Doorka Hydrogen Peroxide ee Nidaamyada Leaching Sodium Cyanide

Hordhac

Dhinaca soo saarista dahabka iyo birta kale - hababka soo kabashada, cyanide leaching, gaar ahaan leh sodium cyanide, waxa uu ahaa hab si weyn loo isticmaali jiray in ka badan qarni. Habkan, kaas oo abuura birta milmi - cyanide dhismayaal, waa wax ku ool ah laakiin waxay wajahaan caqabado dhowr ah. Mid ka mid ah arrinta ugu weyn ayaa ah xawaaraha falcelinta oo yara gaabis ah iyo baahida loo qabo sahayda ogsijiinta oo ku filan si ay u milmaan biraha sida dahabka ah. Tani waa meesha hydrogen peroxide (H.

Aasaaska Cyanide Leaching

Cyanide leaching wuxuu shaqeeyaa sababtoo ah ion cyanide waxay la falgali karaan biraha si ay u sameeyaan dhismo xasilan oo milmi leh. Marka ay timaado soo saarista dahabka, ogsijiinta ayaa door muhiim ah ka ciyaara sida wakiilka oksaydhka. Waxay ka caawisaa in ay dahabka u beddesho qaab isku dari kara ion cyanide, taas oo keeneysa iskudhaf milmaya oo si dheeraad ah looga baaraandegi karo si loo helo dahab. Si kastaba ha ahaatee, macdano badan, ogsijiinta dabiiciga ah ee laga helo hawada inta badan kuma filna. Yaraantani waxay keentaa falcelin gaabis ah iyo soo saarid bir ah oo aan dhamaystirnayn.

Sida Hydrogen Peroxide ay uga caawiso Leaching Cyanide

1. Ogsajiinta

Hydrogen peroxide waa walax oxidizing awood leh. Marka lagu daro xalka leaching cyanide, wuu jabaa oo soo daayaa ogsijiinta. Ogsajiintan dheeriga ah waxay si weyn u kordhisaa oksaydhka biraha inta lagu jiro habka dheecaanka. Macdanta ay ku jiraan macdanaha sulfide, tusaale ahaan, oksaydhaynta sulfides-ka oksijiinta ayaa muhiim u ah xoraynta dahabka ku jira. Ogsajiinta uu sii daayo hydrogen peroxide waxay soo dadajin kartaa tallaabadan oksaydheynta, taasoo u sahlaysa cyanide in uu hadhow uga falceliyo dahabka.

2. Dardar gelinta Heerka Leaching

Daraasaduhu waxay muujiyeen in hydrogen peroxide ay kordhin karto xawaaraha guud ee habka dheecaanka cyanide. Kaliya ma bixiso ogsijiin dheeraad ah; waxa kale oo ay ka qayb qaadataa falcelinta kiimikaad ee jebisa lakabyada difaaca ee dusha sare ee qaybaha macdanta. Mararka qaarkood, sulfide birta ah ama macdanaha kale waxay sameeyaan lakab dahab ah - qaybo sita, taas oo ka joojisa cyanide inay gaarto dahabka. Hydrogen peroxide waxay ka falcelin kartaa lakabyadan, ha ahaato iyaga oo oxidizes ama jir ahaan kala jajabiya iyada oo loo marayo ficilka xagjirnimada xorta ah ee la soo saaro inta lagu jiro burburka. Tani waxay u oggolaanaysaa ion cyanide inay si sahal ah u galaan dahabka, sidaas awgeed waxay kordhinaysaa heerka lagu kala diri karo dahabka.

3. Yaraynta Isticmaalka Cyanide

In leaching cyanide dhaqameed, xaddi badan oo cyanide ah loo isticmaalo ma aha oo kaliya in falcelinta dahabka, laakiin sidoo kale in falcelin dhinaca la ion biraha kale ee ku jira macdanta, sida copper, zinc, iyo birta. Dareen-celinta dhinacyadu waxay yareeyaan waxtarka dahabka - falcelinta cyanide waxayna kordhiyaan kharashka guud ee habka leaching. Hydrogen peroxide waxay kaa caawin kartaa dhimista isticmaalka cyanide laba siyaabood. Marka hore, adoo kor u qaadaya oksaydhka dahabka, waxay kor u qaadaysaa samaynta dahabka - cyanide complex si dhakhso ah, taasoo ka dhigeysa waqti yar oo cyanide ah si ay ula falgasho biraha kale. Marka labaad, hydrogen peroxide waxay bedeli kartaa qaabka qaar ka mid ah ions birta ah ee farageliya si ay uga falceliyaan cyanide. Tusaale ahaan, waxa ay u rogi kartaa ion ferrous ion. Iions Ferric waxay sameeyaan dhismayaal aan xasiloonayn oo leh cyanide, taas oo yaraynaysa cadadka cyanide ee ku luminaya falcelinta dhinaca aan waxtarka lahayn.

Daraasadda Kiis iyo Caddaymaha Tijaabada

Tijaabooyin shaybaar oo badan iyo tijaabooyin warshadeed ayaa caddeeyey waxtarka hydrogen peroxide ee leaching cyanide. Mid ka mid ah daraasadda adag - in la farsameeyo macdanta dahabka, ku darista hydrogen peroxide xalka leaching cyanide waxay kordhisay heerka leaching dahabka 20 - 30% marka loo eego leaching dhaqameed ee cyanide ah oo leh hawo kaliya. Wakhtiga wax-ka-saarista ayaa sidoo kale si weyn hoos loogu dhigay, laga bilaabo dhawr maalmood ilaa dhawr saacadood oo keliya.

Codsiga macdanta dahabiga ah ee cabbirka warshadaha, iyadoo la isticmaalayo hydrogen peroxide ee habka leaching cyanide waxay keentay hoos u dhac 15% ah isticmaalka cyanide iyadoo weli la ilaalinayo heerka soo kabashada dahabka sare. Tani kaliya hoos uma dhigin kharashyada hawlgalka ee la xidhiidha iibsashada cyanide laakiin sidoo kale waxay yaraysay khataraha deegaanka ee la xidhiidha isticmaalka iyo tuurista cyanide.

Tixgelinta Isticmaalka Hydrogen Peroxide

1. Xoog-saarid

Qadarka ugu fiican ee hydrogen peroxide si loogu daro xalalka cyanide-ka ayaa ku xiran arrimo kala duwan, oo ay ku jiraan nooca macdanta, fiirsashada cyanide ee horeba xalka, iyo joogitaanka macdanta kale. Guud ahaan, inta u dhaxaysa 0.1 - 1% (mugga) ayaa la ogaaday inay si fiican u shaqeyso xaaladaha intooda badan. Laakin haddii fiirsigu aad u sarreeyo, waxay keeni kartaa in ka badan - oksaydheynta biraha, oo ay ku jiraan dahabka. Tan oksaydhation-ka ayaa laga yaabaa inay abuurto xeryahooda dahabka ah ee aan milmi karin waxayna yaraynaysaa cadadka dahabka ah ee la soo celin karo.

2. Xakamaynta pH

Heerka pH ee xalinta dareeraha ayaa aad muhiim u ah marka la isticmaalayo hydrogen peroxide. Leaching cyanide sida caadiga ah waxay ku dhacdaa pH sare (qiyaastii 9 - 12) si looga hortago samaynta gaasta hydrogen cyanide sunta ah. Hydrogen peroxide aad ayey ugu xasilloon tahay qiyamka sare ee pH. Si kastaba ha noqotee, haddii pH-gu uu aad u sarreeyo, waxay yarayn kartaa waxtarka hydrogen peroxide sida wakiilka oksida. Sidaa daraadeed, xakamaynta taxadarka leh ee pH ayaa loo baahan yahay si loo hubiyo in labadaba cyanide iyo hydrogen peroxide ay si fiican ugu shaqeeyaan nidaamka leaching.

3. Ammaanka

Hydrogen peroxide waa walax oksaydhiye ah oo xooggan waxayna noqon kartaa khatar haddii aan si sax ah loo qaban. Waxay ka xanaajin kartaa maqaarka iyo indhaha, iyo qaababka xoogga leh, waxay xitaa noqon kartaa qaraxyo. Markaad isticmaalayso hydrogen peroxide ee leaching cyanide, tillaabooyinka badbaadada saxda ah waa in lafuliyaa. Tan waxaa ka mid ah isticmaalka qalabka ilaalinta shakhsi ahaaneed, kaydinta iyo maaraynta kiimikada si habboon.

Ugu Dambeyn

Hydrogen peroxide waxay muujisay karti weyn sida wax lagu daro Sodium cyanide hababka leaching. Iyadoo la siinayo ogsijiin dheeraad ah, dedejinta heerka dheecaanka, iyo yaraynta isticmaalka cyanide, waxay kor u qaadi kartaa waxtarka iyo dhaqaalaha dhaqaale ee soo saarista birta, gaar ahaan dahabka. Si kastaba ha ahaatee, sida hab kasta oo kiimiko ah, hagaajinta saxda ah iyo u hoggaansanaanta adag ee borotokoolka badbaadada ayaa lagama maarmaan u ah hirgelintiisa guusha leh. Maaddaama warshadaha macdanta ay sii wadaan inay raadiyaan habab wax soo saar oo waxtar leh oo waara, isticmaalka hydrogen peroxide ee leaching cyanide waxay u badan tahay inay noqoto mid aad muhiim u ah mustaqbalka.
