ABSTRACT
Signi´Čücant quantities of sludge and slag are generated as waste material or by-product every day from steel industries.They usually contain considerable quantities of valuable metals and materials. It is generally possible to recover some values by physical or chemical mineral processing techniques. Briquetting is such a process to re-cycle this waste coke oven sludge as a useful fuel. In the present study experiments were conducted to determine optimum parameters of briquetting like binder content, water content, pressure and temperature of heat treatment .shatter resistance tests were carried out on briquettes obtained under different conditions. The physical properties of the feed material, the end use of the briquettes and the cost of binder addition have to be taken into account before a selection is made. In the experiments different binders used are starch, bentonite, molasses, iron ore fines and water.The briquettes are obtained at high pressure and they undergo mechanical and treatment according to the characteristics of the processed material, the binder used and the desired product.
