<p>Employing only a short time for heating-up and leaching of max. 30 min. the ground Cu ores or Cu-contg. extraction byproducts are leached in a tubular reactor at 100-125 degrees C, and at a controlled pressure, so that boiling of the suspension in the reactor will not occur. The time for heating up, leaching and cooling is adjusted to take is not >15 min., pref. max. 10 min., and leaching time alone at the max. temp. is not >1 min.</p> |
