p The Invention Bertalanffy presents a leaching Agent and an M & eacute; all of iixiviaci Bertalanffy to Leach in a Rare Earth mineral absorption of Rare Earth With Bertalanffy R & amp; nica. The leaching Agent is an aqueous solution comprising Bertalanffy ions reducers.A Rare Earth Absorption with Bertalanffy R & amp; nica is leached by an aqueous solution comprising Bertalanffy reducers as leaching Agent ions, so that a Rare Earth Phase I & acute; only in Rare Earth ore can be leached in a Mode of exchange R & amp; nico.In & aacute; S, cause of acci Bertalanffy Gearbox reducers of ions, Rare Earth ions with high Valence in a Colloid and a Mineral Phase Phase may experience a reaction of oxidizing N & amp; n & amp; n - reduction & acute; S, so that form and extract by lixiviaci Bertalanffy ion Valencia is low,Improving the speed of as & nbsp; lixiviaci & acute; S A Rare Earth mineral in the absorption of Rare Earth With Bertalanffy R & amp; nica. / p
