Abstract: The invention relates to a method for recovering metals from oxidic ores by hydrometallurgical methods. In the method, the oxidic ore is contacted with water under conditions in which the metal is released from the ore in water, and the metal is recovered from the solution thus obtained by precipitating with a boron compound.
