Crystallization and separation of KCl from carnallite ore: Process development, simulation, and economic feasibility
Given an increasing demand for potassium in Brazil, the mining and use of carnallite is becoming increasingly important, because the current source of potassium (sylvinite) is being depleted and there is a risk of shortages. Based on theoretical and practical data available in the literatur...

description |
Given an increasing demand for potassium in Brazil, the mining and use of
carnallite is becoming increasingly important, because the current source of
potassium (sylvinite) is being depleted and there is a risk of shortages.
Based on theoretical and practical data available in the literature, this
work describes the development, simulation, and economic feasibility of a
process for dissolution and crystallization of potassium chloride from
carnallite ore. Positive results were obtained following application of the
Hoffman diagram and determination of the corresponding equation. The proposed
process provided over 85% potassium chloride crystallization, demonstrating
its superior performance, compared to existing procedures. |
