Mchitidwe waukadaulo wa Flotation-leaching wa miyala yamkuwa yagolide ku Russia

Mu mgodi wina wa golide ku Russia, miyala ya golide imadziwika kwambiri ndi mkuwa wambiri. Pambuyo pakusintha kwaukadaulo, mgodiwo udakumana ndi zovuta zingapo zomwe zidalepheretsa kupanga bwino.

Zovuta Zoyamba mu Beneficiation and Metallurgy System

• Mtengo Wochepa Wobwezeretsa Golide: Pambuyo posintha, chiwongoladzanja chobwezeretsa golide chinatsika kufika pamlingo wosakwanira, kulephera kukwaniritsa zolinga zomwe zikuyembekezeka.

• Kugwiritsa ntchito kwambiri sodium cyanide: Kumwa kwa Sodium cyanide kukwera, kuonjezera ndalama zogwirira ntchito kwambiri.

• Kuchuluka kwa Copper Ions: Ma ion amkuwa amapangidwa mosalekeza m'dongosolo, zomwe zimapangitsa kuti pakhale kupangika kwachilendo mu njira za beneficiation ndi zitsulo.

Zowonjezereka Zomwe Zimatheka Pofufuza ndi Kuchita

Kukhathamiritsa kwa Copper Flotation

• Kuwonjezeka kwa Copper Concentrate Zokolola: Zokolola za mkuwa zidasinthidwa bwino kuchokera ku 0.25% mpaka 0.75%.

• Mitengo Yapamwamba Yochira: Mitengo yoyandama ya golidi ndi mkuwa pakubwezeredwa mu copper flotation yawona kuwonjezeka kwakukulu. Chiwongola dzanja chobweza golide chinakwera kuchoka pa 20% kufika pafupifupi 35%, ndipo chiwongola dzanja chamkuwa chinakwera kuchoka pa 34% kufika pafupifupi 52%.

• Limbikitsani mu Total Gold Recovery: Chiwopsezo chonse chobwezeretsa golide chakwera kuchoka pa 87% mpaka 89%, kuwonetsa kuchita bwino kwambiri.

Leaching Process Optimization

• Kuchepetsa Nthawi ya Leaching: Nthawi ya leaching idadulidwa kuchokera ku 85.48 h mpaka 56.61 h, ndikuwongolera kuzungulira kwa kupanga.

• Lower Sodium Cyanide Concentration: The Sodium Cyanide Kuchulukirachulukira kunatsika kuchoka pa 1000 mg/L kufika pafupifupi 600 mg/L.

• Kuchepetsa Kugwiritsa Ntchito Sodium Cyanide: Kumwa kwa sodium cyanide zatsika kuchoka pa 7.49 kg/t kufika pa 3.60 kg/t, zomwe zinachititsa kuti ndalama zichepe.

• Lower Copper Leaching Rate: Mlingo wa leaching wamkuwa unatsika kuchokera ku 27.18% mpaka 20.09%, zomwe zimapindulitsa pazochitika zonse.

Chithandizo cha Copper Ion Reduction

Hydrogen Peroxide Cyanide Kuwonongeka ndi Kuchotsa Mkuwa

Kutengera kafukufuku woyeserera pakuchotsa mkuwa ndi hydrogen peroxide cyanide chiwonongeko, popanga, njira yophatikizira idakhazikitsidwa. Sodium metabisulfite ndi hydrogen peroxide adagwiritsidwa ntchito limodzi pochiza matenda amtundu wa alkali. Njirayi imachepetsanso mkuwa wa ayoni mu cyanide yotulutsa ore kuchokera ku 330.47 mg / L mpaka 24.55 mg / L, kuchepetsa kwambiri ayoni amkuwa mu dongosolo.

Zotsatira za machitidwe kupanga izi zikusonyeza bwino kuti kwa mkuwa wonyamula miyala golide mu Russia, njira monga kuonjezera mlingo mkuwa flotation kuchira, optimizing zinthu leaching kudula sodium cyanide mowa, kuchititsa hydrogen peroxide cyanide chiwonongeko, ndi kuchotsa mkuwa pansi zinthu mkulu-zamchere akhoza kubweretsa zotsatira zabwino kupanga. Mlanduwu uli ndi chitsogozo chachikulu pakukhathamiritsa kwa njira zopezera phindu ndi zitsulo ndi machitidwe opangira zinthu zofanana ndi zamkuwa zagolide.
