yuburozi cyane. Ubu buryo bugabanuka-buke kandi burashobora guhagarika imirongo myinshi. Isesengura rya X-Ray risobanura ko nta cyiciro gishya gishinzwe gukorwa, cyane cyane sodium cyanide.

Ibikoresho nyamukuru byibanze byuburyo butatu bwa Urea na Soda ivu. Uruvange rwa soda ash na sodium cyanate narwo rushobora kandi gukoreshwa nkibikoresho fatizo byifatiro kugirango wirinde gaze ya ammomiya yabyaye uko yabyitwayemo kwanduza ibidukikije. Ibikoresho byifashe muburyo butatu ni kimwe, nubushyuhe bwinshi bwitanura cyangwa amavuta ya mazutu birashobora gukoreshwa. Cyangwa gaze yahise ihindura umusaruro.
