direct reduced nickel

Direct Reduction Process an overview ScienceDirect Topics

The gaseous (or carbothermic) reduction of nickel oxide, obtained by dead roasting of nickel sulfide matte or concentrate, is an important intermediate step for nickel production. In the Mond process, crude nickel is obtained this way before undergoing refining by carbonylation. Sponge iron can be produced in the form of Direct Reduced Iron

Effects of direct reduction process on the microstructure

Oct 01, 2020· Where M Ni is the metallic nickel content (wt%), T Ni is the total nickel content (wt%), M Fe is the metallic iron content (wt%), T Fe is the total iron content (wt%). All iron and nickel contents are determined by chemical titration. The Iron in direct reduced iron was developed by iron trichloride decomposition‑potassium dichromate titration.

Direct Reduced Iron (DRI) Cargo Handbook the world's

Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.
