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. This process of directly reducing the iron ...
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...
So called Carbonyl Refining Method for Laterite Ore was developed by INCO up to the full scale pilot stage and included partial reduction of nickel and iron by COCO 2 gas mixture and direct extraction of nickel from ore in the form of nickel carbonyl. The product of the refining was forecasted as ferronickel with FeNi ratio of 1.41
One of the processes that has been proven can be applied to process laterite nickel ore is direct reduction. In the direct reduction, the reduction atmosphere was adjusted by controlling the volume of CO and CO2 from carbon source materials, such as coal, charcoal, and green cokes. This research aims to analyze the effect of reducing agents type on nickel limonitic nickel briquettes on Ni and Fe content …

In laterite nickel processing by direct reduction, the challenges are to conduct selective reduction of nickel and to let iron unreduced. The addition of additive in the direct reduction process is needed to achieve this selective reduction. Additives used for the selective reduction includes Na 2 SO 4, MgCl 2, CaSO 4, NaCl and CaCl 2 ·H 2 O.
