The use of 2, 6-di-tert-butyl-4-methylphenol as additive for delaying the chemical degradation of alamine 336-tridecanol-kerosene during the recovery of uranium from acidic sulfate media

Solvent extraction processes are used worldwide for the production of base and strategic metals and in the nuclear industry for the reprocessing of used nuclear fuels. Nevertheless, hydrometallurgists may still encounter technical problems in SX plants. These problems include progressive degradation of the extractants with an associated loss of extraction capacity. All of these problems increase the production cost as there is a need for regular additions of fresh solvent and implementation of processes for effluent treatment to cope with increasingly stringent environmental regulations
