Mayskoye Gold nke m

Ebe a na-egwupụta ọla edo nke Mayskoye, nke dị na mpaghara Chukotka nke Russia, bụ ebe a na-emepụta ọla edo dị ịrịba ama nke nwere njirimara ọdịdị ala dị mgbagwoju anya. Ahụ ore bụ mpaghara breccia nwere mgbagwoju anya. Ihe mejupụtara ya bụ veins quartz bụ nke gbakọrọ n'etiti nkume a na-agbanwe agbanwe. veins quartz ndị a bụ ndị isi ọla edo, na nguzobe ha nwere njikọ chiri anya na ihe mgbagwoju anya tectonic na hydrothermal na mpaghara.

Enwere ụdị ọla abụọ bụ isi: nke isi ore, nke dị oke egwu refractory. Ọdịdị a na-emegharị emegharị na-abụkarị n'ihi mma - mgbasa ozi ọla edo n'ime mineral sulfide, dị ka pyrite na arsenopyrite. Ihe ndị a na-emepụta ihe na-ekpuchi ihe ndị ahụ ọla edo, na-eme ka ọ sie ike nke ukwuu iji ụzọ omenala wepụ ọla edo ahụ. Nke ore oxidized, n'aka nke ọzọ, bụ nke kachasị nke quartz mica. Tinyere quartz mica, enwere obere feldspar, kaolin, na sulfides. Usoro oxidation agbanweela mineralogy nke ore, nke na-emetụta ọla edo - usoro mmịpụta.

Maka nhazi nke ore oxidized, a na-eduzi ya na ụlọ ọrụ CIL (Carbon - in - Leach). Mgbe a na-ahazi ihe nlele ọla oxidized na mbụ n'ime ụlọ ọrụ CIL, ọnụego mgbake ọla edo adịchaghị ala. Nke a bụ n'ụzọ bụ isi sitere na mmetụta "preg - roasting" nke ihe ndị dị na ọla. Ihe ndị dị ndụ nwere njikọ siri ike maka ụlọ cyanide ọla edo, nke ọma "na-ezu ohi" ọla edo site na ngwọta leaching. Iji gbochie nsogbu a, a na-eme usoro nzọụkwụ abụọ. Nke mbụ, sere n'elu A na-eme ihe ndị nwere carbon. N'ime usoro ịkwọ ụgbọ mmiri a, a na-ahọrọ ndị na-anakọta na frothers nke ọma ma dozie ya ka ha kewaa ihe ndị na-ebu carbon na ndị ọzọ. Mgbe flotation gachara, a na-edobe ọdụ ọdụ ụgbọ mmiri ahụ.

N'ime osisi a, a na-etinye uche na oxidation, nke bụ nzọụkwụ dị oke mkpa iji mebie mineral sulfide ma hapụ ọla edo a kpuchiri ekpuchi. Mgbe oxidation gasịrị, cyanide tank leaching a na-eme. Ngwọta cyanide na-emeghachi omume na ọla edo, na-eme ọla edo soluble - cyanide complexes nke enwere ike ịhazi ya iji nwetaghachi ọla edo ahụ.

Obo ihe mkpofu ọla edo na-agbapụta

Na ọla edo Russia - ụlọ ọrụ na-egwuputa ihe, mkpofu mkpofu bụ isi iyi bara uru nke mgbake ọla edo nke abụọ. Obo mkpofu ndị a bụ ngwaahịa sitere n'ọrụ Ngwuputa na nhazi gara aga. Ha nwere nnukwu ọla edo, nke anatabeghị nke ọma n'oge usoro mmịpụta mbụ. Ọlaedo dị n'obo mkpofu na-adịkarị n'ụdị dị iche iche, gụnyere ọmarịcha - ụmụ irighiri ọla edo nwere ọka, ọla edo - mineral ndị na-ebu, na ọla edo a gbanyere n'elu mineral ndị ọzọ.

Nnyocha na-egosi na ọnụọgụ ọla edo na-esi n'obo mkpofu ndị a na-esi cyanidation percolation nwere ike iru 75% - 82%. Percolation cyanidation bụ usoro ebe a na-efesa ihe ngwọta cyanide na-agbaze ma ọ bụ tụba ya n'obo mkpofu. Ihe ngwọta cyanide na-agbaba site na mkpofu mkpofu, na-emeghachi omume na ọla edo ma na-akpụ ọla edo soluble - cyanide complexes. A na-anakọta ogige ndị a na ala nke mkpofu ahịhịa maka nhazi ọzọ.
