This work aimed to implement a screening experiment, to study the effects of different processing and formulation factors on the elimination of carbonates from Moroccan oil shale employing Plackett?Burman screening design. Different factors were proposed for study, such as temperature (?C), concentration (mol/l), ratio (s/l), processing time (h), mean particle size (mm), type of acid (CH3COOH, HCl), origin of row material (Tarfaya, Timahdit) and agitation (Yes, No). The quantity of carbonates

The results revealed that concentration, ratio, processing time, mean particle size, type of acid and the origin of row material (Tarfaya, Timahdit), showed a significant effect on the quantity of carbonates eliminated, while the temperature and agitation had no effect. The predicted values were in agreement with the experimental values with a coefficient of determination (R2) of 0.99. The model has been validated by experiments subsequent to optimized conditions.
