Uranni уег оstida ishqorlash qiyin geterogen, uran tarkibli birikmalar va jinslar, bilan o'zaro ta`sirlashganda yaxshi ertuvchan birikmalar hosil qiluvchi, reagentga ega ho`lgan, qattiq fazani siiyuq fazaga o'tkazuvchan jarayondir. Reagentlaning uran tarkibli jinslar bilan o'zaro ta ’siri yer osti ishqorlashga xos, odatda, diffuzion hodisaga nisbatan ancha tez kechadi. Bu hol eritma oqimiga nisbatan rudah jinslarda nihoyatda kam tarkibli, qayta shakllangan uran birikmalarida ancha vuqori eruvchan qobiliyatidan yuzaga kelgan.

Tayanch iboralar: urani ishqorlash, sulfat kislota, diffuzon hol, ishqorlash kinetikasi, reaksiya, diffuziya teziigi,konsentrstsiya gradiyent, gaz doimiyligi, eritma qayishqoqligi, qattiq faza yuzasi, suyuqlik pardasi. reagent sarfi tezligi,tezlik konstantasi.

Leaching of uranium from rocks is the difficult heterogeneous process happening on the limit of the section firm and liquid containing the reagent capable to form at interaction with uranium bearing minerals or breeds well soluble connections.Chemical interaction of reagent with uranium bearing breeds proceeds, as a ride, quickly enough in comparison with the diffusive phenomena characteristic of process of UL (Underground leaching). This circumstance is caused by reactionary ability of uranium, his extremely small contents in ore breeds in relation to a solution stream, quite high values of solubility of again formed compounds of uranium.

Key words: leaching of uranium, dipping acid, diffusion phenomena, kinetics of leaching, reaction, rate of diffusion,concentration gradient, gas contact, solvent viscosity, surfaced of solid, liquid film, consumption rate of reagent,kinetic constant.
