New technology development for potassium chloride by flotation: MONOGRAPHY - Softcover

Inhaltsangabe

Based on the scientific research conducted on the thermal enrichment of sylvinite from the Tubegatan deposit, the following conclusions can be drawn:A chemical analysis of sylvinite from the Tubegatan deposit was performed and it was found that it contains the following substances (%): KCl- 31.93; NaCl – 61.37; MgCl2 -0.51; CaSO4 – 1.25; H.O -3.25; Water – 1.69. At a sylvinite firing temperature of 200-6000C, the amount of substances practically does not change compared to the initial sylvinite. As the firing temperature increases from 2000C to 4000C, the amount of substances increases. This is because the physical and chemical moisture in the sylvinite is completely removed. The amount of potassium chloride in the ore increases from 31.93 to 32.57%. Based on the results obtained, the temperature of 4000C can be considered optimal.
