经重新鉴定, 确认湘潭锰矿床中大量产出锰钾矿(KxMn8-xO16). 其胶体沉积成因的单斜晶系锰钾矿中MnO2含量在90%以上, K2O含量大于3%, 含水量为2.2%~3.1%, 类似于沸石含水量. 其晶胞常数a0 = 0.9974 nm, b0 = 0.2863 nm, c0 = 0.9693 nm, b = 91.47. 由[MnO6]八面体双链构成较大的假四方孔道孔径为0.462 nm×0.466 nm, 并由K+充填在其中. 锰钾矿中大多数锰为Mn4+, 少量Mn3+替代Mn4+与孔道中K+离子数相匹配. 这不仅改变了近一个世纪对于该锰矿床氧化型矿石矿物组成的认识, 更重要的是在自然界中发现了丰富的活性八面体分子筛(OMS-2)的矿物资源.
After re-evaluation, a large amount of Mn-K (Mn) O (x + y) is produced in the Xiangtan manganese ore deposit, and the monoclinic cryptomelane MnO content is above 90% and the K2O content is more than 3% 2.2% ~ 3.1%, similar to the zeolite water content.The lattice constants a0 = 0.9974 nm, b0 = 0.2863 nm, c0 = 0.9693 nm, b = 91.47. The pore diameter is 0.462 nm × 0.466 nm, and is filled in by K + .Mn Mn in Mn-Mn ore is Mn4 +, a small amount of Mn3 + is substituted for Mn4 + to match the number of K + ions in the pore, which not only changes the oxidation of the manganese ore in the past century Type ore mineral composition, more importantly, found in nature, a rich active octahedral molecular sieve (OMS-2) mineral resources.
