Introduction
Polyhalite is a complex salt mineral that can be used as a fertilizer. It contains calcium, potassium sulfates, and magnesium. The main purpose of the beneficiation is to gain potassium from the polyhalite because potassium is the nutrient for the plants.
The beds of the polyhalite are in England majorly. In Turkey, it will be worked in Ankara. The studies of polyhalite are so rare around the world. Hence, the numerical part of the study is not included in this report because it is confidential (ICL Innovation, 2021). Some of the properties of the polyhalite are as in the table .

About the Experiment
In the experiment, leaching experiments are done on the sample, which consists of polyhalite. Some parameters are kept constant to see the most effective way, and some are changed, such as particle sizes, solid-liquid proportions, and stirring durations. Because no heating process would be done, mechanical agitation machines are used.
Then, filtration is done to drain the water mixed with the sample. Vacuum filtration with air compressor equipment is used. When the water is removed, samples are put in the furnace for 24 hours to eliminate the moisture.
Dry samples are ground in the mortar for the grade analysis after 24 hours in the furnace. They are packed in small sample bags.
