Apparatus for promoting controlled gas-solids reaction in elongated treatment zone utilizing means for producing vibratory action for impelling progressive movement of charge and separating discrete particles of charge in each increment of applied forces with reactive gas introduced in starvation amount at spaced points along course of movement entering spaced between separated particles. Impervious support surface of reaction zone provides controlled heat transfer during reaction and movement rate induced by vibratory action determines solids retention time in treatment zone. Treatment suitable for chlorination, sulfation, oxidation and reduction. Iron pyrites treatment for iron and elemental sulfur recovery at low cost.
