黄磷副产磷铁国外产量很大,如美国近几年年产量都在10万吨以上。我国由于条件不同,回收利用有限。本文就收集到的资料和生产试验情况综述如下。制磷所用磷灰石矿中的含铁量是决定副 Phosphorus and phosphorus phosphorus by-product of foreign production is very large, such as the United States in recent years, annual output of 100,000 tons or more. Due to different conditions in our country, recycling is limited. This article on the collected information and production test situation are summarized below. The amount of iron in apatite mines used for making phosphorus is the deciding factor
