ABSTRACT OF THE DISCLOSURE A novel method and apparatus are provided for mixing and dissolving solid and liquid substances. The method includes the steps of first keeping both the solid and liquid substances to be mixed continuously in a constant circulation inside an in-line mixing zone surrounded axially by the mixing/ reactor zone using an external source of mixing energy to maintain a mix- ture or solution. The next step involves continuously internally recircu- lating a portion of the mixture or solution along with an additional por- tion of the mixture or solution from an external source in a separate concentric circulating zone within the mixing/reactor zone. The next step in- volves continuously withdrawing a portion of the mixture or a portion of the solution from the concentric zone through an annular outlet connection zone leading to the mixing/reactor zone and thence through an annular inlet connection zone leading to the concentric zone. The next step involves continuously discharging a solution from the mixing/reactor zone through a separate annular discharge zone and through outlet zones to a level-controlling dis- charge zone. The final step includes continuously and controllably supply- ing an amount of both the solid and the liquid substances to the mixing/reactor zone, the supplied amount being equal to the discharged solution withdrawn through the discharge zone. The apparatus for performing the method com- prises a specially configured loop-type reactor having a special mixing and dissolving chamber with internal recirculating means and separate with- drawal means to external recycling means. By this method and apparatus, a solution is obtained in a continuous flow.
