Na Kona Oka Copper Concentrates

ʻO ka Copper Concentrates, Malachite a me Ore mākou e kūʻai ai:

Kūʻai keleawe

ʻOhe Ore

Copper Concentrate ʻAmelika Hema

Hoʻopaʻa ʻia ʻo Copper Ore

ʻO ka hapa nui o nā mea keleawe he hapa liʻiliʻi wale nō o ke keleawe. ʻO ke koena o ka ʻaila he gangue ʻaʻohe waiwai kūʻai. Loaʻa i ka Gangue mai ka ʻeli keleawe ʻana i nā mineral silicate a me nā oxides. I kekahi mau hihia, ua hoʻihoʻi ʻia kēia mau huelo ma muli o ka hoʻomaikaʻi ʻana o ka ʻenehana no ka hoʻihoʻi ʻana i ke keleawe. Aia ma lalo o 21% keleawe ka helu awelika o nā ʻohe keleawe ma ka 0.6st century, me ka hapa o nā minela ʻeleʻele waiwai (me ke keleawe) ma lalo o 2% o ka nui o ka nui o ka pōhaku oka. ʻO kahi pahuhopu nui i ka hoʻomaʻamaʻa metallurgical o kēlā me kēia oka, ʻo ia ka hoʻokaʻawale ʻana o nā minerala mai nā mineral gangue i loko o ka pōhaku.

ʻO ka pae mua o kēlā me kēia kaʻina hana i loko o kahi kaapuni lapaʻau metallurgical ʻo ia ka wili pololei a i ʻole ka hoʻohui ʻana, kahi i ʻoki ʻia ai ka pōhaku e hana i nā ʻāpana liʻiliʻi (<100 μm) i loko o nā ʻāpana mineral pākahi. Hoʻokaʻawale ʻia kēia mau ʻāpana no ka wehe ʻana i nā gangue (nā koena o nā pōhaku), ma hope o ke kaʻina hana o ka hoʻokuʻu kino ʻana i nā minerala mai ka pōhaku. ʻO ke kaʻina hana o ka hoʻokuʻu ʻana i nā ores keleawe e pili ana inā he oxide a i ʻole sulfide ores.
ʻO nā ʻanuʻu aʻe e pili ana i ke ʻano o ka oka i loko o ke keleawe a me ka mea e unuhi ʻia. No ka oxide ores, hoʻohana mau ʻia kahi kaʻina hana hoʻokuʻu hydrometallurgical, e hoʻohana ana i ke ʻano soluble o nā minela oka i mea e pono ai ka mea kanu lapaʻau metallurgical. No nā ʻaila sulfide, ʻelua (supergene) a me ka mua (hypogene), hoʻohana ʻia ka froth flotation no ka hoʻokaʻawale kino ʻana i ka ʻohe mai ka gangue. No ke keleawe maoli maoli e lawe ana i nā kino ʻoʻa a i ʻole nā ​​ʻāpana o nā kino oka i waiwai i ke keleawe maoli supergene, hiki ke hoʻihoʻi ʻia kēia mineral me kahi kaapuni ʻumekaumaha maʻalahi.
