| description | The invention discloses a method for harmlessly recovering copper and germanium from a high-iron and high-copper solution, which comprises the following steps: carrying out secondary low-acid leaching on slag obtained by primary neutral leaching of zinc hydrometallurgy roasted ore, carrying out third-time high-temperature and high-acid leaching on slag obtained by solid-solid separation of the secondary low-acid leaching solution to recover valuable metals zinc, copper and germanium, and producing lead-silver concentrate for sale, the solution obtained after three times of high-temperature and high-acid leaching contains sulfuric acid, iron, copper, zinc and germanium, the iron is mainly ferric iron, and the solution is the high-iron and high-copper solution. According to the method, acid neutralization and ferric iron reduction are completed in one step, selective reduction, replacement and separation of copper and germanium are achieved, the valuable metal recovery rate is high, and the cost is low.
