The ash content of dry cocoa husks, a non-utilized component of the cocoa pod, was found to be 8·2% and the average potassium content (determined as potash) of the ash was found to be 43·5%. The efficiency of an incinerator specially built for the ashing, relative to a muffle furnace, was 98·6%. 2020-6-30 Complete extraction of potassium was achieved by roasting feldspar with eggshell powder and 1.5 times the stoichiometric amount of hydrochloric acid. The optimized conditions were feldspar to ESP in a ratio of 1:1.8 at 900 °C for 30 min followed by leaching with water. 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 . Thesis (B.S.)--Armour Institute of Technology, 1919 Bibliography: leaf 30 B.S. in Chemical Engineering, 1919 2016-12-11 Potash is a mixture of chemicals, and is obtained by drying the liquor which results from leaching wood ashes in water (2). The raw potash we will extract in this article, shown to the right, contains a mixture of potassium and sodium carbonates and potassium and sodium chlorides, plus some other minor constituents. 2020-7-14 Figure 2 presents the dependence of potassium extraction on the salt to ore mass ratios and reaction time for different values of temperature where the salt mixture is in a liquid phase at the eutectic composition (32 wt % NaCl and 68 wt % CaCl 2). As shown, potassium extraction strongly increases with an increase in the reaction temperature. Weigh 12.5g of potassium sulfate and dissolved in a minimum quantity of distilled water in a beaker. Stir to dissolve the crystals. Take a conical flask, in that dissolve 50g of
