Abstract
A process is disclosed in which coarse silica, calcium oxides and magnesium oxides are treated in a ball mill together with grinding aids and cold-strength binders. This material is then agglomerated with water to produce a product that reacts at elevated temperatures, e.g. in a fluidized bed reactor, to produce synthetic silicates.
