Abstract
It is shown that an efficient way to accelerate mass transfer between a solid particle and a liquid surrounding it can be application of energy of shock wave propagating in the gas-saturated pulp containing mineral particles. An estimation has been made of the possible increase in the rate of dissolution of the solid particle situated in the liquid with evenly distributed gas bubbles under the action of the shock wave on such a medium. Experiments have been performed to ascertain the effect of shock waves on the mass transfer in a model NaCl crystals-water system. The obtained data indicate that particle dissolution occurs much faster under shock-wave than under acoustic agitation of the medium.
