Description
技术领域technical field
本发明涉及一种钒钛磁铁矿选矿工艺，属于选矿技术领域。The invention relates to a vanadium-titanium magnetite beneficiation process, belonging to the technical field of beneficiation.
背景技术Background technique
钒钛磁铁矿分布于世界各地，由于矿床的条件有所差异，因此其化学组成分及比例也各不相同。再加上不同地区的钒钛磁铁矿可选性存在差异，导致其生产组合的铁、钒、钛含量各不相同。我国钒钛磁铁矿床储量丰富，分布广泛，已探明储量高达150亿吨，主要分布在河北承德地区、四川西昌地区等。其中，攀枝花是我国钒钛磁铁矿的主要成矿带，位于四川西昌地区，该地区生产出来的钒钛磁铁矿矿石性质较特殊。东南亚、非洲等地也盛产钒钛磁铁矿，但是工艺技术很难将其完全分离，提炼精度不高。这样也就将四川攀枝花的钒钛磁铁矿的全球性价值推广的更高。Vanadium titanomagnetite is distributed all over the world, and its chemical composition and proportion are also different due to the different conditions of the deposit. In addition, there are differences in the selectivity of vanadium-titanium magnetite in different regions, resulting in different iron, vanadium and titanium contents in its production mix. The reserves of vanadium-titanium-magnetite deposits in my country are abundant and widely distributed. The proven reserves are as high as 15 billion tons, mainly distributed in the Chengde area of Hebei and the Xichang area of Sichuan. Among them, Panzhihua is the main metallogenic belt of vanadium titanomagnetite in my country. It is located in Xichang area, Sichuan. The properties of vanadium titanomagnetite ore produced in this area are special. Southeast Asia, Africa and other places are also rich in vanadium titanomagnetite, but it is difficult to completely separate it by process technology, and the refining precision is not high. In this way, the global value of vanadium-titanium-magnetite in Panzhihua, Sichuan will be promoted higher.
由于开采年限过长导致中高品位铁矿资源大幅度减少，铁矿石紧缺问题日益突出，急需补充有效途径优化选矿技术。生产实践表明，选矿工艺流程优化后，得到了精矿品位77.22％、尾矿品位10.12％的佳绩。但优化后的工艺流程仍存在一定缺陷与问题。Due to the long mining period, the resources of medium and high grade iron ore have been greatly reduced, and the shortage of iron ore has become increasingly prominent. The production practice shows that after the beneficiation process is optimized, the concentrate grade is 77.22% and the tailings grade is 10.12%. However, the optimized process still has some defects and problems.

下面结合实施例对本发明的具体实施方式做进一步的描述，并不因此将本发明限制在所述的实施例范围之中。The specific embodiments of the present invention will be further described below with reference to the examples, but the present invention is not limited to the scope of the described examples.
实施例1Example 1
如图1所示，破碎工艺优化流程为三段一闭路流程,最终产品粒度为-12mm。粗碎产品经双层筛预先筛分，-25mm产品经圆筒洗矿筛洗矿筛分,得到-5mm产品通过湿式弱磁选抛尾,抛废率3.95％,TiO2品位为5.00％。检查筛分+25mm产品采用磁滑轮干式抛尾,抛废粒度为-80mm,TiO2品位为5.00％。经2次抛废后可使得矿石品位TFe达到22.89％,TiO2品位达到10.62％,入磨矿石量减少14％,抛废效果明显。As shown in Figure 1, the optimization process of the crushing process is a three-stage closed-circuit process, and the final product particle size is -12mm. Coarse crushed products are pre-screened by double-layer sieves, -25mm products are washed and screened by cylindrical washing screen, and -5mm products are obtained by wet weak magnetic separation and discarded. The discard rate is 3.95%, and the TiO 2 grade is 5.00%. Check and sieve +25mm products using magnetic pulley dry tail throwing, the throwing particle size is -80mm, and the TiO 2 grade is 5.00%. After 2 times of scrapping, the ore grade TFe can reach 22.89%, TiO 2 grade can reach 10.62%, and the amount of grinding ore can be reduced by 14%, and the scrapping effect is obvious.
如图2所示，磨矿工艺优化流程为阶段磨选、阶段磁选，第一阶段磨矿粒度为-0.076mm占55％,破碎阶段已经对-5mm进行了抛尾,二段磨矿粒度为-0.076mm占70％，磁选采用GMT脱磁器进行。当磨矿细度为-0.2mm时,精矿TFe品位为55％左右,已接近最高值。As shown in Figure 2, the optimization process of the grinding process is stage grinding and stage magnetic separation. The grinding particle size of the first stage is -0.076mm, accounting for 55%. -0.076mm accounted for 70%, and the magnetic separation was carried out with a GMT demagnetizer. When the grinding fineness is -0.2mm, the TFe grade of the concentrate is about 55%, which is close to the highest value.
为了保证选矿效率发挥最大限度，对人磨粉矿品位给予提升；为保证破碎产品粒度，可使用诺德伯格破碎机，并以WAY振动筛取代普通振动筛。为保证合格产品通过筛分进入下一道工序，提升破碎效率，规避对应破碎作业干扰，将破碎产品粒度做到最大程度降低。In order to ensure the maximum beneficiation efficiency, the grade of human milled ore is improved; in order to ensure the particle size of the crushed products, a Nordberg crusher can be used, and a WAY vibrating screen is used to replace the ordinary vibrating screen. In order to ensure that qualified products enter the next process through screening, improve crushing efficiency, avoid the interference of corresponding crushing operations, and minimize the particle size of crushed products.
在磁选时选用永磁筒式干选磁选机，可降低生产成本，优化工艺流程，提高综合经济效益，使超低品位磁铁矿石开发的经济效益基本条件得到满足，此干磁机以不提高总尾矿石为基础的前提下进行使用，最大程度降低对选别体统的干扰。The use of permanent magnet drum type dry magnetic separator in magnetic separation can reduce production costs, optimize technological processes, improve comprehensive economic benefits, and meet the basic economic benefits for the development of ultra-low-grade magnetite ore. It is used on the premise of increasing the total tailings to minimize the interference to the sorting system.
磨选工艺优化方案：在开展磨选作业期间，为降低磁团聚对分级效率的影响，可适当增设GMT脱磁器。为简化流程，将分级作业改换为MVS高频振网筛。为解决磨矿效果差、再度作业浓度提升等问题，可再次研磨一次磁选产品磨。除此之外，在其改善后，将部分矿石对有用矿石中干扰给予最大程度排除，同时对人筛的合格产品含量具有显著提升作用。Grinding process optimization plan: During the grinding operation, in order to reduce the impact of magnetic agglomeration on the classification efficiency, a GMT demagnetizer can be appropriately added. To simplify the process, the grading operation was changed to MVS high-frequency vibrating screen. In order to solve the problems of poor grinding effect and increased concentration of operation again, the magnetic separation product grinding can be ground again. In addition, after its improvement, the interference of some ores in the useful ores is eliminated to the greatest extent, and the content of qualified products in the human sieve is significantly improved.
该工艺流程操作简单，回收利用率高，对矿石适应能力强以及设备选矿效率高等，其中以使用高科技含量新型设备中工艺程序科学、合理性等特点具有一定突出，同时对它工艺与技术中的先进性更具有一定说服力。为保证选矿系统中高效能可在整个过程中得到充分发挥，对设备以及工艺中长处进行集中转换，进而对相关干扰因素给以排除。结合相关生产实践，对MVS高频振网筛质效率与普通振动筛具有显著提高给予一定依据，在工艺流程运作过程中，为最佳优选设备之一。The technological process is simple in operation, high in recovery rate, strong in adaptability to ore and high in equipment beneficiation efficiency. Among them, the use of new high-tech equipment has certain outstanding features such as scientific and rational process procedures. The advanced nature is more convincing. In order to ensure that the high efficiency in the beneficiation system can be brought into full play in the whole process, the equipment and the advantages of the process are converted in a centralized manner, and then the relevant interference factors are eliminated. Combined with relevant production practices, it provides a certain basis for the significant improvement in the quality efficiency of MVS high-frequency vibrating screen and ordinary vibrating screen. In the process of technological process operation, it is one of the best and preferred equipment.
