ABSTRACT: The potential of using Tin tailings industrial waste, from the mineral processing industry for the
production of refractory bricks for furnaces lining was studied. The waste was obtained at Tin
Ore beneficiation plant, screen and sieve. The sieve Tin tailing was then used in the production
of refractory bricks. The properties namely: chemical analysis firing shrinkage, porosity, cold
crushing strength, refractoriness and thermal shock resistance were determined. The result
obtained show that cold crushing strength and thermal shock increased as the sieve size
decreases, which means that high strength bricks can be made from this waste. Also the brick
made with 0.9mm sieve size has the highest value of firing shrinkage, lowest value of porosity
and with acceptable value of thermal shock resistance. This industrial waste has refractory
properties that can be compared with Indian fire clay refractory. Hence, this waste can be
employed in refractory bricks production for furnace lining.
