Aim of this Study. The purpose of this study was to develop a new hybrid model (i.e., the complete ensemble empirical mode decomposition with adaptive noise (CEEM-DAN)–S-curve model) to clarify the chromium ore consumption mechanism. This model identifies the factors that dominate the consumption of chromium ore.

· The South African chromite concentrate consisted mainly of the chromite spinel phase and small quantity of siliceous gangue, and was assayed at 42.55% Cr 2 O 3 with a low Cr 2 O 3 /FeO ratio of 1.99. The magnetite concentrate is expected to improve the softening-melting performance of sinter products from the chromite concentrate.

· Ferrochrome is an important additive in the production of alloy steel. According to the carbon content , it is classified as high-carbon ferrochrome (carbon 4–8%), medium-carbon ferrochrome (0.5–4%), low-carbon ferrochrome (0.15–0.50%), micro-carbon ferrochrome (carbon 0.06%), and ultra-micro-carbon ferrochrome (less than

It is clear that the largest operating cost in the FeCr production process in South Africa is electricity – in 2016 it was a staggering 38.1% of the total production cost. The cost of fluxes and electrode paste is a mere 3.1%; however, fluxes can play an important role in lowering the energy requirement for smelting.
