Description

一种磁性顽石精细除铁分选***Magnetic hard stone fine iron removal sorting system 技术领域Technical field
本发明属于磁性分离技术领域，具体涉及一种磁性顽石精细除铁分选***，其是针对磁性顽石物料除铁的特殊问题专门设计的，彻底解决磁性顽石物料与铁件的混杂分离的难题。The invention belongs to the technical field of magnetic separation, and particularly relates to a magnetic hard stone fine iron removal sorting system, which is specially designed for the special problem of removing iron from magnetic hard stone materials, and thoroughly solves the mixed separation of magnetic hard stone materials and iron parts. Puzzle.
背景技术Background technique
随着铁矿市场的过剩和近一段时间甚至长期低迷的铁矿走势，对于各大选矿厂来说，改善选矿工艺、降低铁精粉的生产成本成为亟待解决的问题。With the oversupply of the iron ore market and the trend of iron ore in the recent period and even long-term downturn, improving the beneficiation process and reducing the production cost of iron concentrate have become an urgent problem for major ore dressing plants.
对于降低铁精粉生产成本目前可以通过开采高品位原矿或改善选矿工艺来实现。由于国内矿山普遍贫矿，富矿极少，对于国内绝大部分选厂而言开采高品位原矿这一途径几乎是不能实现的，所以只能通过提升选矿工艺来降低铁精粉的生产成本；而选矿工艺又可通过“多碎少磨”或“少磨多选”等途径来进行改善，达到降低生产成本的目的。The reduction of iron concentrate production costs can now be achieved by mining high grade ore or improving the beneficiation process. Due to the general poor mines in the domestic mines, there are very few rich mines. For most domestic plants, the exploitation of high-grade ore is almost impossible, so the production cost of iron fines can only be reduced by upgrading the beneficiation process; The beneficiation process can be improved by means of “multiple crushing and less grinding” or “less grinding and multiple selection” to achieve the purpose of reducing production costs.
传统的磨矿流程经多年的生产实践检验,表现出工艺流程长,所用设备型号和数量多,金属消耗量大,基建投资和生产费用高等缺点。半自磨回路及其设备的研发提供一种非常优越的磁选思路，半自磨回路由于其流程简单(省去了两段破碎机及筛分设备),配置方便,投资省,因此众多研究者投入大量精力和财力进入半自磨设备的实用研究中，随着半自磨技术对选矿工艺的提高，混杂在磨机里的铁球随着尾矿排出，进行后续处理，其中越是品质较好的矿石磁性越强，这样就很难用原有的磁选技术将其进行分离，使得部分选厂不能采用半自磨技术。The traditional grinding process has been tested by many years of production practice, showing the short process flow, the types and quantities of equipment used, the large metal consumption, the high capital investment and high production costs. The development of semi-self-grinding circuit and its equipment provides a very superior magnetic selection idea. The semi-self-grinding circuit is simple in its process (eliminating the two-stage crusher and screening equipment), convenient in configuration and low in investment, so many studies Investing a lot of energy and financial resources into the practical research of semi-autogenous grinding equipment, with the semi-self-grinding technology improving the beneficiation process, the iron balls mixed in the mill are discharged along with the tailings for subsequent processing, the more the quality The better the magnetic strength of the better ore, it is difficult to separate it with the original magnetic separation technology, so that some of the plants can not use semi-self-grinding technology.
在铁矿石的开采及分选中，针对磁性顽石物料除铁的特殊问题一直是困扰企业的一大问题，如何彻底解决磁性顽石物料与铁件的混杂分离的难题是众多技术研究者不可回避的难题，但是在实际生产中一直没有有效解决。与此专项技术相关分离技术普遍存在着磁场强度高难以同时保证高品位和高精矿回收率；或设备自动化水平很低，需要大量的人力去维护调节，因此增大了生产成本等问题。 In the mining and sorting of iron ore, the special problem of removing iron from magnetic hard stone materials has always been a big problem for enterprises. How to completely solve the problem of mixed separation of magnetic stone materials and iron parts is not enough for many technical researchers. The problem of avoiding, but it has not been effectively solved in actual production. The separation technology associated with this special technology generally has a high magnetic field strength and it is difficult to ensure high-grade and high-concentration recovery rate at the same time; or the equipment automation level is very low, requiring a large amount of manpower to maintain the adjustment, thus increasing the production cost and the like.
发明内容Summary of the invention
为了解决上述问题，本发明人经过多次设计和研究，提出了一种磁性顽石精细除铁分选***。其在保证高回收率的同时可以达到理想可选精矿品位、处理量大、自动化程度高等优点。In order to solve the above problems, the inventors have proposed a magnetic hard stone fine iron removal sorting system through multiple designs and researches. While ensuring high recovery rate, it can achieve the ideal optional concentrate grade, large processing capacity and high degree of automation.
