摘　　要：给出了吸附沉淀百分数的定义。用ICP—AES法测量了Al^(3+)、Fe^(3+)、Ca^(2+)、Mg^(2+)4种金属离子在红柱石—十二烷基磺酸钠体系中的吸附沉淀百分数,考查了它们对红柱石可浮性的影响。认为吸附沉淀百分数PAP代表了金属离子对矿物的活化能力,PAP越大,活化能力越强;PAP小到一定程度,金属离子对矿物的浮选起抑制作用。In this paper. the defination of the percentage of adsorptive precipitation(PAP) is given. The PAP of Al^(3+). Fe^(3+). Ca^(2+) and Mg^(2+) ions in flotation pulp is measured by ICP—AES. The authors have investigated the influence of mhe metal ions on flotability of andalusite, concluding that the PAP of metal ions can represent their activative power. and the bigger the PAP. the stronger their activetive power. However. When the PAP is small to a certain extent, the 4 metal ions have depressing effect on minerals in flotation.
