Webb28 maj 2024 · In pyrometallurgical processes refining copper, the main source of loss in the conversion stage is from slag. This paper reports on research work treating converter slag containing high percentages of copper (36 wt%) using ammonium hydroxide at room temperature. Variables analyzed are solution pH, agitation, temperature, NH4OH … In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH + 4] = 0.0042 M, [OH −] = 0.0042 M, [NH 3] = 0.9958 M, and pH = 14 + log 10 [OH −] = 11.62. The base ionization constant is K b = [NH + 4][OH −] / [NH 3] = 1.77 × 10 −5.
