I ke kaʻina hana o ka hoʻokaʻawale magnetic o ka magnetite, ma muli o ka hoʻohuihui magnetic, he maʻalahi ke hana i nā "magnetic inclusions" a me nā "non-magnetic inclusions", kahi e hoʻopilikia nui ai i ka papa o nā concentrates. ʻO ka mīkini holoi a me ka hoʻohuihui electromagnetic piha piha i hoʻomohala kūʻokoʻa ʻia e Walt he hanauna hou o nā lako hoʻokaʻawale magnetic kahua magnetic nāwaliwali. Hoʻomaopopo piha ia i nā kahua ikaika piha e like me ka ikaika magnetic, gravity, buoyancy, centrifugal force, etc. I hui pū ʻia, hoʻoponopono ʻia nā palena hana e like me nā waiwai o ka ore, hiki ke hoʻemi pono i ka ʻike o nā haumia e like me ka silicon, phosphorus, a me ka sulfur i loko o nā ores magnetic, a loaʻa nā concentrates magnetite kiʻekiʻe a me nā huahana waena e like me nā concentrates i ke kaʻina hana hoʻokaʻawale magnetic, i kūpono mua ʻia. He kūpono ka concentrate hope loa no ka hana beneficiation o ka magnetite concentrator, kahi e wehe ai i kahi ala hou no ka concentrate hao o koʻu ʻāina e hoʻokō i ka hoʻolālā o ka "hoʻomaikaʻi a me ka hoʻemi ʻana i nā haumia".
Kumu hana
Hoʻokomo ʻia ka ʻaila i loko o ka ʻāpana waena a me luna o ka mīkini elutriation e ka hopper hānai ʻaila a me ka paipu hānai ʻaila, a holoi ʻia e ka wai holoi. Ma waena o nā wili ʻelua a i ka wā e pio ai ke wili, ʻoiai ua nāwaliwali loa ka ikaika magnetic i lalo, ua ʻoki ʻia a hoʻopuehu ʻia e ke kahe wai piʻi wikiwiki, i hui pū ʻia ai ka gangue hoʻokahi, ka slime ore a me nā meaola i hui pū ʻia, ʻoiai nā meaola i hui pū ʻia. Aia ke kāʻei holo i luna, a ma lalo o ka hana o ke kahe wai piʻi ikaika, piʻi aʻe ia i ka lihi kahe a hoʻokuʻu ʻia e lilo i mau tailings i haku ʻia me nā kino pili.
ʻO ke kumumanaʻo hana o ka mīkini koho panning electromagnetic
Hoʻopili ʻia nā minelala magnetic i loko o ka ore e ke kahua magnetic i hana ʻia e ke coil uila, a lilo nā ʻāpana ore magnetic magnetized i mau dipoles magnetic, a he nui nā dipoles magnetic e huki kekahi i kekahi e hana i nā kaulahao magnetic. Ke pio ka coil, ua hoʻopuehu piha ʻia ka loulou flux koke o ka mana pio e ka axial shearing ma lalo o ka hana o ka wili wikiwiki a me ke kahe wai e piʻi ana. Hana hou ʻia ke kaʻina hana ma luna nei i ka wā e hoʻoikaika ʻia ai ka coil aʻe a hoʻohemo ʻia. Hana ʻia kēia kaʻina hana no nā manawa he nui, i hiki ke koho ʻia ka mea magnetic i nā manawa he nui i loko o ka mīkini elutriation e loaʻa ai ka magnetite concentrate kiʻekiʻe, a i ka manawa like, ua hoʻemi ʻia ka nui o nā haumia e like me SiO2.
Ke kaʻina hana hoʻomalu o ka mīkini holoi
Hoʻohana ka mīkini elutriation i ka mana ʻelua-impulse, ʻo ia hoʻi, ʻo ka nui o ka overflow a me ka underflow concentration nā pahuhopu kaohi. Hoʻomalu ʻia ka nui o ka overflow concentration e ka nui o ka ikaika o ke kahua magnetic, a hoʻomalu ʻia ka underflow concentration e ka wehe ʻana o ka valve lalo. I loko o ka ʻōnaehana kaohi, ma ka hoʻonohonoho ʻana i nā waiwai pahuhopu o ka overflow concentration a me ka underflow concentration, hoʻohana ka ʻōnaehana kaohi i kahi algorithm kaohi akamai e kaohi i ka ikaika o ke kahua magnetic a me ka wehe ʻana o ka valve lalo e mālama i ka waiwai pahuhopu i loko o kahi pae hana.
Ke paʻa ʻole ka nui o ka hānai ʻana o ka ore, e hoʻoponopono koke ka ʻōnaehana hoʻomalu i ka valve lalo e like me ka loli o ka hoʻohuihui underflow i loko o ka mīkini elutriation, i ʻole e loli ka magnetic medium i loko o ka mīkini elutriation a mālama i kahi ʻano hoʻokaʻawale paʻa; Ke paʻa ʻole ka lako wai, hoʻoponopono ka ʻōnaehana hoʻomalu i ka ikaika o ke kahua magnetic e like me ka loli o ka hoʻohuihui overflow o ka mīkini holoi e hōʻoia i ka paʻa o ka index concentrate.
Hoʻohana ka mīkini panning a me ke koho electromagnetic aunoa i ke ʻano hoʻomalu hoʻonui PID-akomi holomua, ʻaʻole pono ka hana lima a hana mau i ke kūlana maikaʻi loa. Ke hoʻohana nei i ka ʻenehana Pūnaewele o nā Mea, hoʻouna ʻia nā palena hana i ka paepae ao mamao, a ua hoʻokumu ʻia nā faila uila no nā lako e hoʻokele i ke ola holoʻokoʻa; Hiki i nā loea hana mineral o kā mākou hui ke hoʻoponopono mamao i nā palena hana mineral o ka mīkini holoi ma o ka paepae nānā mamao e lawelawe maikaʻi i nā mea hoʻohana.
