Yes. It is open as closed would cause bad stuff. I was assuming Mn metal. First you have to oxidize the Mn. Then you oxidize the oxide. So that is Mn + 2KNO3 to get MnO2 +2KNO2. Add your KNO3 and 2 KOH to that? You get 3KNO3 for (54)Mn (306)nitre and (114) KOH. So I guess you might need a lot more nitre although the 2KNO2 might work to make potassium manganate by itself with the addition of 1KOH instead of the extra nitre and added KOH. Assume the hydrogen is imbalanced unless you want to add one nitre to oxidize it. I don't think in this case hydrogen will cause any trouble. You can even get Mg3N2 at high temperature but the borax and metal present should steal the nitrogen. Also the MnO2 becomes MnO.Mn2O3 at high temps too. This makes its oxidation different. For most high temp melts you assume lower oxides like MnO and FeO. What happens in most melts is these metals make complex iron silicates. Here I assumed you might try to make a insoluble hydoxide slag of nickel by adding NaOH and leave the silica out. Nickel OH is not water soluble but K manganate is. It might not be a good fluid slag.
