E unuhi ana i ke gula mai loko mai o ka Oxidized Gold Ore

Ma ke ʻano, ʻaʻole hana ke gula me ka oxygen e hana i nā oxides e like me ka hao a i ʻole ke keleawe. Inā kanu ʻia i loko o nā lua kupapaʻu, ke one, a i ʻole ka hoʻomaha ʻana ma ke kai no nā kaukani makahiki, e hoʻomau mau ana nā hua gula, nā kīʻaha, a me nā kaola.

No laila, inā ʻaʻole i oxidize ke gula, he aha ke ʻano o ka oxidized gold ore?

Ka hoʻomaopopo ʻana i nā Oxidized Gold Ores

ʻO ka ʻai gula oxidized e pili ana i ke gula - lawe ʻia i ka ʻaila i hoʻokumu ʻia ma o nā kaʻina hana hoʻokahe kūlohelohe, ma mua o nā oxides gula.

Loaʻa i kēlā mau ores ke gula me nā oxides o nā metala e like me ka hao, ke keleawe, a me ka manganese. ʻO ka limonite a me ka pyrite nā minerala nui, me nā sulfides liʻiliʻi a ʻaʻohe paha, akā aia lākou i nā mineral lua paʻa e like me ke gula - lawe i ka hao hydroxides a i ʻole hydrated iron oxides, me kekahi quartz.

Hoʻololi ka ʻili o ka ʻili i nā minela sulfide mua i oxides a me hydroxides, me ke gula hiki ke hoʻokomo ʻia i loko o ka hematite, goethite, a i ʻole limonite.

He melemele a ʻeleʻele ke ʻano o ka ʻohe gula oxidized a ʻaʻohe kino. He mea waiwai nui ia no ka hana gula.

Pehea e unuhi ai i ke gula mai ka Oxidized Gold Ore?

I loko o ka ʻai gula oxidized, ʻo ka hapa nui o ke gula aia i loko o nā minerala gangue nui a me nā māwae o nā ʻokiki metala. He ʻokoʻa ka nui o ka ʻāpana gula, a he maʻalahi ke ʻano o ka mineral.

Ma mua o ka hoʻomaka ʻana i ka ʻohi ʻana a me ka wili ʻana, ʻo ka mālama mua ʻana i ka ʻai gula me kahi pale trommel kahi hana koʻikoʻi no ka hoʻomaikaʻi ʻana i ka pono pono, ʻoi aku hoʻi no nā ores gula oxidized i loko o ka pālolo.

Ma hope iho, hiki ke hana ʻia ka unuhi ʻana o ke gula me ka hoʻohana ʻana i nā ʻano hana e like me ka hoʻokaʻawale ʻana o ka umekaumaha , ka cyanidation , a i ʻole ka heap leaching.

KaʻAnuʻu Hana 1: Ore Crushing

Hoʻemi ka ʻohi ʻana i ka nui o ka ʻai gula oxidized a hana maʻamau me ka hoʻohana ʻana i kahi kaʻina maloʻo me ʻelua a ʻekolu mau ʻanuʻu ʻoki ʻana: mua, lua, a me ke kula kiʻekiʻe.

Ma hope o ka ʻoki ʻana, hoʻohana ʻia kahi pale vibrating e hoʻokaʻawale i ka ʻai gula oxidized. Ke hele nei nā ʻāpana liʻiliʻi ma nā puka aniani aʻo nā ʻāpana nui e waiho ana ma ka ʻili o ka pale a hoʻihoʻi ʻia no ka ʻohi hou ʻana.

KaʻAnuʻu 2: Ore Grinding

Hoʻokuʻu ʻo Grinding i ke gula mai nā minerala gangue i loko o ka ʻai gula oxidized, e hana ana i nā kūlana kūpono no ka loaʻa ʻana o ka pōmaikaʻi. ʻO nā lako wili maʻamau e pili ana i nā wili pōleʻa a me nā wili pā pulu.

KaʻAnuʻu Hana 3: ʻOre Beneficiation

He hana paʻakikī a koʻikoʻi ka loaʻa ʻana o ka ʻai gula oxidized. Hiki ke kohoʻia nā kaʻina hana unuhi likeʻole e like me keʻano o kaʻaila a me keʻano o ke gula. Eia kekahi mau ʻano hoʻomaikaʻi maʻamau:

1. Hoʻokaʻawale Gravity

ʻO ka hoʻokaʻawale ʻana i ka ʻumekaumaha he ʻano hana kino e hoʻohana ana i ka ʻokoʻa o ka umekaumaha kikoʻī ma waena o nā ʻeleʻele gula a me nā minerala gangue no ka hoʻokaʻawale ʻana.

Hoʻohana maʻamau ʻia nā mea hana hoʻokaʻawale gula oxidized gravity separation e pili ana i ka papa haʻalulu, spiral chute, jig, etc.

2. ʻO ka Cyanidation

ʻO ke ʻano cyanidation ka hana kemika i hoʻohana nui ʻia no ka ʻohi gula. He kūpono ia no ka eli liʻiliʻi a me waena o ka ʻeli ʻana o nā ʻaila gula oxidized, ʻoi aku ka nui o nā mea me ka nui o nā ʻāpana maikaʻi a me ka pae kiʻekiʻe.

Ma hope o ka wili ʻana, ua hui pū ʻia ka ʻai gula i hoʻoheheʻe ʻia me ka hopena cyanide , a ua hoʻoheheʻe ʻia ke gula i loko o ka wai ma o ka hopena leaching, a laila hoʻihoʻi ʻia ke gula ma o ka adsorption carbon i hoʻāla ʻia a i ʻole ka zinc precipitation.

Hāʻawi ʻo Cyanidation i nā uku hoʻihoʻi gula kiʻekiʻe a me ka hoʻohana ākea akā pili i nā hana paʻakikī a me nā kumukūʻai kiʻekiʻe ma muli o ka pono e mālama i ka ʻōpala cyanide.

3. Heap Leaching

He kūpono ka leaching puʻupuʻu no nā ʻāpana haʻahaʻa a i ʻole nā ​​ʻāpana nui o ka ʻaila gula oxidized, pinepine me ka ʻole o ka wili mua ʻana.

Ma hope o ka ʻoki ʻia ʻana, hoʻopaʻa ʻia ka ʻai gula ma luna o kahi pahu leaching puʻu hōʻoia ʻole, e hana ana i puʻu oka. Hoʻopili ʻia ka ʻaila cyanide ma luna o ka puʻu e hoʻoheheʻe i ke gula, a laila e hoʻihoʻi ʻia mai ka wai leach.

ʻO kēia kaʻina hana he haʻahaʻa kumu kūʻai kālā, hana maʻalahi, hiki ke hoʻololi i ka laulā, a he kūpono no ka ʻohi nui ʻana o nā ores gula haʻahaʻa. Eia nō naʻe, pono ia i ka nui o nā ʻāpana oka, no ka mea, hiki i nā ʻāpana maikaʻi loa ke hoʻopilikia i ka pono leaching.

ʻO kēia nā ʻano kumu nui ʻekolu no ka hana ʻana i nā mea gula oxidized. No ka hapa oxidized ores, gravity separation a me ka cyanidation ua hui pinepine. I loko o ka piha oxidized ores, coarse gula ka hapanui loaa me ka umekaumaha kaawale, oiai na mea gula maikai e malamaia me ka agitation cyanidation, a me one - nui particles ua hana me ka percolation cyanidation.

Panina

ʻO ka hana ʻana o ka ʻai gula oxidized e pili ana i ke ʻano o ka oka a me ke ʻano o ke gula. Ma ke koho ʻana i nā ʻano hana pōmaikaʻi kūpono a me ka hoʻomaikaʻi ʻana i nā kaʻina hana kuʻi, wili, a me ka hoʻokaʻawale ʻana, hiki ke hoʻonui ʻia nā uku hoʻihoʻi gula a hoʻomaikaʻi ʻia nā pono waiwai.

Shanxi United Chemical hua kiʻekiʻe ʻO Sodium cyanide ma o ka ʻenehana holomua a me nā lako. No nā nīnau loea e pili ana i ka cyanidation oka gula, heap leaching, etc., hiki iā ʻoe ke nīnau iā mākou i kēlā me kēia manawa. Kōkua mākou i nā mea kūʻai e hoʻokō i ka hoʻihoʻi gula maikaʻi a paʻa.
