Abstract: Tests were made on four processes to pre-concentration for discarding waste for 50~20 mm, 20~2 mm and 2~0.5 mm ore size fractions of Meishan Iron Mine, where 0.5~0 mm went directly to magnetic separation and the magnetic separation concentrate joined the final iron concentrate.  The optimal one achieued with the iron concentrate grade and recovery being 57.21% and 75.64% respectively.
