ABSTRACT:
A method of bonding particulate material, especially such material which contains iron or zinc oxides, e.g. steelmaking fume or blast furnace dust, by treating the material with at least aqueous formic acid to produce an acid solution containing metal ions, and then allowing or causing the pH of the solution to increase so as to form a metal hydroxide to bond the material to consolidated form.
