The carnallite process is different from potash, Carnallite cannot be mined and processed Use conventional methods.Solution mining Solution mining in situ leaching (ISL), also known as in situ recovery (ISR) or solution mining, is a recover Minerals such as copper and uranium are passed in situ through boreholes drilled into the deposit. In situ leaching works by artificially dissolving naturally occurring minerals in the solid state. https://en.wikipedia.org › Wiki › In_situ_leach

In situ leaching – Wikipedia

Must be used instead. Solution mining involves drilling holes in the ore body and pumping hot water into the deposit.

How to extract potassium chloride from carnallite?

The process of diluting carnallite is the most widely used method, resulting in a solution Heated to 105 °C in an evaporator, then cooled in a crystallizer to Production of potassium chloride salt. Several patents have been registered for this process.

How is carnallite formed?

Carnallite is named after Prussian mining engineer Rudolph von Carnall.it is formed in Marine evaporite deposits, where seawater is concentrated and evaporated over a long period of time.

Where is carnallite found?

Carnallite occurs along with other chloride minerals in the upper layers of sea salt deposits, where it appears to be an alteration product of pre-existing salt.The mineral is mainly found in Salt deposits in northern Germany; as well as Spain, Tunisia and the American Southwest.
