轻烧镁球的提纯方法 Purification method of light-burned magnesium balls

http://www.ykbhlm.com一、是浮选法是处理轻烧镁球的主要提纯方法之一，对于脉石矿物为滑石、石英等以硅酸盐矿物为主的矿石，浮选时通常在矿浆自然ph下，添加胺类阳离子捕收剂和起泡剂就能达到良好的效果，将轻烧镁球纯度提高到95%-97%。 

二、是轻烧：菱镁矿在750-1100℃温度下煅烧称轻烧;，其产品称轻烧镁粉。由于菱镁矿烧减量一般为50%左右，因此通过轻烧，矿石中mgo含量几乎可提高1倍。从这一意义上讲，轻烧是最有效的mgo富集手段。此外，轻烧也是菱镁矿热选和某些重选的预备作业。轻烧镁具有很高的活性，是生产高体密镁砂的理想原料。

三、是热选法：利用菱镁矿与滑石在热学性质上的差异，经煅烧后造成二者之间的密度差与硬度差，再经选择性破碎及简单的筛分或分级使矿物得到分离。

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.
