Direct smelting process for stainless steel crude alloy ...

Stainless steel crude alloy recovery from direct smelting of low-grade chromite, nickel laterite and manganese ores was investigated. The mixed low-grade ores were directly smelted in an elevator furnace at smelting temperatures ranging from 1550 to 1600 °C. Smelting experiments were conducted in a laboratory elevator furnace equipped with 8 U-shaped high-quality …

Nickel and Cobalt Production - ScienceDirect

The first principle of ferronickel smelting is that Ni and Fe oxides are easily reduced to metallic nickel and iron by Reactions and : (2.2.1) C in calcined concentrate + NiO → 800 ° C CO + Ni ° metal (2.2.2) C in calcined concentrate + FeO → 800 ° C CO + Fe ° metal while other oxides, e.g., Al 2 O 3, MgO, are not reduced.This situation arises because oxygen bonds with Al and Mg much ...

Nickel - USGS

Domestic production of stainless steel and related nickel consumption decreased substantially in the first half of 2020, but most of the leading domestic stainless-steel producers reported relatively robust recovery in the third quarter. Total domestic production of stainless steel in 2020 was estimated to have decreased by approximately 10%.
