Amer et al. have reported, the autoclave leaching process for the glauconitic sandstone as an alternate method for extracting potassium over the roast-leach method. By this process, 95% of potassium …
Sedimentary Rocks
Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.. Erosion and weathering include …
