Production Process of Ferronickel - Miss Rifka

04/02/2012  Production process of ferronickel consists of four main steps. Drying: elimination of most or a substantial portion of free moisture content of the nickel ore; Calcination-reduction: elimination of the remainder of the free ore moisture and its crystalline water, preheating of the ore, and reduction of a substantial portion of the nickel and a controlled portion of the iron; Electric furnace ...

Ferronickel - an overview ScienceDirect Topics

The production of ferronickel from lateritic ores follows a pyrometallurgical route including three important stages: (1) prereduction in rotary kilns; (2) reductive smelting in EAFs; and (3) ferronickel enrichment-refining in converters. 30 During reductive smelting, two separate phases are formed into the EAF: the ferronickel alloy, and the slag that contains oxides from the gangue material ...

The evolution of the Greek ferronickel production

Ferronickel (with 15% Ni) produced in the E/F, was upgraded to 90-95% Ni in an O2 converter. Raw Ni was then electrolyzed to pure Ni. The LM process was not applied for very long however, due to various problems. So, the Larco process was developed, i.e., pre-reduction in R/Ks, smelting of the calcine in E/Fs for ferronickel production (15% Ni) and enrichment to 20% Ni, in an O2 converter ...
