Influence of the flow rate of inert gas on the rate of reduction of chromite ore

What is it about?

Carbothermic reduction of ores such as chomite ores involves the generation of CO gas by the oxidation of carbon. The CO gas reduces the ore and produces CO2 gas. The CO2 gas, in turn, reduces carbon to produce CO gas. In cases like these the flow rate of inert gas which is usually passed through the system where reduction occurs in laboratory experiments will affect the rate of reduction. This phenomenon has not been studied in detail so far. This is thh first publication which focuses on this

Why is it important?

It is found that the rate of carbothermic reduction of oxide ores is influenced extensively by the flow rate of inert gas, in a complex manner. This phenomenon can be used to device processes that can enhance the rate of reduction of these ores at low temperatures. A process has been patented by the author on the basis of this phenomenon.
