chanhen owned large phosphate mine --laohudong phosphate mine located at weng’an county guizhou province, the miningarea is 5.3 square kilometers, the ore body length is 3.8 kilometers, theaverage thickness is 26m, total reserves is 365 million tons, the average gradeis 27%; associated fluorine resource is 6 milliontons, iodineresources is 6200 tons. chanhen plans to build a large-scale mine filed withcapacity 5 million tons / year.
laohudong phosphate mine has advantages such as location, qualityand scale. with the weng'an highway and railway construction and shippingconditions continue to improve, the advantages of laohudong phosphate mine willbe more obvious. with gradually reduction of the average grade of china'sphosphate mining, high grade phosphate rock resource become more valuable; laohudongphosphate mine has good washability, it can make p2o5 content in concentrate at32 - 36%, the recovery rate is more than 92%; good chemical activity,especially suitable for wet process phosphorus chemical industry, to produce avariety of quality phosphate, but also can produce industrial grade and foodgrade phosphoric acid. the distribution of phosphate rock resources in laohudongis concentrated, suitable for large-scale mining with low investment, highefficiency and low cost.
