MANGANIFEROUS IRON ORES. - USGS
allow the extensive utilization of low-grade manganiferous iron ores. He suggests that instead of adding large quantities of ferro- manganese or spiegeleisen to steel for deoxidizing at the end of the heat, a manganiferous pig iron containing about 3 or 4 per cent of manganese be used in the bath so that the deoxidation necessary at the end of a heat may be reduced to a minimum. It is believed ...
Steam Reforming of Tar Using Low-Grade Iron …
The utilization of low-grade iron ore in the steam reforming of tar significantly increased the total gas production, especially H2 and CO2.
