He aha nā mea hoʻohana o ka flotation

He kaʻina hana ka hoʻohua ʻana i nā mea maka no ka hoʻoheheʻe ʻana i ka metala a me ka ʻoihana kemika, a ua lilo ka froth flotation i mea waiwai nui loa. Aneane hiki ke hoʻokaʻawale ʻia nā kumuwaiwai mineral me ka hoʻohana ʻana i ka flotation.

I kēia manawa, hoʻohana nui ʻia ka flotation i ka pōmaikaʻi o nā metala ferrous-ma mua o ka hao a me ka manganese-e like me ka hematite, smithsonite, a me ilmenite; nā metala makamae e like me ke gula a me ke kālā; nā metala non-ferrous e like me ke keleawe, ke kēpau, zinc, cobalt, nickel, molybdenum, a me ka antimony, me nā mineral sulfide e like me galena, sphalerite, chalcopyrite, bornite, molybdenite, a me ka pentlandite, a me nā mineral oxide e like me malachite, cerussite, hemimorphite, cassiterite, a me wolframite. Hoʻohana ʻia ia no nā mineral paʻakai non-metallic e like me ka fluorite, apatite, a me ka barite, soluble paʻakai mineral e like me ka potash a me ka paʻakai pōhaku, a me nā minela non-metallic a me nā mineral silicate e like me ka lanahu, graphite, sulfur, daimana, quartz, mica, feldspar, beryl, a me spodumene.

Ua hōʻiliʻili ʻo Flotation i ka ʻike nui ma ke kahua o ka pōmaikaʻi, me nā holomua ʻenehana mau. ʻO nā minerala i manaʻo ʻia ma mua ʻaʻohe waiwai ʻoihana ma muli o ko lākou papa haʻahaʻa a paʻakikī paha ke hoʻihoʻi ʻia nei (ma ke ʻano he kumu waiwai lua) ma o ka lele ʻana.

Ke māhuahua aʻe ka wīwī ʻana o nā minerala, me ka puʻunaue ʻia ʻana o nā minerala pono i loko o nā ores, ua ulu ka paʻakikī o ka hoʻokaʻawale ʻana. No ka hōʻemi ʻana i nā kumukūʻai hana, ua hoʻonohonoho nā ʻoihana e like me nā mea metallurgical a me nā kemika i nā kūlana kiʻekiʻe aʻe a me nā koi pololei no ka hana ʻana i nā mea maka-ʻo ia hoʻi nā huahana i hoʻokaʻawale ʻia.

Ma kekahi ʻaoʻao, pono e hoʻomaikaʻi i ka maikaʻi, a ma kekahi ʻē aʻe, ʻo ka paʻakikī o ka hoʻokaʻawale ʻana i nā minerala maikaʻi i ʻoi aku ka maikaʻi o ka flotation ma mua o nā ʻano hana ʻē aʻe, e hoʻokumu ana ʻo ia ka ʻenehana hoʻohana nui a hoʻohiki i kēia mau lā. I ka hoʻohana mua ʻia ʻana i nā minerala sulfide, ua hoʻonui mālie ʻia ka flotation e komo i nā mineral oxide a me nā mineral non-metallic. I kēia lā, ʻoi aku ka nui o ka nui o nā minerala i hoʻoili ʻia e ka flotation ma mua o kekahi mau piliona tons.

I nā makahiki i hala iho nei, ua hoʻonui ʻia ka noi ʻana o ka ʻenehana flotation ma mua o ka ʻenekini hana minerala i nā kula e like me ka pale ʻana i ke kaiapuni, metallurgy, papermaking, mahiʻai, kemika, meaʻai, mea waiwai, lāʻau lapaʻau, a me ka biology.

ʻO nā laʻana ka hoʻihoʻi hou ʻana o nā mea waiwai mai nā huahana waena ma pyrometallurgy, volatiles, a me ka slag; ka hoʻihoʻi hou ʻana o ka lele ʻana o nā koena leaching a me ka neʻe ʻana i ka wai i loko o ka hydrometallurgy; ka hoʻohana ʻana i ka flotation i loko o ka ʻoihana kemika no ka wehe ʻana i ka pepa i hana hou ʻia a me ka hoʻihoʻi ʻana i nā fiber mai ka wai ʻona ʻōpala; a me nā noi ʻenekinia kaiapuni maʻamau e like me ka ʻili ʻana i ka ʻaila koʻikoʻi nui mai nā sediment o ka muliwai, ka hoʻokaʻawale ʻana i nā mea haumia paʻa maikaʻi mai ka wai ʻino, a me ka wehe ʻana i nā colloids, bacteria, a me nā ʻano metala haumia.

Me ka hoʻomaikaʻi ʻana i nā kaʻina hana flotation a me nā ʻano hana, a me ka puka ʻana mai o nā mea hou a me nā mea hana flotation hou a maikaʻi loa, e ʻike ʻia ka flotation i nā noi ākea ma waena o nā ʻoihana a me nā kula. Eia nō naʻe, pono e hoʻomaopopo ʻia ʻo ka hoʻohana ʻana i ka flotation e pili ana i nā kumukūʻai hoʻoili kiʻekiʻe (e hoʻohālikelike ʻia me ka hoʻokaʻawale ʻana i ka magnetic a i ʻole ka gravity separation), nā koi koʻikoʻi no ka nui o ka meaʻai meaʻai, ka nui o nā mea hoʻohuli i ke kaʻina flotation e koi ana i ka pololei o ka hana kiʻekiʻe, a me nā pōʻino kaiapuni mai ka wai ʻino i loaʻa nā koena reagents.

E kelepona iā mākou i kēia manawa!
