摘要： The invention relates to a stirred tank reactor for gas-liquid mass transfer in a slurry. The reactor includes a reactor tank (1) having a first volume (V 1 ), a drive shaft (2) that extends vertically in the reactor tank, a motor (3) for rotating the drive shaft (2), a main impeller (4) which is a downward pumping axial flow impeller attached to the drive shaft (2) to create a main flow pattern in the reactor tank, and a gas inlet (5) arranged to supply gas into the reactor tank (1) to be dispersed to the liquid. The reactor includes a mechanical gas sparging apparatus (6) comprising a dispersion chamber (7) having a second volume (V 2 ) which is substantially smaller than the first volume (V 1 ) of the reactor tank (1), the dispersion chamber being arranged coaxial with the drive shaft (2), and the gas inlet (5) being arranged to feed gas into the dispersion chamber (7), and mixing means (8, 9, 10, 11, 12) arranged within the dispersion chamber (7) for mixing the gas into liquid by dispersing the gas to fine bubbles before the bubbles enter the main flow pattern. The mixing power per unit volume inside the dispersion chamber (7) is significantly larger than the mixing power elsewhere in the reactor.

摘要： The invention relates to a method for leaching an ore containing copper and cobalt in a reactor, where the copper and cobalt minerals of the ore are mainly oxidic and partially sulphidic. The copper and cobalt of the ground ore are leached at ambient pressure by means of a solution containing sulphuric acid, the pH of which has been regulated to the region of 0.8 - 3. The temperature has been adjusted at the start or at some stage of leaching to be above 5O0C and a maximum of the boiling point of the solution in order to leach the oxidic and sulphidic part of the ore. Oxygen-containing gas may be used as an aid to leaching.
