Get MoreAll plants, especially cocoa and oil palm, require magnesium (Mg) along with other macro- and micro-nutrients. Kieserite as the most common Mg-supplying fertilizer for crops is still imported for Indonesia due to lack of natural deposits in the country. On the other hand, dolomites (CaMgCO3) are found abundantly and mostly used as material due to low MgO content and …

Get MoreThe technology process usually takes place in shaft or rotary kilns, where the dolomite stone, CaMg(CO3)2, is subjected to a high temperature heat treatment. The calcination of the dolomite is highly endothermic reaction, requiring significant amount of thermal energy to produce sintered dolomite (CaO, MgO), generating a large flow of hot gases ...
Get MoreThe silicothermic process is based on the reaction of silica with carbon to give silicon metal which is subsequently used to produce magnesium by reaction with calcined dolomite. The Pidgeon and Magnetherm processes employ this procedure. The Pidgeon process is a batch process in which dolime and silicon are sized, briquetted, and cha rged into ...
Get MoreKieserite is primarily obtained from deep underground deposits of minerals The ore is brought to the surface where the magnesium salts are separated from potassium and sodium salts using a unique, dry electrostatic (ESTA) process.
Get MoreThis paper describes the principles of the process, developments carried out to improve the Uhde Pugmill process and its product quality making it an attractive, well-proven and reliable choice for the modern fertiliser industry. Uhde's technology is based on over 50 years of experience in the designing of neutralisation and granulation plants.
Get Morevariation of the Dow process. In this process lime is used to precipitate magnesium hydroxide from the water; the precipitate is dissolved in hydrochloric acid and mag nesium chloride is produced; the magnesium chloride is decomposed in an electrolytic cell into magnesium and chlorine. It is now common practice to substitute dolomite for lime.
Get MoreThe performance of CaO/Natural Dolomite catalyst was examined in a batch reactor for transesterification reaction of coconut oil with methanol. From the experiments, the optimum process conditions were achieved at a 60°C of reaction temperature, a 5 wt.% of catalyst amount, and 6 : 1 of methanol to coconut oil mass ratio.
Get More• The type of manufacturing process used can also affect the product properties, e.g. materials made by the nitrophosphate process may behave differently from those made by the mixed acid phosphate route. • Calcium sulphate as listed does not cover impure by-product gypsum. • Limestone and dolomite generally refer to mined material.
