| 摘要 |
The invention relates to the extraction of metal, particularly precious metals, from corresponding ore material, in which starting ore material is comminuted in a material bed roll mill, then deposited on a heap and leached by the addition of leaching fluid. In order that the metal can be extracted with a particularly high rate of yield from the starting ore material, the comminuted ore material is deposited on the heap with a maximum grain size of approximately 12 to 15 mm.
