用外加热回转窑生产高纯活性氧化镁回收二氧化碳新工艺

针对当前镁制品生产过程中存在的严重资源浪费和环境污染严重的问题,提出以废弃菱镁矿渣为原料,利用新型外加热回转窑生产高纯氧化镁,并从生产废气中回收食品级液态二氧化碳的新工艺。

Aimed at the problems of resources waste and environment pollution severely in the production process of magnesium products, a new production craft with waste magnesite residue as raw material which used rotary kilns heated in the exterior to produce high-pure magnesium oxide and recovered food class liquid carbon dioxide from the waste gas of the process was put forward.
