After cooling down, all of the particles were resieved to 125–300 μm. For every 50 g of manganese ore, solid Cu(NO 3) 2 ·3H 2 O (3.8 g) was used as a precursor and was dissolved in water (15 ml) to give the solution. The composition of the manganese ore was analyzed by X-ray fluorescence (XRF) and summarized in Table 1. The BET …
