In　order　to　study　the　alkaline　leaching　process　of　the　boron　ore　further,　the　boron　bearing　tailings　from　Kuandian　calcined　at　700℃　were　treated　as　the　raw　material　in　this　article,　on　the　basis　of　the　shrinking　core　model,　the　kinetic　equation　of　alkaline　hydrolysis　reaction　in　NaOH　solution　for　boron　of　ore　samples　was　deduced,　and　the　alkaline　hydrolysis　experiment　was　conducted　on　the　raw　material,　the　kinetic　equation　theoretically　deduced　was　fit　and　validated　according　to　the　experiment　results.　The　research　shows　that　the　alkaline　hydrolysis　reaction　process　of　boron　under　the　experimental　conditions　coincide　well　with　the　shrinking　core　model,　the　kinetic　equation　of　boron　in　the　alkaline　hydrolysis　reaction　process　is　t=42.4954[(1-X)-1/3+1/3ln(1-X)-1]+0.0338[(1-X)-2/3-1],　the　kinetic　process　of　it　is　mainly　controlled　by　diffusion　mechanism,　elevating　the　temperature　of　solution,　increasing　the　concentration　of　NaOH　solution　and　reducing　the　particle　size　of　ore　samples　are　conducive　to　shorten　the　alkaline　hydrolysis　time　and　complete　the　reaction　as　soon　as　possible.　The　kinetics　establishes　a　preliminary　theoretical　foundation　for　the　alkaline　treatment　application　of　the　boron　ore.　©　2016,　Materials　Review　Magazine.　All　right　reserved.
