Abstract The gold recovery from secondary resources is in the spotlight due to its high economic value and as the circular economy's main objective. As a valuable secondary source, the slag resulted from the gold-bearing electrolytic mud smelting contains up to 0.8-15 k g t(-1) Au and 9-13 kg t(-1) Ag, respectively. The gravity separation's use to concentrate gold contained by the slag causes significantly reduced reagents and energy consumptions. The diminished reacting time and the increased recovery yield due to the augmentation of contact surface between the solid phase and the leaching reagent are other important advantages. The present contribution aims to point out that a new different type of waste such as the slag resulted from the gold-bearing electrolytic mud smelting may be capitalized using gravity separation on Gemini table and Knelson concentrator, respectively. Metal recoveries up to 90-92% Au and 46-60% Ag, respectively, were obtained on Gemini table. [GRAPHICS] .
