Energy saving way of transfer in soluble form the metals-satellites of platinum

Known ways of transfer the obstinate metals-satellites of platinum to their soluble forms are presented. It is offered to use for this purpose the way of extra oven metalthermic method, based on initiation the self-extending high-temperature synthesis, being accompanied by heat release. Course of this exothermal reaction is accompanied by formation the soluble intermetallic forms of metals-satellites of platinum with iron, restored and warmed to liquid state. Laboratory approbation of the offered way is carried out.
