Lead-zinc mine, pehea e koho ai?

Ma waena o nā ʻano mineral he nui, ʻo ke lead-zinc ore kahi mea paʻakikī e koho.ʻO ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi o ka ʻaila lead-zinc ma mua o nā ores waiwai a ʻoi aku ka paʻakikī o nā mea pili.No laila, pehea e hoʻokaʻawale maikaʻi ai i ke alakaʻi a me ka zinc ores he mea koʻikoʻi hoʻi ia i ka ʻoihana hoʻoili mineral.I kēia manawa, ʻo ke poʻo a me ka zinc mineral i loaʻa no ka hoʻohana ʻana i ka ʻoihana ka nui o ka galena a me ka sphalerite, a me ka smithsonite, cerussite, a me nā mea ʻē aʻe. ʻOka zinc oxide, a hui pū ʻia ke kēpau-zinc.Ma lalo iho nei mākou e kālailai pono i ke kaʻina hana hoʻokaʻawale o ke kēpau-zinc ore e pili ana i ka degere oxidation o ke kēpau-zinc ore.

ʻO ke kaʻina hoʻokaʻawale ʻana o ke alakaʻi-zinc sulfide
Ma waena o ke kēpau-zinc sulfide ore a me ke lead-zinc oxide ore, ʻoi aku ka maʻalahi o ka hoʻokaʻawale ʻana.Loaʻa pinepine ʻia ka galena, sphalerite, pyrite, a me ka chalcopyrite ʻo Lead-zinc sulfide ore.ʻO nā mineral gangue nui ka calcite, quartz, dolomite, mica, chlorite, a me nā mea ʻē aʻe. No laila, e like me ka pilina i hoʻopili ʻia o nā minerala pono e like me ke alakaʻi a me ka zinc, hiki i ka pae wili ke koho i kahi kaʻina wili hoʻokahi a i ʻole ke kaʻina wili nui. .

Hoʻohana pinepine ʻia ke kaʻina hana wili hoʻokahi no ka hana ʻana i nā ores lead-zinc sulfide me ka nui o ka palaoa coarser a i ʻole nā ​​pilina symbiotic maʻalahi;

ʻO ke kaʻina hana wili he nui ke alakaʻi-zinc sulfide ores me nā pilina intercalation paʻakikī a i ʻole ka nui o nā ʻāpana.

No nā ores lead-zinc sulfide, hoʻohana pinepine ʻia ka huelo regrinding a i ʻole ka coarse concentrate regrinding, a ʻaʻole hoʻohana pinepine ʻia ke kaʻina hana hoʻoheheʻe ʻia.I ka hoʻokaʻawale ʻana, hoʻohana pinepine ʻia ke kaʻina flotation ke alakaʻi-zinc sulfide ore.ʻO nā kaʻina hana flotation i hoʻohana ʻia i kēia manawa, ʻo ia hoʻi: ke kaʻina flotation mua, kaʻina flotation hui ʻia, etc. i koho nui ʻia ma muli o ko lākou nui ʻokoʻa a me nā pilina pili.

Ma waena o lākou, ʻo ke kaʻina hana flotation like kekahi mau pono i ke kaʻina flotation o ke alakaʻi-zinc oka no ka mea e hui pū i ke kaʻina o ka flotation o nā ores paʻakikī e hoʻokaʻawale a me nā ores maʻalahi e hoʻokaʻawale a hoʻopau i nā kemika liʻiliʻi, ʻoi aku ka maʻalahi. -e hoʻokaʻawale i nā ores i loko o ka ʻeleʻele.Ke lana ʻelua ʻano minerala kepau a me ka zinc e lana a paʻakikī ke lana, ʻoi aku ka maikaʻi o ke kaʻina flotation.

Kaʻina hoʻokaʻawale o ka zinc oxide ore
ʻO ke kumu i ʻoi aku ka paʻakikī o ke koho ʻana ma mua o ka lead-zinc sulfide ore ma muli o kāna mau mea paʻakikī, nā ʻāpana pili paʻa ʻole, ka nui o nā mea i hoʻopili ʻia, a me ka floatability like o nā minerala lead-zinc oxide a me nā mineral gangue. a me ka mineral slime., ma muli o nā hopena ʻino o nā paʻakai hiki ke hoʻoheheʻe ʻia.

Ma waena o nā ores lead-zinc oxide, ʻo ka poʻe me ka waiwai ʻoihana e komo pū me ka cerusite (PbCO3), ke alakaʻi vitriol (PbSO4), smithsonite (ZnCO3), hemimorphite (Zn4 (H2O) [Si2O7] (OH)2), etc. I waena o lākou, cerusite , ke alakaʻi vitriol a me ka molybdenum lead ore he mea maʻalahi ke sulfide.Hiki ke hoʻohana ʻia nā mea sulfide e like me ka sodium sulfide, calcium sulfide a me ka sodium hydrosulfide no ka mālama sulfurization.Eia nō naʻe, pono ke alakaʻi vitriol i kahi manawa pili lōʻihi i ka wā o ka hana vulcanization.ʻO ka mea hana vulcanizing He ʻano nui nō hoʻi.Eia naʻe, paʻakikī ka arsenite, chromite, chromite, etc.E lilo ana ka nui o nā minela pono i ka wā o ka hoʻokaʻawale ʻana.No nā ores lead-zinc oxide, koho ʻia ke kaʻina hana flotation ma ke ʻano he kaʻina hoʻokaʻawale nui, a hana ʻia nā hana desliming ma mua o ka flotation e hoʻomaikaʻi i nā hōʻailona flotation a me ke ʻano o nā kemika.Ma ke ʻano o ke koho ʻana i nā mea hana, ʻo ka long-chain xanthate he mea hōʻiliʻili maʻamau a maikaʻi.Wahi a nā hopena hoʻokolohua like ʻole, hiki ke hoʻololi ʻia me Zhongoctyl xanthate a i ʻole No. 25 lāʻau ʻeleʻele.ʻO nā mea hōʻiliʻili ʻakika momona e like me ka ʻakika oleic a me ke kopa paraffin oxidized ʻaʻole maikaʻi ke koho ʻana a kūpono wale ia no nā ores kepau kiʻekiʻe me nā silicates ma ke ʻano he gangue nui.
