1. Förfarande för torrseparation av pyrit ur stenkol, i vilket förfarande stenkolen (K) i ett malningssteg under-5 kastas en maltorkning i en malgasström och det krossade mal-godset med malgasströmmen förs tili ett siktsteg (8) och i siktsteget (8) delas i k ena sidän värdefullt,t.ex. bränn-bart fingods och k andra sidan grusgods, varvid ytterligare grusgodset som grusiterging kan äterinföras soin kretslopp 10 i malningssteget (1) och slutligen pyrit (P) avlägsnas ur det finfördelade malgodset, kännetecknat därav, att grusätergängen helt eller delvis uttages ur kretsloppet och förs tili ett täthetssepareringssteg, vilket separerar fr&n varandra k ena sidan en blandning, vilken uppvisar 15 huvudsakligen tung pyrit (P) och närvarande krossat sten-material och k andra sidan ännu det medförda finfördelade kolet (K), och att blandningen av pyrit och krossat sten-material avförs och det finfördelade kolet leds tili vidare användning, t.ex. äter tili malningssteget. 20
2. Förfarande enligt patentkravet 1, känne tecknat därav, att den ur kretsloppet avförda grus-ätergängen för inledandet i täthetssepareringssteget (10) underkastas siktning och därvid befrias frän det grovt krossade kolet (K). 25
3. Förfarande enligt nägot av patentkraven 1 eller 2, kännetecknat därav, att den ur tätningssepa-reringssteget avförda blandningen av pyrit och krossat sten-material underkastas en andra siktning.
4. Utföringsanläggning av förfarandet enligt nägot av 30 patentkraven 1-3, med malningsanordning (1) efterkopplad sikt (8) och anordning för en grusgodsäterföring, varvid i malningsanordningen (1) kan införas malgas (G) och 35 det krossade malgodset med malgasströmmen kan införas i sik-ten (8), väri en separation i värdefullt fingods och grusgods
