United Chemical, TuXingSun Mining, a me Henan Lingbao Gold Mine Hoʻokumu i kahi lua me Cyanide-Free.

Ua hoʻohana ʻia ka ʻenehana leaching gula maikaʻi ʻo Jinchan i ka ʻoihana ma Wenyu Gold Mine ma Lingbao, Henan Province, ʻoi loa no ka ʻohi ʻana i nā mea waiwai e like me ke gula. Loaʻa i kēia papahana kahi maʻi gula o 9 grams no ke tona a me ka kalapona ʻole maʻiʻo o 10.94%. ʻO ka pōmaikaʻi nui loa o kēia papahana ʻo ia ka hoʻokō ʻana i ke kaiapuni, me ka hoʻohana ʻana i ka ʻenehana leaching gula eco-friendly Jinchan ma ke ʻano he pani. ʻO ka sodium Cyanide. ʻAʻole kēia ʻano hana e hōʻoia i ka hana kiʻekiʻe ʻOhi gula akā e hoʻemi ana i ka hopena o ka hopena o ka hana ʻana i ka ʻai.

I ka wā e wili ai ka fineness -0.074 mm, me ka ʻike i ʻoi aku ma mua o 90%, kahi ʻāpana pulp o 40%, kahi lime dosage o 3 kg / t, kahi manawa hoʻomaʻamaʻa alkaline o 2 mau hola, kahi Jinchan eco-friendly gula leaching agent dosage o 600 g / t, a me ka manawa leaching o 24 mau hola, ke gula. Laki lele hiki i ka 95.60%. Hoʻohālikelike ʻia me ka leaching cyanide, piʻi ka nui o ka leaching e 1.4%, hoʻemi ka hoʻohana ʻana i ka reagent ma 200 g/ton, a ua pōkole ka manawa leaching ma mua o 12 mau hola. Eia kekahi, he leaching Ka nānā 'ana i ke kino ʻO ke koena o ka mea hoʻomaʻemaʻe gula kaiapuni ʻo Jinchan i hōʻike ʻia ka waiwai leaching toxicity no cyanide, copper, lead, zinc, a me arsenic i loko o nā huelo i loko o nā palena maʻamau o ka ʻāina a hiki ke hoʻokuʻu pololei ʻia me ka ʻole o ka detoxification.

ʻO ke kumu nui i ka hoʻāʻo kūleʻa o ka pāhana cyanidation piha-lime ʻo ia ka hoʻohana ʻana i ka ʻenehana leaching gula eco-friendly Jinchan. Hoʻolālā kūikawā ʻia kēia mea leaching no ka hoʻomaʻamaʻa ʻana i ke kaʻina hana leaching a me ka absorption. Hoʻohana ka ʻoihana leaching ʻo Jinchan i kahi kaʻina leaching ʻehā a me ʻelima mau kaʻina absorption, e hōʻoia ana ʻoiai me ka loaʻa ʻana o ke kalapona inorganic, ʻaʻole pili ka hopena leaching gula. He mea koʻikoʻi kēia no ka papahana, no ka mea, e hōʻike ana i ka hiki ke ʻoi aku ka maikaʻi o nā mea ʻokoʻa e like me nā hana kuʻuna. Ke hoʻohālikelike ʻia me ka leaching cyanide, hiki ke hoʻonui ʻia ka nui o ka leaching e 1.4%, hoʻemi ʻia ka hoʻohana ʻana o nā reagents e 200 grams no ka ton, a ua pōkole ka manawa leaching ma mua o 12 mau hola, e hopena i nā hopena leaching maikaʻi a me nā pōmaikaʻi waiwai nui.

ʻO ka hoʻololi ʻana o ka sodium cyanide me ka Jinchan eco-friendly gold leaching agent e hōʻike ana i ka hoʻokō ʻana o ka mine. Ka palekana o ka nohona. ʻO ka sodium cyanide ka lōʻihi o ka maʻamau o ka ʻoihana no ka leaching gula, akā ʻo kona ʻawaʻawa e hoʻopilikia nui i ke kaiapuni a me ke olakino kanaka. I ka hoʻokaʻawale ʻana, hāʻawi ka luna ʻo Jinchan i kahi ʻokoʻa palekana a ʻoi aku ka paʻa, e hōʻoiaʻiʻo ʻaʻole hiki mai ke kaʻina hana hoʻoiho gula ma ka hopena o ka hōʻino ʻana i ke kaiapuni. ʻO kēia neʻe ʻana i nā hana hoʻopōmaikaʻi kaiaola e hoʻopōmaikaʻi i ka ʻōnaehana kaiaola kūloko a hoʻokumu i kahi kumu hoʻohālike maikaʻi no ka ʻoihana mining ākea.

ʻO ka papahana cyanidation piha piha i ka Wenyu Gold Mine he mea nui ia no kā mākou hui i ka hoʻokumu ʻana i kahi mine cyanide-free. Hoʻoikaika kēia papahana i nā hana hoʻomalu kaiapuni, me ka hoʻohana ʻana i nā ʻenehana hou e like me ka Jinchan eco-friendly gold leaching agent, e alakaʻi ana i nā ʻano hana ʻai gula ʻoi aku ka paʻa a me ke kuleana. Hōʻike ka Wenyu Gold Mine i nā mea waiwai e like me ke gula hiki ke lawe maikaʻi ʻia me ka ʻole o ka hoʻopōʻino i ke kaiapuni, e hoʻonohonoho ana i kahi kūlana hou no ka ʻoihana. Hōʻoia kēia papahana ʻO ka mining kuleana Hiki i nā hana a me ka hoʻokele kaiapuni ke hele pū i ka lima, e hoʻopaʻa i ke ala no ka wā e hiki mai ana i ka hana ʻana.
