The results showed that the dissolution rate increased with increasing solution concentration and reaction temperature, and increased with decreasing particle size and solid to liquid ratio. It was also determined that stirring speed had no significant effect on dissolution rate. The dissolution process was examined according to homogeneous and heterogeneous reaction kinetic Model. The dissolution rate was found to be based on the first order pseudo homogeneous reaction model. The activation energy of the dissolution of tincal in ammonium chloride solutions was determined to be 82.73 kJ . mol(-1).zhinfo:eu-repo/semantics/closedAccessBoron MineralsTincalAmmonium ChlorideLeaching KineticsBoric AcidArticle255Q4Q4767773WOS:000266252500002
