He aha ka flotation beneficiation?

ʻO ka flotation, i ʻike ʻia hoʻi ʻo ka froth flotation, he ʻano hana mineral e hoʻokaʻawale i nā mineral waiwai mai nā mineral gangue ma ka interface gas-liquid-solid ma o ka hoʻohana ʻana i nā ʻokoʻa o nā waiwai o ka ʻili o nā mineral like ʻole. Ua kapa ʻia hoʻi ʻo ia he "interfacial separation." ʻO kēlā me kēia kaʻina hana e hoʻohana pololei a ʻaʻole pololei paha i nā interfaces phase e hoʻokaʻawale i nā ʻāpana mineral ma muli o nā ʻokoʻa o kā lākou mau waiwai interfacial ua kapa ʻia ʻo flotation.

Pili nā waiwai o ka ʻili mineral i nā ʻano kino a me ke kemika o nā ʻili ʻāpana mineral, e like me ka pulu ʻana o ka ʻili, nā waiwai uila o ka ʻili, nā ʻano o nā pilina kemika ma nā ʻātoma o ka ʻili, ka saturation, a me ka reactivity. Hōʻike nā ʻāpana mineral like ʻole i nā waiwai ʻili like ʻole, a ma ka hoʻohana ʻana i kēia mau ʻokoʻa me ke kōkua o nā interfaces phase, hiki ke hoʻokō ʻia ka hoʻokaʻawale ʻana o ka mineral a me ka hoʻonui ʻana. No laila, pili ke kaʻina hana flotation i ka launa pū ʻana o ke kinoea, ka wai, a me nā pae paʻa ma ka interface.

Hiki ke hoʻololi ʻia nā ʻano o ka ʻili mineral ma o ke komo ʻana o ka hana hana e hoʻonui i nā ʻokoʻa ma waena o nā mineral waiwai nui a me nā mineral gangue, a laila e maʻalahi ai ko lākou hoʻokaʻawale ʻana. I ka flotation, hoʻohana pinepine ʻia nā reagents flotation e hoʻololi i nā ʻano o ka ʻili mineral, hoʻonui i nā ʻokoʻa ma waena o nā mineral, a hoʻonui a hoʻemi paha i ka hydrophobicity o nā ʻili mineral. ʻAe kēia i ka hoʻoponopono a me ka kaohi ʻana i ke ʻano o ka flotation mineral e hoʻokō i nā hopena hoʻokaʻawale maikaʻi aʻe. No laila, pili pono ka hoʻohana ʻana a me ka hoʻomohala ʻana o ka ʻenehana flotation i ka hoʻohana ʻana i nā reagents flotation.

ʻAʻole e like me nā palena kino e like me ka nui a me ka hiki ke hoʻololi ʻia e ka magnetic susceptibility, hiki ke hoʻololi maʻalahi ʻia nā waiwai o ka ʻili o nā ʻāpana mineral ma o ke komo ʻana o ke kanaka e hana i nā ʻokoʻa e hoʻokō ai i nā koi hoʻokaʻawale. ʻO ka hopena, ua hoʻohana nui ʻia ka flotation i ka hoʻokaʻawale ʻana o nā mineral a ua kapa pinepine ʻia ʻo ia ke "ʻano hana hana mineral honua." He kūpono loa ia a hoʻohana nui ʻia no ka hoʻokaʻawale ʻana i nā ʻāpana maikaʻi a me nā ultra-fine, e lilo ia i hoʻokahi o nā ʻano hana versatile a maikaʻi loa i ka hana ʻana i nā mineral.
