Yichang, Hubei Province, Shennongjia Baokang area and phosphorus mineral deposition type metal phosphate rock, was aphanitic block, false oolite granular aggregates, i.e. phosphate rock, is hard mineral stone. Deposit: divided into three ore-forming layers, of which the lower layer is a mineral layer of industrial value. The lower ore layer is divided into three ore layers, namely the upper and lower lean ore layers and the Zhongfu deposit, forming a “poor and rich†ore structure. The upper lean layer (Ph13-3) consists of dolomite strips of phosphorite, with an average grade of 18.01%, which is a carbonate type ore. The middle layer (Ph13-2) consists of dense strips of phosphate rock with an average grade of 32.79%. The lower lean layer (Ph13-1) ore is composed of argillaceous strips of phosphate rock with an average grade of 15.16% and is a silicate type ore. The entire Ph13 deposit is a mixed ore. There are few rich ore in the area, and there are a lot of ore. The chemical composition of the ore in Yichang and Baokang mines is listed below (Table 1).
