Based on the design of the high temperature shaft kiln , for the calcination of limestone , dolomite and magnesite ，用于石灰石白云石和菱镁矿的煅烧。这种低成本的窑型是对生产的石灰或白云石中要求
Atomic - absorption spectrophotometry of impurties in clay , feldspar , magnesite , calcite , dolomite , talc , quartz for electron ceramic raw materials 电子陶瓷原材料粘土长石菱镁矿方解石白云石滑石石英中杂质的原子吸收分光光度测定法
In the field of thermal treatment of industrial minerals limestone , dolomite , magnesite , clay , ores and various derivatives from industrial processes 工业矿石石灰石，白云石，菱镁矿，粘土，矿石和工业处理后的各种派生物的热处理领域的
Halehate magnesite mine lies at upstream of halehate gully north to kaidu river 114km away from hejing county northwestwards . there are 14 relative big - scale ore bodies in the deposit . its reserves is more than 0 . 13 billion tons 哈勒哈特菱镁矿位于和静县城西北114公里开都河北的哈勒哈特沟上游，矿床中规模较大的矿体14个，该矿储量在1 . 3亿吨以上。
It is pointed out that there exist abundant precambrian mineral resources in china , forming numerous large - superlarge iron , copper , lead , zinc , nickel , gold , ree , manganese , graphite , magnesite , talc , boron , phosphorus , pyrite , rutile and vermiculite deposits 指出中国前寒武纪蕴藏著丰富的矿产资源，形成了众多的铁、铜、铅锌、镍、金、稀土、锰、石墨、菱镁矿、滑石、硼、磷、硫铁矿、金红石、蛭石等大型超大型矿床。
At present , annual output is 4 million tons in whole china , 2 . 2 million tons for export and 1 . 8 million tons for domestic market . but it is still blank in magnesite refractory for northwest area ; therefore development of halehate magnesite mine is of great market prospect and economic benefit 目前，全国年产400万吨，对外出口220万吨，内销180万吨，而西北地区镁质耐火材料尚属空白，因此开发哈勒哈特菱镁矿具有很好的市场前景和经济效益。
