滇池地区渔户村磷矿是云南富磷矿床之一。矿层产于下寒武统渔户村组中谊村段,呈缓倾斜层状产出。含矿岩系自上而下划分为上富矿(K_3)、上夹层(J_2)、上贫矿(K_2)、下夹层(J_1)、下矿层(K_1)及过渡层(K_1′)六层。 矿床风化带发育,风化带K_3平均厚5.43米,P_2O_5平均30.2％;上夹层平均厚3.72米,P_2O_5平均11.88％;K_2平均厚6.5米,P_2O_5平均16.55％;下夹层平均厚7.35米,P_2O_5平均7.44％;K_1平均厚7.45米、P_2O_5平均26.99％;过渡层平均厚1.49米,P_2O_5平均17.18％。 云南过去圈定矿体时多采用边界品位8％、工业品位15％,工业矿石中再划分为Ⅰ、
Phosphate rock from Fishermen’s Village in Dianchi Lake area is one of Yunnan-rich phosphate deposits. The ore is produced in the middle Yiyi section of the Lower Cambrian Fishery Group, with a gently inclined layered output. The ore-bearing rocks are divided into six layers, namely, the upper orebody (K_3), the upper sandstone (J_2), the lean ore mine (K_2), the lower sandstone (J_1), the lower ore rock (K_1) and the transitional layer (K_1 ’) from top to bottom. The weathering belt developed with an average thickness of 5.43 m and average P_2O_5 of 30.2%. The average thickness of the upper interlayer was 3.72 m and the average of P_2O_5 was 11.88%. The average thickness of K_2 was 6.5 m and the average of P_2O_5 was 16.55% 7.44%. K_1 average thickness is 7.45 meters and P_2O_5 average is 26.99%. The average thickness of transitional layer is 1.49 meters and P_2O_5 is 17.18% on average. In the past, Yunnan delineated the ore body to use more than 8% of the boundary grade and 15% of the industrial grade. The industrial ore was further divided into Ⅰ,
