In a method and an apparatus for the manufacture of clinker of mineral raw materials, such as cement clinker, according to the wet process and ensuring an almost complete absorption of the SO2-emission in the kiln gases from a kiln, such as a rotary kiln working according to this process, the wet process is converted into a semi-dry process in feeding the wet ground raw materials (6, 7) together with a raw mix component such as flyash (5) and/or precipitated filter dust (18, 20) into gas suspension drying unit (4) mounted-seen in the direction of movement of the kiln gases-after a kiln (1) and heated with kiln gases for creating a gas/material suspension in the drying unit (4) thereby preheating and drying the wet raw materials before their returning via an overflow bin (11) and a duct (14) to the kiln inlet (2) and their further treatment in the kiln (1) and thereby simultaneously through an SO2 adsorption by the dry particles in the unit (4) ensuring the cleansing of the kiln gases.
