Experimental study for obtaining bricks from the use of mining tailings cyanide process

Abstract

Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.An experimental prototype that uses tailings miners of cyanide process has been designed and built to the manufacture of building bricks. This prototype is composed of three units. The first unit, includes a thickener and a neutralizer tank. The second unit, a filter, a mixer and a molder. The third unit comprising a dryer - oven. The develop process allows the entered tailings to be separated into liquid and solid, to be neutralized later caro acid. Then, the resulting mixture will be filtered and will be added the necessary additives (clay or green clay) for the constitution of the brick. Finally, this mixture will pass through a drying stage, where the furnace oven temperature reached one thousand degrees centigrade.
