Abstract (en)

[origin: WO9960175A1] The invention concerns agglomerating or briquetting of a mineral in fine granular state of less than 5 mm for smelting which may be mixed with fines by conglomerating the mineral with a binder prepared from at least sodium silicate, acrylic resin, vinyl alcohol, borax, magnesium chloride and if required during smelting an anti-oxidant such as sodium. The bound conglomerates or briquettes have superior strength properties.
