- Abstract
The formation mechanism is considered, as well as the step and integral constants are calculated for carbamide complex protonation in the solutions of sulfuric acid. It is established that they can be catalysts when adsorbing on the mineral surface. The possibility of carbamide use is shown by the example of leaching the oxidized copper ore with simultaneous decrease in c(H2SO4) from 2 to 1 %.
