The wet process is the common treatment for the production of phosphate fertilizers and the production of technical phosphoric acid. About 95% of all the phosphoric acid is produced through the wet process, since this is the route toward readily available phosphorus-based fertilizers (Schrödter et al. 2008). In this process, strong …

Alkali metal fluosilicate is used as an intermediate reactant in a process for the production of hydrochloric acid and an alkali metal sulfate from sulfuric acid and an alkali metal chloride. The process includes the reaction of alkali metal fluosilicate with sulfuric acid to produce alkali metal sulfate and H2 SiF6, the latter being reacted with alkali metal …
By adding magnesium salts to potassium sulfate, a granular potassium-magnesium compound fertilizer can also be produced. Potassium is the third major plant and crop nutrient after nitrogen and phosphorus. Potash is the common name for various mined and manufactured salts that contain potassium.
Potassium concentration had no significant effect on ethanol and glycerol yields. The presence of trace metals significantly increased the chitosan yield at an optimal phosphate and potassium concentration (0.50 g/g cell wall). By contrast, production of ethanol by the fungus was negatively affected (0.33 g/g sugars).
Most of the potassium salts are commonly mined in the northern hemisphere due to the availability of soluble potash ores like sylvinite, which is a mixture of sylvite and halite. 2,3 Canada tops the chart of both the world potash reserve with 26% of total reserve and world leading producer with 28% of total production followed by Russia ...

The vegetative growth of rice plants (plant height and number of tillers) during the first 40 days of incubation in the microcosms was more pronounced in the potassium phosphate-fertilized than in the unfertilized microcosms (Fig. 1).Pore water concentrations of phosphate reached a maximum at 25–40 days after planting and were higher (10–24 …
Phosphates, compounds of the element phosphorus, are produced from relatively abundant supplies of phosphate rock. The major use of phosphate is to supply phosphorus, one of the three essential plant foods—nitrogen, phosphorus, and potassium. Phosphate rock extraction from its ore, and its subsequent conversion into fertilizer …
