Abstract The invention relates to a method for directing a desired amount of gas below the liquid surface in a solution reactor, to mix the bubbles as effectively as possible with a suspension of a pulverous solid and a liquid, and to produce in the mixed gas-liquid-solid suspension a strong, suspension-maintaining flow field which is downward in the center of the reactor (1) and upward along its sides. A so-called gls-mixer (3) according to the invention consists of a circular plate (6) fitted at the lower end of a rotating shaft (2) suspended by its upper end, vertical dispersion blades (7) situated radially at the edges of the circular plate (6), and baffles (9) attached to the dispersion blades (7) by means of arms (8). An upwards directed gas-feeding conduit (4) is fitted at the bottom of the reactor (1), and from this conduit the gas jet discharges to the center point of the circular plate (6). Figure 2 has been selected for the abstract.
