| titleOfInvention | A method for enriching and co-producing light calcium carbonate and magnesium hydroxide with high-magnesium phosphorus tailings |
| abstract | A method for co-producing magnesium hydroxide and light calcium carbonate from magnesium-rich phosphorus tailings, calcining the high-magnesium phosphorus tailings to form calcined phosphorus tailings powder, and then using the calcined phosphorus tailings powder as a raw material to pass hot water Digestion reaction and secondary ammonium salt leaching fully separate calcium hydroxide, use leaching liquid to carbonize to produce light calcium carbonate, and carbonize filter residue to separate magnesium hydroxide; Extraction, carbonization of leaching solution, carbonization of leaching filter residue, ammoniation and other process steps are used to co-produce high-purity magnesium hydroxide, as well as food-grade light calcium carbonate and phosphorus concentrate powder with a P 2 O 5 content of more than 30%. The invention not only solves the problem of enriching low-grade phosphate tailing powder into high-grade phosphate ore concentrate, but also prepares high value-added magnesium hydroxide and food-grade light calcium carbonate. The goal of circular economy is to "recover waste from waste" and change "waste" into resources, which has good environmental and social benefits. |
