高视密度化学二氧化锰的中间品重质碳酸锰的制备

Preparation of Heavy Manganese Carbonate From A Intermediate of High Visual─Density Manganese Dioxide

介绍了制备重质碳酸锰的工艺路线和优惠条件。放大试验所得重质碳酸锰平均振实视密度２．１８ｇ／ｃｍ￣３，最高达２．３３ｇ／ｃｍ￣３，平均含Ｍｎ４６．２８％。该工艺解决了高视密度化学二氧化锰制备中的一大难题。

A technological process of manufacturing heavy mangnese carbonate and its favorable conditions have becn presented. The average vibratory compaction apparent density of the heavy mangnese carbonate prepared,fred from the enlarged text is 2.18g/cm￣3, up to 2.33g/cm￣3(max).the average mangnese content is 46.28%.The difficulty in manufacturing high apparent. density chemical mangnese dioxide has been resolved.
