Although the ball-milling method has been widely used to exfoliate the bulk layered materials into 2D materials, it is rarely used to prepare air-sensitive species, such as black phosphorous and Bi.33 The high energy and large force would lead to the oxidation of the as-prepared nanomaterials even with a trace amount of oxygen inside.+
With an increase of ballmilling time, superior electrochemical reactivity is imparted owing to enlarged active area and increased catalytic ability. The obtained graphene nanosheets are sensitive for electrochemical oxidation of phenols e.g., hydroquinone, p chlorophenol, and p nitrophenol, and thus qualified for the simultaneous sensing of trace level of phenols.+
The crushed metalized kiln slag is entering into Ball mill for grinding, and then entering into two-stage magnetic separators for separation, of which, one is for roughing 1800-2000GS, the other is for cleaning 1000-1200GS, then get final Fe concentrate 55-60 up. The tails will be pumped into GHM Specially-designed Tails Dewatering Machine.+
