Abstract Silver metal was recovered from spent photography solutions containing up to 10.2 kg/m 3 silver by different techniques including alkaline, acidic and hydrogen peroxide treatments. The acidic process was found to be the most promising. In this process, spent solutions were acidified to pH 3.6 at which precipitation of an insoluble silver sludge was initiated. Silver metal was produced from this silver sludge by thermal decomposition at 980°C. The obtained metal was pure (99.8% silver by mass) and at low cost due to simple technique and the high yield of silver.
