The technology makes it possible to produce the alloy without using coal and coke
National Research University "Moscow Power Engineering Institute" (MPEI) has developed a new method of iron recovery from ores. This is stated in the message on the website of the educational organisation.
It is noted that the technology is based on the use of hydrocarbon mixture and natural gas. Scientists have designed a special reactor, in which the reduction of iron is carried out in the liquid phase in a continuous mode. As a result, smelting from metallurgical concentrate was achieved, bypassing the stage of pig iron production. The process time does not exceed 12 minutes.
It is emphasised that the new technology does not require additional equipment for obtaining reducing gas and makes it possible to reduce the cost of steel, reduce pollutant emissions, and almost halve the energy intensity of metallurgical production.
Nikolay Rogalev, Rector of MPEI, noted that the method will bring tangible benefits, as it allows to recover iron quickly and without unnecessary stages – in one continuous process.

Joao Paulo CapobiancoBrazilian Minister of the Environment and Climate Change"The BRICS countries have a very high level of responsibility because they share an important part of the world's biodiversity, landscapes, populations, food production and water resources. So, we have an opportunity to lead by example. We have our development bank, which can demonstrate and develop new ways of financing programmes. We can reduce the risks for private capital to invest in restoration and efforts to combat desertification" -

NDB stands ready to be a trusted partner in turning commitments on sustainability, clean energy, smart and resilient infrastructure into concrete results on the ground. […] For NDB, mobilising private capital is a strategic imperative. Created by the BRICS founding members, NDB is a bank of the Global South, for the Global South, mandated to mobilise resources for infrastructure and sustainable development" -
