I note, rio, are going back to the briguette technology Moon.
The company has tested its BioIron iron-making process at a small-scale pilot laboratory in Germany over 18 months "using batches of 1,000 golf ball-sized iron ore and biomass briquettes".Professor Dongke Zhang, the director of the Centre for Energy at the University of Western Australia, said there was no doubt it was technically doable, and he had done a similar experiment in his lab 16 years ago.
He explained the biomass absorbs the microwave energy and turns it into heat at a high enough temperature for the iron ore reduction to occur.

Western Australian farmers produce over 10 million tonnes of waste biomass every year, much of which is not utilised commercially.
