The results showed that compared with traditional fluorite and phosphorous slag, phosphorous slag composite mineralizer was effective on reducing amount of f-CaO in cement clinker and improving burnablity of raw meals, but the effect was still obvious when sintering temperature and sintering time were increasing. The analysis of XRD, SEM and petrographic structure showed that phosphorous slag composite mineralizer decreased viscosity of liquid, promotes the formation of Alite in clinker and improves crystal form and size of minerals.

Chemical analyses of ores sampled from different elevation at the representative Zoujiashan uranium deposit indicate that Fe〓O〓, FeO, MgO and P〓O〓 increase evidently with depth which is related to alteration of haematite, chlorite and apatite, Na〓O and Na〓O+ K〓O also increase with depth, reaching a maximum of Na〓O at 911 meters below the surface, which suggests alkaline alteration increases downwards. At depth of 90 meters below sea level, where the boundary of the two cycles of the volcanic rocks is located, CaO reaches the maximum, representing maximum of alteration of fluorite.
