In this paper, the ramp arsenic lead mine was coarse leaf or granular aggregates output. Color green yellow to light yellow; cleavage surface glass gloss, fracture surface grease luster; powder yellowish white; translucent. Hv = 95.6kg / mm ~ 2, Mohs hardness 3.2. Nearly complete (011) cleavage. Proportion 7.1417 (pyknometer method), 7.36 (calculated). Biaxial crystal, negative light, optical axis angle 2V = 35-40 °; birefringence low. Chemical analysis results: PbO80.21, CaO0.05, MgO0.007, (Fe, Mn) O0.601, ZnO0.01As_2O_3 12.28, Sb_2O_3 0.048, P_2O_3 0.039, Cl8.05, the sum of 99.45. The calculated chemical formula is (Pb_ (5.92) Fe_ (0.14) ~ (2+) Ca_ (0.01)) _ (6.07) As_ (2.03) O_ (7.09) Cl_ (3.91). Cell parameters α = 10.7936, b = 10.7663, c = 25.5601; Z = 8. The most intense powder diffraction lines are 3.65 (7), 3.19 (5), 2.845 (10), 2.699 (7), 2.06 (5), 1.641 (4), 1.585 (5). The infrared spectrum includes two major absorption bands of 388-605 and 700-842 cm -1 and a secondary absorption band of 255-323 cm -1.
