Leaching of lowgrade manganese ores by using nitric. Although the amount of iron in the ore is significantly lower than manganese (Table 2), its low extraction (b0.04% or b0.005 g/L Fe) is depressed by using nitric acid instead of sulphuric acid (see Section 3.2.5).According to these first two factorial designs results, in subsequent tests the acid …
