| Overview | potassium Petrochemistry is divided into KCl, Crystal is an equiaxed halide mineral, also known as potassium salt. Pure potassium salt colorless transparent or white, containing impurities can be dyed red, yellow, blue and other colors, heat transmission radiation performance is good. |
| presence | The potash is usually produced in a dense granular form, and the distribution is far less than that of the halite. Potash, together with gypsum, is usually produced in salt-bearing sedimentary rocks and in modern sedimentary basins. A small amount of potash salt is found near the craters as a volcanic jet product. |
| uses | the majority of the potash is used in the manufacture of potash, and some of the compounds used in the extraction and manufacture of potassium are the main source of potassium. Large crystals that are colorless and transparent can be used as optical materials. used in the manufacture of glass and ceramics, can also be used to make potassium fertilizer |
| production method | wet decomposition process of potassium feldspar: the potassium feldspar was broken to less than 100 mesh, together with the main reactant inorganic acid and the reaction aid fluoride, the main reactant is continuously put into a stirrer, and the reaction is decomposed at a temperature of 60~100 ℃ under normal pressure. Then, the material is transferred to a separator, and the obtained solid phase is separated into a rotary kiln, the concentrate was obtained after roasting at a furnace temperature of 500 to 750 °c. The gas generated in the calcination is completely absorbed by the absorption tower and then returned to the agitator for recycling, and the separated liquid phase is returned to the agitator for recycling. China is rich in potassium feldspar resources, the use of potassium feldspar potassium fertilizer, the use of sintering method, high temperature melting method, hydrothermal method, blast furnace smelting method, low temperature decomposition method. |
