Arsenopyrite removal from pyrite concentrate using pulsating high gradient magnetic separation
Results in Physics, 2018 Pyrite concentrate has been the mineral resource for sulfur acid production in China, and arsenopyrite as one of the arsenic-containing minerals, was usually found in the pyrite ores, resulting in the serious environmental problems in the production ...
