Abstract: A method for leaching a sulfidic metal concentrate in hydrometallurgical production of metal in a leaching process from which hot water vapor containing off-gas is conducted out and to which an acid solution warmed up to an elevated temperature is conducted. The acid solution is warmed up to an elevated temperature by bringing off-gas of the leaching step into direct contact with the acid solution.
Abstract translation: 在浸出过程中浸出硫化金属浓缩物浸出金属浓缩物的方法，其中进行含有废气的热水蒸气并将酸溶液加热至高温。 通过使浸出步骤的废气与酸溶液直接接触将酸溶液升温至升高的温度。
