中国南方风化磷块岩中的风化磷矿的自然类型可分为两类七种型式,其中以“原位面型风化磷矿”和“位移溶洞砂砾磷矿”为主。风化磷矿是由其原矿的自身特性与外部适宜条件(水文地质条件为主导)综合作用的产物。根据碳酸盐、磷酸盐矿物分解、淋失程度可划分为弱风化、风化、强风化三个阶段。可用直接法、间接法和数学法3类共13种方法加以判别
The natural types of weathered phosphate rock in weathered phosphogypsum in southern China can be divided into two types and seven types, of which “in situ type weathered phosphate rock” and “displaced karst gravel phosphate rock” are the main types. Weathered phosphate rock is a product of the combined effect of its own ore properties and external suitability conditions (hydrogeological conditions dominated). According to carbonate, phosphate mineral decomposition, leaching degree can be divided into weak weathering, weathering, strong weathering three stages. Can be used direct method, indirect method and mathematical method of a total of 13 kinds of methods to be discriminated
