Consequently, early potash producers struggled to adjust their techniques to meet growing demands, though in 1790, the first U.S. patent was issued for an improved potash process. Despite efforts at advancement, these early potash production methods were unable to generate sufficient amounts of quality potash to meet global needs.

The plant operates under ambient conditions without the need for steam (which is used in the old hot leach plant). The plant is built of carbon steel because the ambient process temperature eliminates the need for noble metals such as inconel, monel, or titanium, which makes the CCP plant operating cost much lower than the hot plant.

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.
