Lead zinc ore saj

Qib ntawm cov hlau lead ore muab rho tawm los ntawm cov hlau lead-zinc mines feem ntau tsawg dua 3%, thiab cov ntsiab lus zinc tsawg dua 10%.Qib nruab nrab ntawm cov hlau lead thiab zinc hauv cov ore raw ntawm cov mines me thiab nruab nrab ntawm cov hlau lead-zinc yog li 2.7% thiab 6%, thaum cov mines loj loj tuaj yeem ncav cuag 3% thiab 10%.Cov muaj pes tsawg leeg ntawm cov concentrate feem ntau yog txhuas 40-75%, zinc 1-10%, sulfur 16-20%, thiab feem ntau muaj coexisting hlau xws li nyiaj, tooj liab, thiab bismuth;Kev tsim cov zinc concentrate feem ntau yog li 50% zinc, li 30% sulfur, 5-14% hlau, thiab tseem muaj me me ntawm cov hlau lead, cadmium, tooj liab, thiab cov hlau muaj txiaj ntsig.Ntawm cov kev lag luam hlau lead-zinc mining thiab xaiv cov lag luam, 53% muaj cov qhab nia qis dua lossis sib npaug li 5%, 39% muaj qib ntawm 5% -10%, thiab 8% muaj qib siab dua 10%.Feem ntau hais lus, tus nqi ntawm cov concentrate rau zinc loj mines nrog qib siab dua 10% yog hais txog 2000-2500 yuan / ton, thiab tus nqi ntawm zinc concentrate kuj nce raws li qib qis.

Nqe txheej txheem rau zinc concentrate

Tam sim no tsis muaj kev sib koom ua ke tus nqi rau zinc concentrates hauv Suav teb.Feem ntau cov smelters thiab mines siv SMM (Shanghai Nonferrous Metals Network) zinc nqi rho tawm cov nqi ua haujlwm los txiav txim cov nqi pauv ntawm zinc concentrates;Xwb, tus nqi pauv ntawm zinc concentrate tuaj yeem txiav txim siab los ntawm kev sib npaug ntawm SMM zinc nqi los ntawm qhov sib piv ruaj khov (xws li 70%).

Zinc concentrate yog suav rau hauv daim ntawv ntawm cov nqi ua haujlwm (TC / RC), yog li tus nqi ntawm zinc hlau thiab cov nqi ua haujlwm (TC / RC) yog qhov tseem ceeb cuam tshuam rau cov nyiaj tau los ntawm cov mines thiab smelters.TC / RC (Kev kho thiab kho cov nqi rau kev ua cov concentrates) yog hais txog kev ua thiab kho cov nqi ntawm kev hloov zinc concentrate rau hauv cov zinc refined.TC yog tus nqi ua haujlwm lossis nqi kho dua tshiab, thaum RC yog tus nqi kho dua tshiab.Tus nqi ua haujlwm (TC / RC) yog tus nqi them los ntawm cov miners thiab cov tub lag luam rau smelters los ua cov zinc concentrate rau hauv cov zinc refined.Tus nqi ua haujlwm TC / RC yog txiav txim los ntawm kev sib tham ntawm cov mines thiab smelters thaum pib ntawm txhua xyoo, thaum cov teb chaws Europe thiab North American feem ntau sib sau ua ke nyob rau lub Ob Hlis ntawm AZA lub rooj sib tham txhua xyoo ntawm American Zinc Association los txiav txim tus nqi ntawm TC / RC.Tus nqi ua haujlwm muaj cov nqi zinc hlau ruaj ruaj thiab tus nqi uas hloov pauv thiab nqis nrog cov nqi hlau hloov pauv.Kev hloov kho ntawm tus nqi ntab yog los xyuas kom meej tias cov kev hloov pauv ntawm cov nqi ua haujlwm yog synchronized nrog tus nqi ntawm zinc.Kev lag luam hauv tsev feem ntau yog siv cov txheej txheem ntawm kev rho tawm tus nqi tas li los ntawm tus nqi ntawm zinc los txiav txim siab tus nqi ntawm kev mloog zoo lossis sib tham los txiav txim siab tus nqi zinc ore.
