Effects of direct reduction process on the microstructure

2020-10-1 Abstract A coal-based direct reduction process was used to recover the ferronickel from low-grade nickel laterite ore. The effects of basicity on the compressive strength, metallization rate, microstructure, and reduction characteristics of carbon-bearing

Direct Reduction of Limonitic Laterite Nickel Ore with

The increasing demand for stainless steel and the scarcity of sulfide nickel ore affect the increase of laterite nickel ore processing. 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

Direct reduction of garnierite ore for production of ferro

During World War II, the Nippon Yakin Kogyo Co., Ltd. produced sponge iron with the Krupp-Renn process at the Oheyama Works from laterite ore mined at the nearby Oheyama Mine. In 1952, we switched the raw material to imported garnierite ore and started the production of ferro-nickel for stainless steel manufacturing.

Direct Reduced Iron Industrial Efficiency Technology

2017-9-13 Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.
