Abstract: The invention relates to a method of operating a zinc-bromine battery, especially at a high temperature, comprising adding 1-n-butyl-2-methyl-pyridinium bromide to the electrolyte of said battery, and charging or discharging said cell. Also provided is the use of 1-n-butyl-2-methyl-pyridinium bromide as an additive in a zinc-bromine battery operating at a temperature above 30° C., and an aqueous concentrate with high content of 1-n-butyl-2-methyl-pyridinium bromide.

Abstract: A process for recovering gold from a refractory gold ore, comprising the steps of: electrolyzing a mixture consisting of the ore particles and an aqueous bromide solution in an electrolytic cell having anode and cathode, wherein bromine is produced at the anode by oxidation of the bromide, thereby dissolving gold in the aqueous phase; separating the ore particles from the aqueous phase to obtain a leach liquor; adjusting the pH of the leach liquor to the alkaline range to produce a gold-containing precipitate; collecting the gold-containing precipitate and recycling a bromide-containing barren solution for reuse as an aqueous bromide feed solution.
