Then, i found a source of kno3, and now i need your help to purify it. The fertilizer is a composition of 32% of nitrogen and 1% of potassium oxide. The rest of the composition i think that are impurities.
Have you some ideas of how can i extract pure kno3 from this? For 1 kilo of this fertilizer, how much kno3 could i get?
Below, somos photos of the fertilizer called "salitre", in english, "salpeter"
