The invention relates to compositions for the recovery of precious metals in hydrometallurgy, and to the use of some of these compositions in other applications. The composition comprises: water, at least 25% by weight of bromine, between approximately 4 and approximately 30%, by weight, of hydrobromic acid and between approximately 4 and approximately 15%, by weight, of bromide in metallic form . The composition has an excess of mass of bromide ions with respect to bromine of at least about 30%. The composition has a pH of not more than about 1.0. |
