Abstract:

     Pilot-plant-scale tests of “desliming-spiral chute re-election” with inclined plane thickener have been conducted in a typical domestic laterite weathering titanium plant. Good test indicators are achieved: 1) amount of clay removal can reach 55%~60%, TiO₂ in clay is only 0.5%~0. 9% and the loss rate of metal in mud is only 5% to 8% by using high efficiency inclined plate thickener; 2) after desliming, the same spiral chute was used to gravity separation. The content of TiO₂ in concentrate can reach 33.54%, and the recovery rate is 86.58%; 3) the process is simple, the production operation is feasible by using the high efficiency inclined plate thickener; 4) the results of this study can provide reliable technical support for the technological transformation of the mineral processing plant.
