An　enhanced　leaching　of　Li　from　alpha-spodumene　was　carried　out　using　a　mixture　of　hydrofluoric　and　sulfuric　acid　(HF/H2SO4)　as　the　medium.　Based　on　the　optimized　leaching　conditions,　the　leaching　kinetics　of　Li　was　investigated　in　an　ore/HF/H2SO4　ratio　of　1:3:2　g:mL:mL　with　leaching　temperature　ranging　from　50　to　100　degrees　C.　The　results　indicate　that　the　leaching　kinetics　of　Li　fitted　well　with　a　model　based　on　the　shrinking　core　model.　In　addition,　the　leaching　rate　of　Li　was　controlled　by　chemical　reactions　and　diffusion　through　the　product　layers.　The　apparent　activation　energy　E-a　was　calculated　to　be　32.68　kJ/mol.　Solid　films　were　formed　because　of　the　generation　of　insoluble　products　such　as　cryolithionite　(Na3Li2Al2F12),　cryolite　(Na3AlF6),　calcium　fluoride　(CaF2),　potassium　cryolite　(K2AlF5),　aluminum　fluoride　(AlF3),　and　fluorosilicates　(Na2SiF6　or　KNaSiF6).　Furthermore,　the　effects　of　the　ore/HF　ratio　and　leaching　temperature　on　the　leaching　behavior　of　Li,　Al　and　Si　were　investigated.　The　results　indicate　that　the　ore/HF　ratio　and　leaching　temperature　could　clearly　affect　the　distribution　of　HF　molecules　on　the　leaching　of　Li,　Al　and　Si,　which　are　important　for　the　selective　leaching　of　Li　over　Al　and　Si　with　this　fluorine-based　chemical　method.
