INORGANIC PERBROMIDE COMPOSITIONS AND METHODS FOR USE¹THEREOF

摘要

This invention relates to compositions for the hydrometallurgical recovery of precious metals, and the use of certain of such compositions in other applications. The composition comprises: water, at least about 25 % by weight bromine, between about 4 % and about 30 % by weight hydrobromic acid, and between about 4 % and about 15 % by weight of a metal bromine. The composition comprising a molar excess of bromide ion over bromine of at least about 30 %. The composition has a pH of not greater than about 1.0.
