Lead zinc ore ono

ʻO ka pae o ka ʻai kepau i lawe ʻia mai nā mines lead-zinc ma ke ʻano he emi ma mua o 3%, a ʻo ka ʻike zinc ma lalo o 10%.ʻO ka pae maʻamau o ke kēpau a me ka zinc i loko o ka ʻai maka o nā mines lead-zinc liʻiliʻi a ma kahi o 2.7% a me 6%, ʻoiai hiki i nā mines waiwai nui ke hiki i 3% a me 10%.ʻO ka hui ʻana o ka concentrate he alakaʻi maʻamau 40-75%, zinc 1-10%, sulfur 16-20%, a loaʻa pinepine nā metala e like me ke kālā, ke keleawe, a me ka bismuth;ʻO ka hoʻokumu ʻana o ka zinc concentrate ma kahi o 50% zinc, ma kahi o 30% sulfur, 5-14% hao, a loaʻa pū kekahi mau mea liʻiliʻi o ke kēpau, cadmium, keleawe, a me nā metala makamae.Ma waena o nā ʻoihana mining lead-zinc a me nā ʻoihana koho, ʻo 53% ka helu piha o ka liʻiliʻi a i ʻole like me 5%, 39% ka helu o 5% -10%, a ʻo 8% ka helu ʻoi aku ma mua o 10%.ʻO ka mea maʻamau, ʻo ke kumukūʻai o ka concentrate no nā mines zinc nui me ka helu ʻoi aku ka nui ma mua o 10% ma kahi o 2000-2500 yuan/ton, a piʻi pū ke kumukūʻai o ka zinc concentrate i ka emi ʻana o ka papa.

Ke ala kumu kūʻai no ka zinc concentrate

I kēia manawa, ʻaʻohe ala kumu kūʻai hoʻohui no ka zinc concentrates ma Kina.ʻO ka hapa nui o nā mea hoʻoheheʻe a me nā mines e hoʻohana ana i nā kumukūʻai zinc SMM (Shanghai Nonferrous Metals Network) me ka hoʻemi ʻana i nā uku hana e hoʻoholo ai i ke kumukūʻai kūʻai o nā concentrates zinc;ʻO kahi ʻē aʻe, hiki ke hoʻoholo ʻia ke kumu kūʻai o ka zinc concentrate ma o ka hoʻonui ʻana i ke kumukūʻai zinc SMM me kahi ratio paʻa (e laʻa me 70%).

Kuhi ʻia ka Zinc concentrate ma ke ʻano o nā uku hoʻoili (TC / RC), no laila ʻo ke kumukūʻai o ka metala zinc a me nā uku hana (TC / RC) nā kumu nui e pili ana i ka loaʻa kālā o nā mines a me nā mea hoʻoheheʻe.ʻO ka TC/RC (Ka uku hoʻomaʻamaʻa a me ka hoʻomaʻemaʻe ʻana no ka hana ʻana i nā concentrates) e pili ana i ka hana ʻana a me ka hoʻomaʻemaʻe ʻana i nā kumukūʻai no ka hoʻololi ʻana i ka zinc concentrate i ka zinc hoʻomaʻemaʻe.ʻO TC ka uku hana a hoʻomaʻemaʻe paha, ʻoiai ʻo RC ka uku hoʻomaʻemaʻe.ʻO ka uku hoʻoponopono (TC/RC) ke kumukūʻai i uku ʻia e nā miners a me nā mea kālepa i nā mea hoʻoheheʻe ʻia e hana i ka zinc concentrate i loko o ka zinc i hoʻomaʻemaʻe ʻia.Hoʻoholo ʻia ka uku hana TC/RC e nā kūkākūkā ma waena o nā mines a me nā mea hoʻoheheʻe ʻia i ka hoʻomaka ʻana o kēlā me kēia makahiki, ʻoiai ʻo nā ʻāina ʻEulopa a me ʻAmelika ʻĀkau e hōʻuluʻulu maʻamau i Pepeluali ma ka hālāwai makahiki AZA o ka American Zinc Association e hoʻoholo ai i ke kumukūʻai o TC/RC.ʻO ka uku hoʻoponopono he kumu kūʻai kumu kūʻai metala zinc paʻa a me kahi waiwai e loli ana i luna a i lalo me nā loli kumukūʻai metala.ʻO ka hoʻoponopono ʻana i ka waiwai lana e hōʻoia i ka hoʻololi ʻana i nā uku hoʻoili me ke kumukūʻai o ka zinc.Hoʻohana nui ka mākeke kūloko i ke ʻano o ka unuhi ʻana i kahi waiwai paʻa mai ke kumu kūʻai o ka zinc e hoʻoholo ai i ke kumukūʻai o ka concentrate a i ʻole ke kūkākūkā e hoʻoholo i ke kumukūʻai o ka zinc ore.
