求翻译：此法是将硝酸锰溶液通过加热, 使其分解为二氧化锰, 与碳酸锰热分解法一样, 也是沿用已久的方法。硝酸锰热分解法是将锰矿用硝酸浸取制得硝酸锰溶液, 过滤浓缩后进行热分解, 制得粗二氧化锰。尾气用水或稀硝酸吸收, 生成硝酸可回收使用。粗二氧化锰经精制后得高质量二氧化锰。是什么意思？

This method is by heating manganese nitrate solution, to be broken down into manganese dioxide, manganese carbonate thermal decomposition, but also long-established methods. Manganese nitrate thermal decomposition of manganese with nitric acid leaching system manganese nitrate solution, after filtra

This law is to manganese nitrate solution by heating, so that it breaks down to 2, manganese oxide and manganese thermal decomposition, are also has been used for a long time. Nitric acid which is the thermal decomposition method using manganese nitrate nitric acid has been flooding the system solut

This law is the manganous nitrate solution through the heating, causes it to decompose into the manganese dioxide, is same with the manganese carbonate thermal decomposition law, also continues to use already the long method.The manganous nitrate thermal decomposition law is takes the manganese ore

This method is manganese nitrate solution by heating, making it down to manganese dioxide, manganese carbonate thermal decomposition method, is also well-established methods. Manganese nitrate is by thermal decomposition of nitrate leaching manganese ore manganese nitrate solution, thermal decomposi
