1. Förfarande för utvinning av koppar och zink ur koppar- och zinkhaltig sulfidmalm, kännetecknat 5 därav, att den maina malmen underkastas en flotationsopera-tion, varvid i ett första flotationssteg (14) floteras ett första kopparkoncentrat, det första kopparkoncentratet mätäs tili ett andra flotationssteg (18) för floterande av ett relativt zinkfritt kopparkoncentrat, den äterstäende 10 malmen frän det första flotationssteget (14) mätäs tili ett tredje flotationssteg (20) för floterande av ett första zinkkoncentrat, den äterstäende malmen frän det tredje flotationssteget (20) mätäs tili ett fjärde flotationssteg (22) för floterande av ett koppar- och zinkhaltigt material, 15 att ett mellankoncentrat innehällande cirka 5 - 25 % koppar och cirka 2 - 25 % zink, och totalt minst cirka 12 % koppar och zink framställs genom att väljä ätmistone den äterstäende malmen frän det andra flotationssteget (18), och att ett sinkkoncentrat innehällande minst cirka 20 % 20 zink framställs genom att väljä ätminstone en del av det första zinkkoncentratet.
2. Förfarande enligt patentkravet 1, kännetecknat därav, att det första zinkkoncentratet mätäs tili ett femte flotationssteg (24) för floterande av ett 25 ytterligare zinkkoncentrat, att mellankoncentratet framställs genom att kombinera den äterstäende malmen frän det andra flotationssteget (18) med den äterstäende malmen frän det femte flotationssteget (24), och att zinkkoncentratet framställs genom att kombinera det ytterligare zinkkoncent-30 ratet med det koppar- och zinkhaltiga materialet.
3. Förfarande enligt patentkravet 1, kännetecknat därav, att mellankoncentratet bestär av den äterstäende malmen frän det andra flotationssteget (118), och att koncentratet framställs genom att kombinera det 35 första zinkkoncentratet med det koppar- och zinkhaltiga materialet .
