Lead zinc ore kuravira

Chiyero chematombo emutobvu anotorwa kubva mumigodhi yelead-zinc kazhinji kacho kari pasi pe3%, uye zinc iri pasi pegumi muzana.Avhareji yegiredhi remutobvu uye zinc musimbi mbishi yemigodhi yelead-zinc midiki nepakati ingangoita 2.7% ne6%, ukuwo migodhi mikuru yakapfuma inogona kusvika 3% ne10%.Kuumbwa kweiyo concentrate kunowanzo tungamira 40-75%, zingi 1-10%, sarufa 16-20%, uye kazhinji ine simbi dziripo sesirivha, mhangura, uye bismuth;Kuumbwa kwe zinc concentrate kunowanzo kuita 50% zinc, ingangoita 30% sarufa, 5-14% iron, uye zvakare ine mashoma mashoma emutobvu, cadmium, mhangura, uye simbi dzinokosha.Pakati pemabhizimusi emugodhi wemugodhi wezinc nekusarudza, 53% vane giredhi rakazara repasi kana kuenzana ne5%, 39% vane giredhi re5% -10%, uye 8% vane giredhi rakakura kupfuura gumi%.Kazhinji, mari yekuisa pfungwa pamigodhi mihombe yezinki ine giredhi rakakura kupfuura 10% ingangoita 2000-2500 yuan/ton, uye mutengo wezinc concentrate unowedzerawo sezvo giredhi richidzikira.

Mitengo nzira ye zinc concentrate

Parizvino hapana nzira yakabatana yemitengo yezinc inotarisa muChina.Zvizhinji zvekunyungudusa nemigodhi zvinoshandisa SMM (Shanghai Nonferrous Metals Network) mitengo yezinc inobvisa mari yekugadzira kuti ione mutengo wekutengesa we zinc concentrates;Neimwe nzira, mutengo wekutengesa we zinc concentrate unogona kutariswa nekuwanza mutengo weSMM zinc nereshiyo yakatarwa (semuenzaniso 70%).

Zinc concentrate inoverengwa nenzira yekubhadhara mari (TC / RC), saka mutengo we zinc simbi uye mari yekugadzira (TC / RC) ndiyo inonyanya kukanganisa mari yemigodhi uye smelters.TC/RC (Kurapwa nekunatsa machaji ekugadzirisa concentrates) inoreva magadzirirwo uye kukwenenzvera mutengo wekushandura zinc concentrate kuita zinc yakanatswa.TC ndiyo muripo wekugadzirisa kana muripo wekunatsa, nepo RC iri muripo wekunatsa.Muripo wekugadzira (TC/RC) muripo unobhadharwa nevacheri vemigodhi nevatengesi kune vanonyungudutsa kugadzira zinc concentrate kuita zinc yakanatswa.Mari yekugadzira TC/RC inotarwa nenhaurirano pakati pemigodhi nevanonyungudutsa pakutanga kwegore rimwe nerimwe, nepo nyika dzeEurope neNorth America dzinowanzoungana muna Kukadzi pamusangano wepagore weAZA weAmerican Zinc Association kuti uone mutengo weTC/RC.Mari yekugadzira ine yakagadziriswa zinc simbi base mutengo uye kukosha kunochinja-chinja kumusoro nekudzika nekuchinja kwemitengo yesimbi.Iko kugadziridzwa kweiyo inoyangarara kukosha ndeyekuona kuti shanduko mumari yekugadzira inowiriraniswa nemutengo we zinc.Musika wepamusha unonyanya kushandisa nzira yekubvisa kukosha kwakatarwa kubva pamutengo we zinc kuona mutengo we concentrate kana kutaurirana kuti uone mutengo we zinc ore.
