Mass transfer between solid and liquid in gas stirred cylindrical vessels has been analysed both theoretically and experimentally. To this end, starting from an appropriate “single particle‐fluid correlation”, a relationship applicable to a system of suspended solids has been deduced and represented according to: . On the basis of this, dissolution of solids in two different aqueous models of gas stirred ladles has been investigated and it has been demonstrated that the correlation produces estimates which are in reasonable agreement with the experimental observations. Furthermore, it is shown that the present correlation has a form analogous to the one, derived much earlier by Kolmogoroff from the theory of isotropic turbulence.
