Ubwino Waikulu wa Sodium Cyanide Mulu Leaching kwa M'zigawo Golide

Kuchotsa mchere wa sodium cyanide mulu wa miyala ndi njira yomwe imagwiritsidwa ntchito kwambiri mumakampani opanga golide pochotsa golide kuchokera ku miyala yamtengo wapatali. Njirayi imaphatikizapo kuunjika miyala yamtengo wapatali ya golide kapena mipata yoyandama pa chinthu chopangidwa ndi dothi ndikupopera yankho la cyanide pamwamba pa muluwo kuti golide ndi siliva zisungunuke, ndikupanga yankho lokhala ndi golide kuti libwezeretsedwe pambuyo pake. Nazi zabwino zazikulu za njira iyi:

Mtengo - kuchita bwino

1. Ndalama zochepa: Chimodzi mwa zabwino kwambiri za Sodium cyanide heap leaching ndichakuti imafuna ndalama zochepa. Poyerekeza ndi njira zovuta kwambiri zopezera golide monga kugaya ndi kusungunula golide mwachizolowezi, zomwe zimafuna zomangamanga ndi zida zambiri, heap leaching imangofunika zinthu zoyambira monga leaching pad, njira yosonkhanitsira mayankho, ndi njira yoyendetsera mayankho. Palibe chifukwa chomangira mafakitale akuluakulu komanso okwera mtengo, zomwe zimapangitsa kuti ikhale njira yokongola, makamaka pantchito zazing'ono mpaka zapakatikati kapena malo osungira migodi omwe ali ndi ndalama zochepa.

2.Kuchepetsa ndalama zogwirira ntchito:

• Kugwiritsa ntchito mphamvu zochepa: Njira yochotsera miyala mu heap leaching imafuna mphamvu zochepa. Sizimafuna mphamvu zambiri monga kupukusa miyala kukhala ufa wabwino mu mphero, zomwe zimachitika kawirikawiri m'njira zina zochotsera miyala. Kugwiritsa ntchito mosavuta njira yopopera ndi kufalitsa madzi mu heap kumafuna mphamvu zochepa, zomwe zimapangitsa kuti ndalama zamagetsi zichepe.

• Mtengo wotsika wa reagent (poyerekeza ndi njira zina): Ngakhale kuti cyanide ndi reagent yofunika kwambiri ndipo kugwiritsidwa ntchito kwake kumafuna njira zodzitetezera kwambiri, pankhani ya njira yonse yochotsera golide, kuchuluka kwa cyanide komwe kumafunika pochotsa golide m'malu kungakonzedwe bwino. Poyerekeza ndi njira zina zochotsera golide, cyanide ikhoza kukhala yotsika mtengo nthawi zina, makamaka poganizira kuchuluka kwa miyala yochepa yomwe ingakonzedwe pogwiritsa ntchito njira iyi.

Kuyenerera kwa ores otsika

1. Kuchotsa ndalama kuchokera ku miyala yamtengo wapatali: Kuchotsa mchere wa sodium cyanide mumtsuko wa miyala ndi koyenera kwambiri pochiza miyala yamtengo wapatali ya golide, makamaka yomwe ili ndi magiredi kuyambira 0.5 - 3g/t. Izi zakulitsa kwambiri kuchuluka kwa golide wopindulitsa pazachuma. M'mbuyomu, miyala yambiri yamtengo wapatali inkaonedwa kuti ndi yosafunika kukumba. Komabe, chifukwa cha kupita patsogolo kwa ukadaulo wochotsa miyala yamtengo wapatali, miyala iyi tsopano ingagwiritsidwe ntchito bwino. Mwachitsanzo, m'madera ena komwe miyala yamtengo wapatali ya golide ndi yochepa, kuchotsa golide kuchokera ku miyala yamtengo wapatali kudzera mumtsuko wa miyala kwakhala gwero lalikulu la kupanga golide.

2. Kugwiritsa ntchito zinthu zomwe sizinagwiritsidwe ntchito kale: Kumalola kugwiritsa ntchito mitundu yosiyanasiyana ya zinthu zomwe sizinagwiritsidwe ntchito kale, monga zinyalala za m'migodi, kuphatikizapo zinyalala zochokera ku ntchito zakale za m'migodi ndi miyala yotsika yomwe inasiyidwa panthawi ya ntchito ya migodi. Pokonza zinthuzi, sikuti golide wowonjezera ukhoza kupezedwanso kokha, komanso kumathandiza kuchepetsa kuwonongeka kwa chilengedwe komwe kumakhudzana ndi kusunga zinyalala zambiri.

Njira yosavuta

1. Kusavuta kugwiritsa ntchito: Njira yochotsera miyala mumtsuko imakhala yosavuta kugwiritsa ntchito. Mukamaliza kuyika miyala mumtsuko pa bolodi lokonzedwa bwino, ntchito yaikulu imaphatikizapo kupopera mankhwala a cyanide nthawi zonse pa mumtsukowo. Njirayi siifuna antchito aluso kwambiri pa ntchito za tsiku ndi tsiku. Ogwira ntchito amatha kuphunzitsidwa mwachangu kuti agwire ntchito monga kupopera mankhwala, kuyang'anira kuchuluka kwa madzi omwe atuluka, komanso kusonkhanitsa zitsanzo. Kusavuta kumeneku kumathandizanso kuchepetsa ndalama zogwirira ntchito zokhudzana ndi maphunziro ndi kulemba anthu ntchito akatswiri kwambiri.

2. Njira zochepa zokonzera: Poyerekeza ndi njira zovuta zochotsera golide, kuchotsa golide m'mizere kuli ndi njira zochepa zokonzera. Palibe chifukwa chopangira njira zambiri zolekanitsira mchere monga kuyandama kwa thovu, komwe kumaphatikizapo njira zingapo zowonjezerera zinthu zosiyanasiyana kuti zilekanitse mchere wokhala ndi golide ndi mchere wa gangue. Pochotsa golide m'mizere, njira ya cyanide imakhudza mwachindunji miyala yomwe ili mumizere, ndikusungunula golide ndi siliva, zomwe zimapangitsa kuti ntchito yonse yochotsera isakhale yovuta.

Kupita patsogolo kwaukadaulo kukulitsa luso

1. Njira zabwino zolumikizirana: Kupanga njira zabwino zolumikizirana kwawonjezera kwambiri mphamvu ya Sodium cyanide heap leaching . Kwa miyala yomwe ili ndi dothi lochepa kapena dongo lochuluka, kuphatikizana kungagwiritsidwe ntchito kukonza kuyenda kwa cyanide solution kudzera mu ore mumzere. Mwa kuwonjezera zomangira monga lime kapena simenti ya Portland ku ore kenako kunyowetsa ndikusakaniza mosakaniza, kupangidwa kwa njira zolumikizirana solution kumalimbikitsidwa. Izi zimapangitsa kuti kukhudzana bwino pakati pa cyanide solution ndi minerals zokhala ndi golide kukhale kothandiza, zomwe zimapangitsa kuti golide apezekenso bwino.

2. Kugwiritsa ntchito zowonjezera kuti ziwonjezere kuchotsedwa kwa chitsulo: Kuwonjezera zowonjezera zina kungathandize kwambiri njira yochotsera chitsulo. Mwachitsanzo, kugwiritsa ntchito zinthu zotulutsa mpweya monga mpweya woyera kapena calcium peroxide kungawonjezere mphamvu ya okosijeni ya yankho lochotsera chitsulo, ndikuwonjezera kusungunuka kwa golide. Kuphatikiza apo, zinthu zogwira ntchito pamwamba zitha kuwonjezeredwa kuti ziwongolere kunyowa kwa tinthu ta mkuwa ndi yankho la cyanide, ndikuwonjezera mphamvu ya leaching yonse. Kupita patsogolo kwaukadaulo kumeneku kwapangitsa kuti leaching ya Sodium Cyanide ikhale yothandiza kwambiri komanso yothandiza pochotsa golide kuchokera ku mitundu yosiyanasiyana ya miyala.
