Abstract

Oppfinnelsen angår blandinger for hydrometallurgisk utvinning av edel- metaller og anvendelse av visse av slike blandinger for andre anvendelser. Blandingen omfatter: vann, minst 25 vekt% brom, mellom 4 vekt% og 30 vekt% hydrobromsyre og mellom 4 vekt% og 25 vekt% av et metallbrom- id. Blandingen omfatter et molart over- skudd av bromidion i forhold til brom på minst 30%. Blandingen har pH på ikke større enn 1,0.The invention relates to compositions for the hydrometallurgical extraction of precious metals and the use of certain of such compositions for other applications. The mixture comprises: water, at least 25% by weight bromine, between 4% by weight and 30% by weight hydrobromic acid, and between 4% by weight and 25% by weight of a metal bromide. The mixture comprises a molar excess of bromide ion relative to bromine of at least 30%. The mixture has a pH of not greater than 1.0.
