He aha nā noi o ka flotation

ʻO ka hoʻomaʻemaʻe ʻana i ka ʻaila he hana hana e hoʻomākaukau ai i nā mea maka no ka hoʻoheheʻe ʻana i ka metala a me ka ʻoihana kemika, a ua lilo ka flotation froth i ke ʻano hoʻomaʻemaʻe koʻikoʻi loa. Hiki ke hoʻokaʻawale ʻia nā kumuwaiwai mineral āpau me ka hoʻohana ʻana i ka flotation.

I kēia manawa, ua hoʻohana nui ʻia ka flotation i ka hoʻomaikaʻi ʻana i nā metala ferrous—ʻo ia hoʻi ka hao a me ka manganese—e like me ka hematite, smithsonite, a me ka ilmenite; nā metala makamae e like me ke gula a me ke kālā; nā metala non-ferrous e like me ke keleawe, ke kēpau, ka zinc, ka cobalt, ka nickel, ka molybdenum, a me ka antimony, me nā minelala sulfide e like me ka galena, sphalerite, chalcopyrite, bornite, molybdenite, a me ka pentlandite, a me nā minelala oxide e like me ka malachite, cerussite, hemimorphite, cassiterite, a me ka wolframite. Hoʻohana ʻia nō hoʻi ia no nā minelala paʻakai non-metallic e like me ka fluorite, apatite, a me ka barite, nā minelala paʻakai hiki ke hoʻoheheʻe ʻia e like me ka potash a me ka paʻakai pōhaku, a me nā minelala non-metallic a me nā minelala silicate e like me ke kalapona, graphite, sulfur, daimana, quartz, mica, feldspar, beryl, a me ka spodumene.

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

I ka lilo ʻana o nā kumuwaiwai mineral i mea wiwi, me nā mineral pono i hoʻolaha maikaʻi ʻia a paʻakikī hoʻi 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 a me nā koi pololei no ka hana ʻana i nā mea maka—ʻo ia hoʻi, nā huahana i hoʻokaʻawale ʻia.

Ma kekahi ʻaoʻao, aia kahi pono e hoʻomaikaʻi i ka maikaʻi, a ma kekahi ʻaoʻao, ʻo ka paʻakikī o ka hoʻokaʻawale ʻana i nā minelala maikaʻi i hoʻolilo i ka flotation i ʻoi aku ka maikaʻi ma mua o nā ʻano hana ʻē aʻe, e hoʻokumu ana iā ia ma ke ʻano he ʻenehana hoʻomaikaʻi i hoʻohana nui ʻia a hoʻohiki i kēia lā. I hoʻohana mua ʻia i nā minelala sulfide, ua hoʻonui mālie ʻia ka flotation e hoʻokomo i nā minelala oxide a me nā minelala ʻaʻole metala. I kēia lā, ʻoi aku ka nui o ka nui o nā minelala i hana ʻia e ka flotation ma mua o kekahi mau piliona tone.

I nā makahiki i hala iho nei, ua hoʻonui ʻia ka hoʻohana ʻana o ka ʻenehana flotation ma mua o ka ʻenekinia hana mineral i nā kahua e like me ka palekana o ke kaiapuni, ka metallurgy, ka hana pepa, ka mahiʻai, nā kemika, ka meaʻai, nā mea hana, nā lāʻau lapaʻau, a me ka biology.

ʻO nā hiʻohiʻona e pili ana i ka hoʻōla ʻana o ka flotation o nā ʻāpana waiwai mai nā huahana waena i ka pyrometallurgy, volatiles, a me ka slag; ka hoʻōla ʻana o ka flotation o nā koena leaching a me nā precipitates displacement i ka hydrometallurgy; ka hoʻohana ʻana o ka flotation i ka ʻoihana kemika no ka de-ink recycled paper a me ka hoʻōla ʻana i nā fibers mai ka pulp neoneo wai; a me nā noi ʻenekinia kaiapuni maʻamau e like me ka unuhi ʻana i ka ʻaila maka kaumaha mai nā sediments kahawai, ka hoʻokaʻawale ʻana i nā mea haumia paʻa maikaʻi mai ka wai hoʻoneoneo, a me ka wehe ʻana i nā colloids, bacteria, a me nā mea haumia metala trace.

Me nā hoʻomaikaʻi ʻana i nā kaʻina hana a me nā ʻano hana flotation, a me ka puka ʻana mai o nā reagents flotation hou a me nā lako hana kūpono loa, e ʻike ʻia ka flotation i nā noi ākea aʻe ma nā ʻoihana a me nā kahua. Eia nō naʻe, he mea kūpono ke hoʻomaopopo ʻana ʻo ka hoʻohana ʻana i ka flotation e pili ana i nā kumukūʻai hana kiʻekiʻe (hoʻohālikelike ʻia me ka hoʻokaʻawale magnetic a i ʻole ka umekaumaha), nā koi koʻikoʻi no ka nui o ka ʻāpana hānai, nā mea hoʻohuli he nui i ke kaʻina hana flotation e koi ana i ka pololei hana kiʻekiʻe, a me nā pōʻino kaiapuni mai ka wai hoʻoneoneo e loaʻa ana nā reagents koena.

E leka uila mai iā mākou i kēia manawa!
