(2) Molten pas dej ua ke smelting
Molten pas dej smelting suav nrog Teniente tooj liab smelting txheej txheem, Mitsubishi txheej txheem, Osmet txheej txheem, Vanyukov tooj liab smelting txheej txheem, Isa smelting txheej txheem, Noranda txheej txheem, saum-blown rotary rauv txheej txheem (TBRC), Baiyin tooj liab smelting txheej txheem, Shuikoushan tooj liab smelting txheej txheem thiab tshuab tshuab oxygen-enriched smelting txheej txheem. Molten pas dej ua ke smelting yog ntxiv nplua sulfide mloog mus rau yaj thaum tshuab cua los yog muaj oxygen mus rau hauv lub yaj, thiab nqa tawm intensive smelting nyob rau hauv ib tug hnyav stirred molten pas dej ua ke. Vim hais tias lub moj tej tawg presses npuas nyob rau hauv lub molten pas dej ua ke, thaum cov npuas nce los ntawm lub molten pas dej ua ke, lawv ua rau lub "melt kem" txav, yog li inputting ib tug loj npaum li cas ntawm lub zog rau hauv lub yaj. Nws cov hom hluav taws xob muaj xws li kab rov tav, ntsug, tig los yog tsau, thiab cov txheej txheem blasting muaj xws li sab tshuab, sab saum toj tshuab thiab hauv qab tshuab.
Molten pool smelting tau siv hauv kev lag luam txij li xyoo 1970s. Vim qhov zoo ntawm cov cua sov thiab huab cua hloov pauv thaum lub sij hawm molten pas dej ua ke smelting txheej txheem, cov txheej txheem metallurgical tuaj yeem txhim kho tau zoo, ua tiav lub hom phiaj ntawm kev txhim kho cov cuab yeej tsim khoom thiab txo kev siv hluav taws xob hauv cov txheej txheem smelting. Ntxiv mus, qhov yuav tsum tau ua rau cov nqi hluav taws xob tsis siab. Txhua hom concentrates, qhuav, ntub, loj hais, thiab hmoov yog siv tau. Lub qhov cub ntim me me, qhov kub poob yog me me, thiab kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig yog qhov zoo. Tshwj xeeb, cov pa luam yeeb tsawg tsawg dua li ntawm flash smelting.
Ausmelt txheej txheem: Ausmelt sab saum toj-blowing submerged tsuag qiang txheej txheem tau dav siv nyob rau hauv kev lag luam zus tau tej cov non-ferrous hlau thiab precious hlau thiab high-kub kev kho mob ntawm ntau yam pov tseg. Thaum kawg ntawm xyoo 2003, suav nrog Ausmelt qhov kev nthuav qhia tshiab cog hauv South Australia, 16 smelters thoob ntiaj teb siv cov txheej txheem Ausmelt rau kev tsim khoom lag luam, suav nrog Jinchang smelter hauv Tongling, Tuam Tshoj, cog tooj liab hauv Is Nrias teb, thiab cog tooj liab ntawm cov khoom siv rov ua dua tshiab. tooj liab chaw tsim tshuaj paus ntawm Korean Zinc Company. Cov txheej txheem Ausmelt tuaj yeem yog ib qho los yog ntau lub qhov cub teeb tsa, thiab feem ntau tsis xav tau cov khoom siv nyuaj thiab cov tshuaj tua hluav taws xob. Vim lub simplicity, yooj thiab siab zog efficiency ntawm cov txheej txheem, cov khoom siv ntawm cov txheej txheem Ausmelt yog kuj tsawg. Cov txheej txheem Ausmelt tsom rau kev txo qhov loj thiab qhov nyuaj ntawm cov khoom siv peripheral, yog li kev hloov pauv qis hauv lossis ib puag ncig Ausmelt rauv ua haujlwm tso cai rau cov neeg siv khoom kom txo tau qhov ntsuas ntawm cov roj av kho, tshwj xeeb tshaj yog sulfur fixation thiab acid nroj tsuag, roj thiab roj xa cov tshuab. Cov khoom siv raw yog yooj yim thiab pub tsis tas yuav ziab thiab sib tsoo.
