Ka pomaikai gula

Hiki ke hoʻokaʻawale ʻia nā kumu waiwai gula refractory i ʻekolu mau ʻano nui:
ʻO ka ʻano mua he ʻano gula arsenic kiʻekiʻe, kalapona, a me ke ʻano sulfur.I kēia ʻano, ʻoi aku ka nui o ka arsenic ma mua o 3%, ʻo ka carbon content he 1-2%, a ʻo ka sulfur content he 5-6%.Ke hoʻohana nei i ke kaʻina hana ʻohi gula cyanide maʻamau, ʻo ka nui o ka leaching gula he 20-50% maʻamau, a pau ka nui o Na2CN.Ke hoʻonui ʻia e ka ʻenehana flotation, ʻoiai e hiki ke loaʻa i kahi pae kiʻekiʻe o ke gula concentrate, aia ka concentrate i nā pae kiʻekiʻe o nā mea ʻino e like me arsenic, carbon, a me antimony.He hopena ia i ka ʻanuʻu aʻe o ke kaʻina ʻohi gula.

ʻO ka lua o ka ʻano he gula i loko o nā ores kahi i wahī ʻia ai ke gula i nā minerala gangue a me nā haumia ʻino i loko o nā ʻāpana maikaʻi a me nā ʻano microscopic.Ma kēia ʻano, he liʻiliʻi ka mea metala sulfide, ma kahi o 1-2%, a hoʻokomo ʻia i loko o nā minerala gangue.ʻO nā ʻāpana gula maikaʻi i loko o nā kristal he 20-30%.Hoʻohana ʻia nā ʻano hana hoʻonui cyanide maʻamau no ka unuhi ʻana i ke gula, akā haʻahaʻa loa ka helu hoʻihoʻi gula.

ʻO ke kolu o ke ʻano he ʻano gula me ka pilina pili ma waena o ke gula, arsenic a me ka sulfur.ʻO kona hiʻohiʻona, ʻo ka arsenic a me ka sulfur ka mea lawe nui i nā minela gula o ke gula, a ʻo ka ʻike arsenic he medium.He haʻahaʻa haʻahaʻa ka papa kuhikuhi hoʻolele gula o kēia ʻano oka me ka hoʻohana ʻana i ke kaʻina ʻohi gula cyanide hoʻokahi.Inā hoʻonui ʻia ke gula ma ka lele ʻana, hiki ke loaʻa ke kiʻekiʻe o ka hoʻihoʻi hou ʻana, akā paʻakikī ke kūʻai aku no ka mea he nui ka arsenic.

ʻenehana mining

koho kemika

1. ʻO ka mineralization gula a me ka hoʻokaʻawale

ʻO nā ʻano hana hoʻopōmaikaʻi kemika o nā mines gula ka nui o ke ʻano wai mahana a me ke ʻano cyanide.ʻO ke ʻano o ka hui ʻana he mea kahiko a kūpono i ke gula hoʻokahi.Eia naʻe, he mea haumia a ua hoʻololi mālie ʻia e ka naʻauao.ʻElua mau ala cyanidation, hoʻoulu cyanidation a me percolation cyanidation.

2. Kemika a me ke gula koho lako

Hoʻohana ʻia ke ʻano kemika no ke koho ʻana i ka ʻai gula, ʻoi aku ka nui o ke ʻano o ka lewa.ʻO nā mea hana i hoʻohana ʻia, ʻo ia ka mea hoʻololi i ka pauka zinc, ka pahu hoʻoheheʻe leaching, a me nā mea ʻē aʻe.

ʻO ka pahu hoʻoulu leaching he mea hana ia no ka hoʻoulu ʻana i ka slurry.Ke emi ka nui o ka ʻeleʻele ma lalo o 200 mesh a ma lalo o 45% ka hopena o ka hopena, hiki ke hoʻokumu ʻia kahi hoʻokuʻu e hoʻonui i ka neʻe ʻana o ke gula i hoʻoheheʻe ʻia i loko o ka pahu adsorption a hoʻolōʻihi i ka manawa leaching.
