Iron ore powder was isothermally reduced at K with hydrogen/carbon monoxide gas mixture (from 0vol%H 2 /100vol%CO to 100vol%H 2 /0vol%CO). Results indicated that the whole reduction process could be divided into two parts that proceed in series. The first part represents a doublestep reduction (Fe 2 O 3→Fe3O4→FeO), in which the kinetic condition is ...
The team at Form Energy describe their new battery as a multiday energy storage system—one that can feed electricity to the grid for approximately 100 hours at a cost that is significantly lower than lithiumion batteries.. The basic idea behind the ironair battery is that it takes in oxygen and then uses it to convert iron inside the battery to rust, later converting it back to iron again.

Today's steelmaking from iron ore is globally a main source for CO 2emissions causing global Sweden more than 10% of all CO 2 emissions originate from the reduction process of iron ore to iron. When an environmentally friendly chemical reduction is found in an orebased laser additive manufacturing process, CO 2 emissions will be avoided, to an extent proportional to its use.

In America about 1520 million tons of iron ores were separated with ferrosilicon in 1952. A powder with about 15% Si=content is used because in it the magnetic properties are well distinguished and the specific gravity is high. With a Si=content of 1820% the spec, gr. is lower and the limit of magnetizability is near.
