Abstract
A process for the reduction of iron oxides to produce molten iron in which olivine is introduced into a blast furnace in addition to iron oxide bearing materials and in which there is high content of alkali metal oxides in the materials charged into the furnace, resulting in minimizing or preventing 'scaffolding' and improving the operation of the blast furnace. The disclosure also includes sinters and briquettes which contain olivine and processes of preparing them, and processes for furnace operation including the charging of such sinters or briquettes.
