Kev faib tawm ntawm cov ntawv uas muaj nyob rau hauv qhov xwm txheej
Ntuj tooj liab ------ muaj ntau tshaj 99 feem pua tooj liab, tab sis muaj tsawg heev reserves.
Oxidised tooj liab ores ----- kuj muaj tsawg tus lej
Copper Sulphide Ore ----- muaj tooj liab tsawg heev, feem ntau nyob ib ncig ntawm 2 - 3%, ntau tshaj 80% ntawm lub ntiaj teb tooj liab yog refined los ntawm tooj liab sulphide ore.
Kev faib cov txheej txheem ntau lawm
Copper concentrate ---- ore nrog cov ntsiab lus tooj liab siab xaiv ua ntej smelting.
Crude tooj liab ------ tooj liab concentrates smelted nrog ib tug tooj liab ntsiab lus ntawm 95-98%.
Ntshiab tooj liab ------ tooj liab nrog cov ntsiab lus ntawm 99% los yog ntau tshaj tom qab hluav taws-refining los yog electrolysis. Hluav taws kub refining yields 99-99.9% ntshiab tooj liab, thiab electrolysis tuaj yeem ua tooj liab 99.95-99.99% ntshiab.
Main alloy muaj pes tsawg leeg classification
Brass ----- tooj liab-zinc alloy
Bronze ----- tooj liab tin alloy, thiab lwm yam (ntxiv rau zinc npib tsib xee, ntxiv lwm cov ntsiab lus ntawm cov alloy hu ua tooj liab).
Dawb tooj dag ----- tooj liab-cobalt-nickel alloy
Cov khoom lag luam kev faib tawm
Tube tooj liab, tooj liab bar, tooj liab hlau, tooj liab phaj, tooj liab strip, tooj liab bar, tooj liab ntawv ci, thiab lwm yam.
Txawm koj xav taucov kav dej tooj liab, tooj liab rods ,tooj liab daim hlau, peb muaj cov khoom thiab kev txawj ntse kom tau raws li koj xav tau.
