In order to establish a basic information for various trials concerned with utilization of pyrite, the elemental properties of this mineral are reviewed.In an initial chapter, general characteristics of pyrites are outlined. Subsequently, the results of studies having been carried out hitherto, by many investigators, are summarized with respect to the following subjects in relation to the imperfection of the crystals.1) Chemical composition, 2) Minor elements, 3) Crystallographic property (Lattice constant), 4) Electrical property, 5) Optical property, and6) Oxidation property.

In this study, the extent of variation of the floatability of pyrites in xanthate flotation was measured. Relation between the floatability and crystallographic property, thermoelectric potential, and oxidation property were also investigated.The main results obtained are as follows:(1) The variation of about 30 percent in flotation recovery was recognized under the experimental condition used in this study.(2) The floatability increases with a decrease of the interplanar spacing, absolute value of the thermoelectric potential, and the oxidation rate. But, these relations containing some exceptional data.(3) Besides, “Relation between Floatability with Xanthate and Natural Floatabiliiy”, “Effect of Oxldation on Flotation Recovery” and “Effect of Activation with Copper Sulphate” were also discussed.
