Copper yog ib qho tshuaj lom neeg hlau thiab cov kab mob tseem ceeb rau tib neeg lub cev. Tooj liab kuj yog thawj cov hlau pom los ntawm tib neeg thiab yog cov hlau dav siv los ntawm tib neeg, koom nrog cov hlau hnyav.
Tooj liab yog thawj cov hlau siv los ntawm noob neej. Raws li ntxov raws li nyob rau hauv prehistoric lub sij hawm, tib neeg pib extract qhib-qhov tooj liab mines thiab siv cov tooj liab tau los ua riam phom, style thiab lwm yam khoom siv, kev siv tooj liab muaj kev cuam tshuam loj heev rau kev vam meej ntawm tib neeg kev vam meej thaum ntxov. Tooj liab yog ib yam hlau uas pom nyob rau hauv lub ntiaj teb lub crust thiab nyob rau hauv dej hiav txwv. Cov ntsiab lus ntawm tooj liab nyob rau hauv lub ntiaj teb crust yog hais txog 0.01%, thiab nyob rau hauv ib tug neeg tooj liab deposits, cov ntsiab lus ntawm tooj liab tuaj yeem ncav cuag 3% ~ 5%. Feem ntau ntawm cov tooj liab nyob rau hauv qhov muaj xws li cov tebchaw, xws li tooj liab minerals. Copper minerals aggregate nrog rau lwm yam minerals los tsim tooj liab ores, uas yog mined thiab beneficiated los ua tooj liab concentrates nrog qib tooj liab. Nws yog tib cov hlau uas tuaj yeem tsim tau ib txwm muaj ntau, thiab tseem muaj nyob rau hauv ntau yam ores (xws li chalcopyrite, chalcopyrite, porphyry, chalcopyrite thiab malachite), thiab tuaj yeem siv rau hauv daim ntawv ntawm cov hlau monomorphic xws li tooj dag, tooj liab. thiab lwm yam alloys rau industrial, engineering thiab technologies lub hom phiaj.
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.
