A vertical solid-liquid contact apparatus including a plurality of stirring chambers disposed vertically adjacent to each other in series, a plurality of partitioning plates each partitioning an adjacent pair of the stirring chambers and provided with a communicating hole for communication between the adjacent pair of the stirring chambers, and a liquid inlet and a solid inlet provided at an upper part and a lower part of the apparatus. Each stirring chamber having an inner side wall defining the stirring chamber, a radially ejecting stirring blade, and at least one baffle fixed on the inner side wall. The stirring blade and the baffle are positionally biased to a lower side of the stirring chamber. The apparatus provides a good uniformity of solid-liquid flows and a high contact efficiency, is also simple in structure and allows easy scale-up.
