    Briquetting of Rosetta ilmenite ore with different organic binder and its reduction in hydrogen in the temperature range of 800÷1200 degrees of Celsius
    (Wydawnictwa AGH, 2009) Abd el-Gawad, Hala H.; El-Hussiny, Naglaa A.; Wassf, Marguerite A.; Kalifa, Mohamed G.; Iskander, Berlanty A.; Shalabi, Mohamed el-Menshawi H.
    Fine grained ilmenite ore was briquetted with different amounts of molasses or pitch and pressed under different values of pressure was studied in this investigation. The results show that optimal amount of added molasses and pitch were 1.5%, the pressure was fixed to 294.3 MPa. Furthermore, the characteristics of raw materials was examined by different methods of analysis, such as x-ray and screen analysis. The produced briquettes were then reduced by different amounts of hydrogen by different temperatures and the reduction kinetics was determined.

    New technology and the equipment for brown coals, peat and slimes briquetting
    (2007) Bondarenko, Volodimir Illič; Pilov, Petr Ivanovič
    The new briquetting technology of secondary fuel and brown coal is developed at National Mining University, Dnipropetrowsk, Ukraine. It is based on the adhesion and chemical processes, proceeding in viscously plastic systems, formed by thin disperse particles of coal and occurrence their knitting properties. It is possible to make composite fuel which components is the mix of coal and anthracite slimes, brown coals, and various waste products containing organic substances.
