求翻译：Tanabe等[2] 将天然锰矿加热还原成MnO,然后将MnO 转化为锰氨基甲酸铵盐, 后者经加热分解成密度较大的MnCO3,将此MnCO3热分解可以制得粗MnO2。是什么意思？

Such Tanabe [ 2] The natural manganese ore MnO heat, and then restore to MnO will be transformed into manganese amino formic acid ammonium salt, which exploded into the heat with a greater density of MnCO 3, which will be 3 This MnCO thermal decomposition can be rough MnO 2.

(2) and so on Tanabe natural manganese ore heating reduction MnO, then transform MnO as the manganese oxaminic acid ammonium salt, the latter after pyrolysis density big MnCO3, may make this MnCO3 thermal decomposition thick MnO2.

Tanabe, [2] natural heated revert MnO manganese ore, and then converting MnO manganese amino acid ammonium salt, the latter by heating MnCO3 of broken down into high density, this crude MnO2 MnCO3 thermal decomposition can be made.
