輕燒鎂球的提純方法 Purification method of light-burned magnesium balls

http://www.hakatayanoodle.com一、是浮選法是處理輕燒鎂球的主要提純方法之一，對于脈石礦物為滑石、石英等以硅酸鹽礦物為主的礦石，浮選時通常在礦漿自然ph下，添加胺類陽離子捕收劑和起泡劑就能達到良好的效果，將輕燒鎂球純度提高到95%-97%。 

二、是輕燒：菱鎂礦在750-1100℃溫度下煅燒稱輕燒;，其產品稱輕燒鎂粉。由于菱鎂礦燒減量一般為50%左右，因此通過輕燒，礦石中mgo含量幾乎可提高1倍。從這一意義上講，輕燒是Z有效的mgo富集手段。此外，輕燒也是菱鎂礦熱選和某些重選的預備作業。輕燒鎂具有很高的活性，是生產高體密鎂砂的理想原料。

三、是熱選法：利用菱鎂礦與滑石在熱學性質上的差異，經煅燒后造成二者之間的密度差與硬度差，再經選擇性破碎及簡單的篩分或分級使礦物得到分離。

For gangue minerals such as talc and quartz, which are mainly silicate minerals, flotation Normally at the natural pH of the pulp, adding amine cation collectors and foaming agents can achieve good results, and improve the purity of light-burned magnesium spheres to 95% -97%.

Second, is light burning: calcined magnesite at 750-1100 ℃ is called light burning; its product is called light burning magnesium powder. Because the loss of magnesite burning is generally about 50%, by light burning, the mgo content in the ore can be almost doubled. In this sense, light burning is the most effective means of MG enrichment. In addition, light burning is also a preparatory operation for magnesite thermal separation and some heavy separation. Light-burned magnesium has high activity and is an ideal raw material for producing high-density magnesia.

Third, it is a hot separation method: the difference in thermal properties between magnesite and talc is used to cause the density difference and hardness difference between the two after calcination, and then selective crushing and simple screening or classification to obtain minerals Separation.
