日产500吨菱镁矿浮选工艺

镁矿石应用领域

镁矿石主要用于耐火材料，其次用于化工原料，建材，冶炼金属镁等。当前菱镁矿的利用正在向高档化、合成化方向发展，尤其是烧结镁矿石，其纯度高，密度大，结晶量大。在市场竞争中，不断提高镁材深加工水平，提高产品档次，增加产品附加值是一种发展趋势。

Magnesium ore is mainly used for refractory materials, and secondly for chemical raw materials, building materials, smelting metal magnesium and so on. At present, the utilization of magnesite is developing in the direction of high-grade and synthesis, especially the sintered magnesia ore, which has high purity, high density and large amount of crystals. In the market competition, it is a development trend to continuously improve the deep processing level of magnesium materials, improve product grades, and increase the added value of products.

菱镁矿浮选工艺流程

镁矿采用浮选法,轻烧法，热选法，重选法，电选法，辐射选矿法，磁种分选法等多种选矿方法，针对不同的镁矿石选择相应的选矿方法，轻烧法是生产镁砂最有效的方法，浮选法是最常见的、最简单的、使用最频繁的方法，是菱镁矿选镁的选矿工艺。菱镁矿浮选法主要经历破碎—磨矿分级—浮选—浓缩四个过程。

Magnesium ore adopts flotation method, light burning method, thermal separation method, gravity separation method, electric separation method, radiation separation method, magnetic separation method and other methods of beneficiation. Choose the corresponding beneficiation method for different magnesium ore. Method, light burning method is the most effective method to produce magnesia, flotation method is the most common, simplest, and most frequently used method, it is the beneficiation process of magnesite magnesite. The magnesite flotation method mainly undergoes four processes: crushing, grinding and grading, flotation, and concentration.

破碎：

大块矿石由菱镁矿选矿用破碎机破碎，振动给料机将粒度小于200mm的菱镁矿原料送到颚式破碎机上破碎后，再由回转式破碎机破碎到较小的粒度，进入圆筛，粒度小于10mm不符合磨矿要求的，再进入破碎机破碎到0-10mm。

The large ore is crushed by a crusher for magnesite beneficiation. The vibrating feeder sends the magnesite material with a particle size of less than 200mm to the jaw crusher for crushing, and then is crushed to a smaller particle size by the rotary crusher , Enter the round screen, the particle size is less than 10mm and does not meet the grinding requirements, and then enter the crusher to crush to 0-10mm.

磨矿分级：

菱镁矿在经过破碎机破碎之后，粒度均小于10mm，给矿设备将破碎后的矿石送入到球磨机中进行单体解离，为了能够达到最佳的磨矿细度，要求磨矿粒度200目占70%以上。

After the magnesite is crushed by the crusher, the particle size is less than 10mm. The ore feeding equipment sends the crushed ore to the ball mill for monomer dissociation. In order to achieve the best grinding fineness, the grinding is required The 200 mesh ore size accounts for more than 70%.

浮选：

镁矿选矿流程中选别阶段主要用到的选矿设备是浮选机、搅拌机、浓缩机。采用单一的反浮选择工艺不能有效去除矿石中的杂质，选择的镁精矿氧化镁含量仍高达0.35%，因此镁矿的浮选工艺一般由反浮选(粗一扫)和正浮选(粗一精)构成，反浮选择所有尾矿，正浮选择镁精矿和中矿。

The beneficiation equipment mainly used in the separation stage of the magnesium ore beneficiation process is a flotation machine, a mixer, and a thickener. A single reverse flotation selection process cannot effectively remove impurities in the ore. The selected magnesium concentrate contains magnesium oxide as high as 0.35%. Therefore, the flotation process of magnesium ore generally consists of reverse flotation (coarse sweep) and positive flotation (coarse flotation). One fine) composition, all tailings are selected for anti-floating, and magnesia concentrate and medium ore are selected for positive floating.

浓缩：

通过球磨机将菱镁矿粉磨成菱镁矿粉，送至搅拌器与浮选药剂混合，再进行浮选和反浮选，最后进入浓缩器使矿浆中的矿粒絮状化，以达到减少水份的目的。

The magnesite powder is ground into magnesite powder by a ball mill, sent to the agitator and mixed with the flotation agent, and then flotation and reverse flotation are carried out, and finally into the concentrator to flocculate the ore particles in the slurry. In order to achieve the purpose of reducing moisture.
