titleOfInvention |
A method for the electrolytic recovery of antimony, mercury, arsenic and/or tin |
abstract |
The invention relates to a method for selectively leaching at least one of the elements antimony, mercury, arsenic and tin from sulphidic and oxidic materials with alkali sulphide solutions and subsequent electrolytic recovery of the leached elements. The method consists of maintaining the sulphide ion concentration in mol/l multiplied by two and the hydroxyl ion concentration in mol/l at a value of at least 8 and that the quantity of hydroxyl ions is at least in a quantity equimolar to the quantity of sulphide ions. The electrolyses must be effected at an anode current density of more than 1500 A/m2. |
