    摘要: The present invention is directed to a process of making fired mineral pellets by mixing particulate mineral material with moisture and binder comprising substantially water soluble organic polymer to form a moist pelletizable mix, pelletizing the moist mix by a tumbling process to form green pellets and firing the green pellets, characterized in that the binder comprises alkali metal silicate in a dry weight amount which is either (a) above 0.13% based on moist mix or (b) above 0.08% based on moist mix and at least three times the dry weight of substantially water soluble organic polymer.

    摘要: Briquettes for the liquefaction of metallurgical slag are formed from a mixture containing, by weight, 85-98% slag from secondary aluminium processing, 1 to 8% polyvinyl acetate dispersion as the polymeric bonding agent and the remainder water, the briquettes containing water in the form of residue humidity at a quantity of maximally 1.5%, ideally no more than 0.5%, in relation to the overall weight of the briquettes, and the briquettes have a specific weight of 1,500-5,000 kg.m−3 and a compression strength of at least 20 MPa. Ideally, the mixture contains 90-92% slag from secondary aluminium processing, 1 to 3% polyvinyl acetate dispersion and the remainder water. The mixture may also contain 0.5-2% unsaturated acid, selected from the group containing oleic acid and/or palmitic acid and/or stearic acid, as a hydrophobic ingredient. The ideal shape of the briquettes is cylindrical.
