potash extraction process

Extraction of potash from cocoa pod husks -

1985-1-1  Extraction of potash from the cocoa pod ash Ten grams of the ash from the incinerator was soaked in 200 ml H20, stirred vigorously and left to stand for 24h. The clear solution was decanted and filtered through a column packed with glass wool and asbestos powder. The filtrate was evaporated to dryness in an oven at 105.

[PDF] EXTRACTION OF POTASH FROM K-FELDSPAR

The recov ery of potash is found to be 35% in the case of H 2SO4 medium. In hydrothermal process, maximum recovery of potash is attained as 71% in H 2SO4 medium by repeated cycles of leaching. Molten salt extraction was performed at 850°C using MgCl2 and CaCl 2 as molten leaching media. The duration of digestion was about 8 hours.
