Flotation Separation of Calcite from Apatite Using AADPA-12 as a Collector and its Mechanism

摘要：

The flotation performance of alkyl amine dimethyl phosphonic acid (AADPA-12) on calcite and its mechanism were studied by flotation test and infrared spectrometry (IR) as well as adsorption strength test for separating calcite from apatite by flotation. The results show that calcite and apatite can be separated when using AADPA-12 and aluminum sulfate as a collector and a regulator, respectively. AADPA12 can be absorbed on the surface of calcite by chemical and physical reaction.
