Zirconium Metal – Provide you with various industry ...Dec 24, 2019 · Zirconium is an expensive corrosionresistant metal material with excellent resistance to corrosion by acids and alkalis. In some media, it even exceeds metals with good corrosion resistance such as niobium and titanium. Zirconium alloys have been gradually used in recent years as structural materials for equipment and pipelines in the chemical industry due to their good corrosion resistance.
Loions of DepositsZirconium is also produced as a byproduct of mining the titanium minerals ilmenite and rutile. Niobium and tantalum are commonly found in the minerals pyrochlore and columbite. Cobalt is mined specifically from ores like cobaltite, but also as a byproduct of copper and nickel mining (Raymond, 1995).
