United Chemical, TuXingSun Mining, na Henan Lingbao Gold Mine jikọ aka guzobe nke m na-enweghị Cyanide

A na-eji ihe na-eme ka ọla edo dị ọcha nke Jinchan mee ihe n'ụlọ ọrụ mmepụta ihe na Wenyu Gold Mine dị na Lingbao, Henan Province, karịsịa maka iwepụta ihe dị oké ọnụ ahịa dị ka ọlaedo. Ọrụ a nwere gram 9 kwa tọn na ọdịnaya carbon Inorganic nke 10.94%. Uru kachasị nke ọrụ a bụ na ọ na-agbaso gburugburu ebe obibi ya, gụnyere iji ihe na-eme ka ọla edo dị ọcha nke Jinchan dị ka ihe nnọchi anya Sodium Cyanide . Usoro a abụghị naanị na ọ na-eme ka mwepụta ọla edo dị irè nke ukwuu kamakwa ọ na-ebelata mmetụta gburugburu ebe obibi nke usoro nhazi ọla.

Mgbe nchacha dị -0.074 mm, nke ihe dị n'ime ya karịrị 90%, njupụta pulp nke 40%, ọgwụ lime nke 3 kg/t, oge tupu ọgwụgwọ alkaline nke awa 2, ọgwụ Jinchan nke na-anaghị emerụ gburugburu ebe obibi nke 600 g/t, na oge nchacha nke awa 24, ọnụego nchacha ọlaedo nwere ike iru 95.60%. Ma e jiri ya tụnyere nchacha cyanide, ọnụego nchacha ọlaedo nwere ike iru 1.4%, ojiji reagent na-ebelata site na 200 g/t, oge nchacha ahụ na-ebelatakwa ihe karịrị awa 12. Ọzọkwa, nyocha nke nchacha nke ihe fọdụrụ na-anaghị emerụ gburugburu ebe obibi nke Jinchan gosiri na uru nchacha maka cyanide, ọla kọpa, lead, zinc, na arsenic na ọdụ ndị ahụ dị n'ime oke ọkọlọtọ mba ma enwere ike iwepụ ya ozugbo na-enweghị mkpa maka nchacha.

Isi ihe dị na nnwale na-aga nke ọma nke ọrụ cyanidation zuru oke bụ iji Jinchan eco-friendly leaching ọla edo. Emebere ụlọ ọrụ leaching a ka ọ kwado usoro ịhịa ahụ na nnabata nke ọma. Onye na-ahụ maka leaching Jinchan na-arụ ọrụ leaching anọ na usoro nnabata nke ise, na-ahụ na ọbụlagodi ọnụnọ nke carbon inorganic, ọ naghị emetụta mmetụta leaching ọla edo. Nke a bụ ọganihu dị ịrịba ama maka ọrụ ahụ, dịka ọ na-egosi na ihe ndị ọzọ eco-eco-friendly nwere ike ịdị irè dị ka usoro omenala. E jiri ya tụnyere cyanide leaching, ọnụọgụ leaching nwere ike ịbawanye site na 1.4%, oriri nke reagents na-ebelata site na gram 200 kwa ton, na oge nkwụsịtụ na-ebelata ihe karịrị awa 12, na-ebute mmetụta dị mma na uru akụ na ụba.

Ndochi nke sodium cyanide na ihe na-eme ka ọla edo dị ọcha nke Jinchan dị mma maka gburugburu ebe obibi na-egosi nkwa nke ebe a na-egwupụta ihe na nchekwa gburugburu ebe obibi. Sodium cyanide abụrụla ọkọlọtọ ụlọ ọrụ maka ịkụ ọlaedo, mana nsí ya na-akpata nnukwu ihe egwu nye gburugburu ebe obibi na ahụike mmadụ. N'ụzọ dị iche, ihe na-eme ka Jinchan dị mma na nke na-adịgide adịgide, na-eme ka usoro mwepụ ọlaedo ghara ịkpata mmebi gburugburu ebe obibi.
