摘要
以云南低重金属磷矿为原料,按磷矿-磷酸-脱氟剂(AMP)工艺配方制备饲料级脱氟磷酸三钙进行了试验,取得了最佳工艺控制条件。进行了该工艺的适应性试验,证明适宜四川、湖北、贵州的磷矿矿种,所得产品进行了化学分析和X-衍射分析,并与韩国产品进行了对比,达到国外同类产品质量要求。
The research of feed grade calcium phosphate with Yunnan phosphate rock that has lower heavy metal by the formula phosphate rock-phosphoric acid- fluoride-free agent(AMP)has been described. The best condition has been gotten through trials. This formula can suit for different phosphate rock, for example from Sichuan, Hubei, Guizhou province. The chemical and X-diffraction analyses has been made. Our product quality reach the international standard after comparing with the product made in Korea.
