2015-1-10 The mechanical activation of pyrite was conducted in a planetary ball mill (Pulverisette 6, FRITSCH, Germany) with a rotation speed of 400 rpm under argon atmosphere to prevent possible chemical reaction. 15 stainless steel balls with a diameter of 20 mm were used for milling by a ball to powder weight ratio of 20:1.The samples were mechanically activated for 20, 50 and 100 min.
