Method for refining concentrate containing precious metals

The invention relates to a method for refining precious metal concentrate, and according to said method, at least the precious metal concentrate ( 9 ), reaction gas ( 10 ), flux ( 11 ) and flue dust ( 12 ) to be treated are fed together into the reacton shaft ( 3 ) of a suspension smelting furnace ( 1 ); in the suspension smelting furnace, there are created separate phases, matte ( 8 ) and slag ( 7 ); and the slag created in the suspension smelting furnace is conducted into an electric furnace ( 2 ), so that there is created metallicized matte ( 14 ) and waste slag ( 13 ). Thereafter the matte ( 8 ) from the suspension smelting furnace is conducted to hydrometallurgical treatment ( 15 ), and the slag conducted into the electric furnace is treated together with a reducing agent and possibly with a material lowering the melting point or improving fluidity, and the obtained metallicized matte ( 14 ) is conducted either to hydrometallurgical treatment ( 16 ) or back into the suspension smelting furnace in ( 1 ).
