1.	Amongstthefollowing ,the totalnumber ofores whichmaybeconcentratedbyfrothfloatation process is :haematite,bauxine, galena, copper pyrites, sphalerite,cassiterite, calamine, argentite , chalocite.
Answer» Solution :4 (FOUR, i.e.,GALENA , copperpyrites, sphalerite , CHAL- cocite ).Pleasenote that althoughargentite `(Ag_2 S ) `isa sulphideore,it isnotconcentratedbyfrothfloatation process sinceitssilvercontentislow. It isbetterconcentratedbyleachingwith NACN.
