Typical examples of the coalbased process include the SL/RN and ACCAR processes. The coalbased DR process is more popular in India and China. Different types of reactors, such as shaft furnaces, fluidized beds, rotary kilns, and rotary hearth furnaces
Direct Reduction Process an overview ScienceDirect Topics. However in the coal/oilbased DR process, the reducing gas is generated from hydrocarbons (primarily coal, but sometimes oil and natural gas) in the reduction zone of the furnace, which is typically a rotary
A rotary hearth furnace is a directreduction device that enables to recover valuable metals from dust produced during the steelmaking process, as well as to produce directreduced iron from fine ore

Redsmelt NST (New Smelting Technology) is a new ironmaking process based on two reduction steps: prereduction in a rotary hearth furnace and DRI smelting in an innovative oxycoal reactor.
The metallurgical dusts can be gr0recycled in rotary hearth furnaces (RHF) by means of direct reduction after adding into carbonbased composite epellets. While iron resources in the dust are recycled,
