the first objective of mineral processing and extractive metallurgy is to remove the mineral as soon as freed and as coarse as possible” is the first rule in treating complex ores. ores containing two or three metals have been satisfactorily treated for a number of years. today, however, ores containing as high as four, five and even six and seven minerals are being efficiently concentrated.
my company using ball mill as the second stage of grinding usually experiences high mill mass. we are therefore forced to grind out in order to reduce the mill mass. we also experience excessive overflow of materials/feed entering the ball mill from the feed launder. what could be the causes o
