ABSTRACT:
A flotation process for concentrating tungsten or tin ores is achieved by grinding the ores with a grinding medium other than steel, first conditioning a deslimed sulfide free pulp with an acid, further treating the pulp with an emulsified collector and recovering the tungsten or tin in the float. The flotation concentrate can be further enriched by leaching with an inorganic acid.
