United Chemical, TuXingSun Mining, da Henan Lingbao Gold Mine Haɗaɗɗen Ƙaddamar da Ma'adinan Kyautar Cyanide

An yi amfani da sinadarin cire zinare mai kyau ga muhalli a masana'antu a Ma'adinan Zinare na Wenyu da ke Lingbao, Lardin Henan, musamman don haƙo abubuwa masu daraja kamar zinariya. Wannan aikin yana da sinadarin zinare na gram 9 a kowace tan da kuma sinadarin carbon mara kyau na 10.94%. Babban fa'idar wannan aikin shine bin ƙa'idodin muhalli, gami da amfani da sinadarin cire zinare mai kyau ga muhalli na Jinchan a madadin Sodium Cyanide . Wannan hanyar ba wai kawai tana tabbatar da ingantaccen haƙo zinare ba , har ma tana rage tasirin muhalli na tsarin sarrafa ma'adinai.

Idan niƙawar niƙa ta kai -0.074 mm, tare da abun ciki sama da 90%, yawan ɓangaren litattafan almara na 40%, adadin lemun tsami na 3 kg/t, lokacin kafin a yi maganin alkaline na awanni 2, adadin sinadarin zubar zinare mai kyau ga muhalli na Jinchan na 600 g/t, da kuma lokacin zubar da shi na awanni 24, ƙimar zubar da shi na zinariya zai iya kaiwa 95.60%. Idan aka kwatanta da zubar da shi na cyanide, ƙimar zubar da shi na zinariya zai iya kaiwa 1.4%, amfani da reagent yana raguwa da 200 g/t, kuma lokacin zubar da shi ya ragu da sama da awanni 12. Bugu da ƙari, wani bincike na guba na ragowar sinadarin zubar da shi na zinare mai kyau ga muhalli na Jinchan ya nuna cewa ƙimar gubar zubar da shi na cyanide, jan ƙarfe, gubar, zinc, da arsenic a cikin wutsiyoyin duk suna cikin iyakokin ƙasa kuma ana iya kawar da su kai tsaye ba tare da buƙatar tsarkakewa ba.

Babban abin da ke haifar da nasarar gwajin cikakken aikin cyanidation na lemun tsami shine amfani da ma'adinin zinare mai kyau na Jinchan. Wannan wakili na leaching an ƙera shi ne musamman don sauƙaƙe aikin leaching da shayarwa mai dorewa. Wakilin leaching na Jinchan yana amfani da leaching mai matakai hudu da tsarin sha na matakai biyar, yana tabbatar da cewa ko da kasancewar carbon inorganic, tasirin leaching na zinare ba ya tasiri. Wannan babban ci gaba ne ga aikin, yayin da yake nuna cewa hanyoyin da za su dace da yanayin muhalli na iya yin tasiri kamar hanyoyin gargajiya. Idan aka kwatanta da leaching cyanide, ƙimar leaching na iya haɓaka da 1.4%, ana rage yawan amfani da reagents da gram 200 a kowace ton, kuma an rage lokacin leaching sama da sa'o'i 12, yana haifar da sakamako mai kyau na leaching da fa'idodin tattalin arziƙi.

Sauya sinadarin sodium cyanide da sinadarin Jinchan mai hana muhalli ya nuna jajircewar ma'adinan ga kare muhalli . Sodium cyanide ya daɗe yana zama mizanin masana'antu na zubar da zinare, amma gubarsa na haifar da manyan haɗari ga muhalli da lafiyar ɗan adam. Sabanin haka, sinadarin Jinchan yana ba da madadin aminci da dorewa, yana tabbatar da cewa tsarin haƙar zinare ba ya kawo cikas ga lalacewar muhalli. Wannan sauyi zuwa ga ayyukan da suka dace da muhalli yana amfanar da yanayin muhalli na gida kuma yana kafa misali mai kyau ga masana'antar haƙar ma'adinai mai faɗi.

Aikin haƙar ma'adinai mai cike da lemun tsami a Ma'adinan Zinariya na Wenyu babban ci gaba ne ga kamfaninmu wajen kafa ma'adinan da ba shi da cyanide. Wannan aikin ya jaddada ayyukan kare muhalli, ta amfani da fasahohin zamani kamar na'urar cire zinare mai kyau ga muhalli ta Jinchan, wanda ke haifar da hanyoyin sarrafa ma'adinan zinare masu dorewa da alhaki. Ma'adinan Zinariya na Wenyu ya nuna cewa ana iya fitar da abubuwa masu daraja kamar zinare yadda ya kamata ba tare da cutar da muhalli ba, wanda hakan ke kafa sabuwar ma'auni ga masana'antar. Wannan aikin ya tabbatar da cewa ayyukan haƙar ma'adinai masu alhaki da kuma kula da muhalli na iya tafiya tare, wanda hakan ke share fagen samun makoma mai dorewa a fannin haƙar ma'adinai.
