    Abstract: A method for leaching a sulfidic metal concentrate in hydrometallurgical production of metal in a leaching process from which hot water vapor containing off-gas is conducted out and to which an acid solution warmed up to an elevated temperature is conducted. The acid solution is warmed up to an elevated temperature by bringing off-gas of the leaching step into direct contact with the acid solution.

    Abstract: The invention relates to a method of using a flotation machine that is used in metallurgical processes and to a flotation machine. The flotation machine foams hydrophobic particles from an aqueous slurry that contains these particles. The flotation machine includes a flotation cell (1), and a rotor (2) that is inside the flotation cell. The rotor (2) is rotated at a mixing power, which maintains the suspension in the slurry and mixing of air with the slurry to form the foam, and the mixing power is controlled by adjusting the rotation speed of the rotor. The amount of solid matter S accumulated on the bottom of the cell (1) is determined, and the rotation speed of the rotor (2) is adjusted on the basis of the determined amount of solid matter. The flotation machine includes a measuring device (5) for determining the amount of solid matter accumulated on the bottom of the cell. The adjusting device (4) is arranged to adjust the rotation speed of the motor (3), which rotates the rotor (2), on the basis of the measuring result of the measuring device (5) to remove the solid matter from the bottom of the cell.

    Abstract: A TSL lance has an outer shell of three substantially concentric lance pipes, at least one further lance pipe concentrically within the shell, and an annular end wall at an outlet end of the lance which joins ends of outermost and innermost lance pipes of the shell at an outlet end of the lance and is spaced from an outlet end of the intermediate lance pipe of the shell. Coolant fluid is able to be circulated through the shell, by flow to and away from the outlet end. The spacing between the end wall and the outlet end of the intermediate pipe provides a constriction to the flow of coolant fluid to increase coolant fluid flow velocity therebetween. The further lance pipe defines a central bore and is spaced from the innermost lance pipe of the shell to define an annular passage, whereby materials passing along the bore and the passage mix adjacent to the outlet end of the lance. The end wall and an adjacent minor part of the length of the shell comprise a replaceable lance tip assembly.
