Copper ore beneficiation txoj kev thiab cov txheej txheem
Cov kev pab cuam thiab cov txheej txheem ntawm tooj liab ore yog suav tias yog rho tawm cov tooj liab los ntawm cov khoom qub, refining thiab ua nws.Cov hauv qab no feem ntau siv tooj liab ore beneficiation txoj kev thiab cov txheej txheem:
1. Kev sib cais ntxhib: Tom qab cov tooj liab ore yog crushed thiab hauv av, txoj kev siv lub cev yog siv rau kev sib cais ntxhib.Cov txheej txheem sib cais sib txawv muaj xws li kev sib cais ntawm lub ntiajteb txawj nqus, flotation, sib nqus sib cais, thiab lwm yam. Los ntawm kev sib txawv ntawm cov ntxhia ua tshuab thiab cov khoom siv thiab cov tshuaj ua cov ntxhia, cov khoom loj ntawm tooj liab ore thiab impurities nyob rau hauv cov ore raug sib cais.
2. Flotation: Thaum lub sij hawm flotation txheej txheem, qhov sib txawv ntawm affinity ntawm cov ore thiab cov npuas nyob rau hauv cov huab cua yog siv los txuas cov npuas rau cov tooj liab ore hais kom cais cov tooj liab ore thiab impurities.Feem ntau siv tshuaj nyob rau hauv cov txheej txheem flotation muaj xws li collectors, foaming agents thiab regulators.
3. Secondary beneficiation: Tom qab flotation, cov tooj liab concentrate tau tseem muaj ib tug npaum li cas ntawm impurities.Txhawm rau txhim kho qhov purity thiab qib ntawm tooj liab mloog zoo, yuav tsum tau txais txiaj ntsig thib ob.Cov kev pab cuam thib ob feem ntau suav nrog kev sib nqus sib nqus, sib cais sib nqus, leaching, thiab lwm yam. Los ntawm cov txheej txheem no, impurities nyob rau hauv tooj liab concentrate yog ntxiv tshem tawm thiab cov nqi rov qab thiab qib ntawm tooj liab ore zoo dua.
4. Refining thiab smelting: Copper concentrate yog tau los ntawm tooj liab ore tom qab cov ntxhia ua, uas yog ntxiv refined thiab smelted.Cov txheej txheem refining feem ntau suav nrog hluav taws refining thiab electrolytic refining.Pyro-refining smelts tooj liab mloog zoo ntawm qhov kub thiab txias kom tshem tawm cov impurities seem;electrolytic refining siv electrolysis kom yaj cov tooj liab hauv cov tooj liab mloog zoo thiab tso rau hauv cathode kom tau cov tooj liab ntshiab.
5. Kev ua thiab kev siv: Cov txheej txheem kev ua haujlwm xws li casting, dov, kos duab, thiab lwm yam., ua rau tooj liab rau hauv cov khoom siv tooj liab ntawm cov duab sib txawv thiab cov lus qhia tshwj xeeb.
