Njira ya Copper powder oxidation. Reaction equation:

4Ku+O2→ 2Cu2O

2Cu2O+2O2→4CuO

CuO+H2SO4→CuSO4+H2O

CuSO4+Fe→FeSO4+Cu↓

2Cu+O2→ 2CuO

Njira yogwiritsira ntchito:
Copper ufa makutidwe ndi okosijeni njira amatenga mkuwa phulusa ndi mkuwa slag monga zopangira, amene anawotcha ndi kutenthedwa ndi mpweya kwa makutidwe ndi okosijeni koyambirira kuchotsa madzi ndi zosafunika organic mu raw materials.The kwaiye okusayidi pulayimale utakhazikika mwachibadwa, wophwanyidwa ndiyeno pansi makutidwe ndi okosijeni yachiwiri ku kupeza oxide yakuda yamkuwa. The yosakongola mkuwa okusayidi anawonjezedwa mu riyakitala chisanadze zodzaza ndi 1: 1 sulfuric acid. Kuchitapo kanthu pakuwotha ndi kusonkhezera mpaka kachulukidwe kamadzimadzi kawirikiza kawiri kuposa choyambirira ndipo pH mtengo ndi 2 ~ 3, komwe ndi komaliza kwa zomwe zimachitika ndikupanga njira yothetsera mkuwa wa sulfate. Pambuyo pa yankho latsala kuti liyime kuti limveke bwino, onjezerani zitsulo zachitsulo pansi pa kutentha ndi kusonkhezera m'malo mwa mkuwa, ndiyeno muzitsuka ndi madzi otentha mpaka palibe sulfate ndi chitsulo. Pambuyo centrifugation, kuyanika, oxidizing ndi Kukuwotcha pa 450 ℃ kwa 8h, kuzirala, kuphwanya mpaka 100 mauna, ndiyeno oxidizing mu ng'anjo makutidwe ndi okosijeni kukonzekera mkuwa okusayidi ufa.
