There is disclosed a method for removing soluble constituents in solid mixtures which consist of injecting a solvent at a high pressure to a slurry of the solid mixture moving along a flow path. An apparatus embodying this method is also disclosed which includes a reactor having a high pressure chamber which comprises at least one nozzle surrounding the flow path of the slurry through which the solvent is injected. Each nozzle is composed of two cylindrical components spaced from each other, the separation between them defining a plurality of axially aligned circumferential openings through which the solvent is injected. A system comprising such an apparatus may further comprise filtering means to separate the soluble constituents from the cleaned solid mixture.
