ABSTRACT
/Full article available only in Russian language/

One of fundamental dependence for estimation of metals ISL process
effectiveness is working solution productivity function of block operation
time. As a rule, that dependence is set by test at pilot site before the whole
deposit exploitation. Other way to set that dependence consists of uranium
ISL, kinetics known differential equations solving, which still does not give
reliable results. The report offers experimental analytical method of that
task - solution based just on one experimental dependence – uranium
recovery coefficient dependence on operation time of block, site or deposit.
Mathematical model forecasts by exponential curve the metal assay in
pregnant solution within any interval of blocks operational time and for any
liquid to soil ratio. Obtained regularities allow to calculate production,
waste and metals recovery coefficient from subsurface.
