The potash concentration in the leach solution in a single stage leaching is about 10–11 g/L, which was increased to about 40 g/L by four times recycling of the leach liquor. The leach liquor was further treated for removal of impurity elements and recovery of potassium as sulfate (Sulfate of potash, SOP) for fertilizer application.

The very first patent in the US is potash. It was first patented in 1790 and it still remains an essential product today. Potash is primarily used as an agricultural fertilizer and this is mainly because it is a great source of soluble potassium.This potassium is one of the main plant macronutrients alongside nitrogen and phosphorus (i.e. NPK).
