   我们建议该选矿厂采用一重一浮联含选矿工艺流程,经洗矿机洗矿后矿石先用弱磁选机选出强磁性铁矿物,然后用浮选选出品位为15%左右的稀土泡沫,再用强磁选机选出弱磁性铁矿物,与强磁性铁矿物合并为铁精矿。对稀土泡沫用摇床选别得到粗精矿、中矿和尾矿、粗精矿和中矿用浮选继续选别,用环肟酸铵作捕收剂,经一粗一精浮选后,可得到稀土品位大子60%的精矿。如欲再提高精矿品位,可继续精选,经五次精选后,即可得到品位68%( REO)以上的稀土精矿。摇床中矿再经粗选、精选,可得到品位30%( REO)左右的稀土次精矿。 铁精矿的加工利用:选矿厂所得的铁精矿,主要用作炼铁原料。由于细粒铁精矿不宜直接加入炼铁高炉。须先加入熔剂,再高温烧结成块;或添加粘合剂压制成型;或滚成小球再烧结成球团;然后装入高炉内冶炼。高炉冶炼是把铁矿石还原成生铁的连续生产过程。在高内矿石中的铁及部分硅、锰被焦炭还原出来,与碳组成熔融的生铁,矿石中的脉石与石灰石组成熔渣,两者分别由炉缸的出铁口与出渣口流出。冶炼产品可以是供炼钢用的生铁,或者是铸造生铁,或者是高炉铁合金。炼钢主要的原料是生铁。生铁所含的碳及固有杂质(硅、锰、磷、硫和碳)都是在高炉冶炼,过程中从铁矿石及其他原料转入生铁的;而炼钢的任务就在于,在液体生铁中用某种方法引入某些数量的氧把这些元素烧掉,所以叫作氧化熔炼。在一定条件下氧和溶解于生铁中的硅、锰、磷以及某些数量的铁起反应,把它们变成氧化物。这些氧化物在金属中的溶解度都很小,因而差不多全部浮出并形成炉渣。当金属中各元素的含量经过一系列操作步骤已羟符合规格,而温度也符合浇铸的要求时,炼钢的任务就完成了。但是炼钢车间是以钢锭作为后产品,因此,炼钢的任务还包括铸锭工作。


There are many customers will consult a question is to buy the feeling of washing machine: 1, Zhonglian washing machine powerful, please rest assured! 2, the shutdown speed is very good, unlike other equipment, it takes a while; 3, the washing machine is specially designed for crushing ore. 4. The parts used in the washing machine are super wear-resistant and very powerful after heat treatment. 5. It's very grand and strong in the near view, and more magnificent in the distance. Now let's talk about the beneficiation of rare earth polymetallic iron ore!
The iron ore is a large-scale sedimentary metamorphic hydrothermal metasomatic Nb and re bearing polymetallic iron deposit. The ore contains 71 elements such as iron, niobium, rare earth, thorium, titanium, barium, manganese, fluorine and phosphorus, among which iron, rare earth, niobium and fluorine are of comprehensive utilization value. Iron minerals in the ore mainly include hematite, magnetite, pseudohematite and a small amount of pyrite, limonite and siderite. Rare earth minerals are mainly monazite, bastnaesite, praseodymium phosphorite, bastnaesite and so on. Niobium minerals are mainly niobium iron, Yellowstone, calcite, niobium calcium ore, ilmenite rutile, etc. Gangue minerals are mainly fluorite, spodumene, calcite, albite, albite, dolomite, quartz, chalcedony, mica, etc. the main characteristics of the iron ore are: many elements, complex composition, high comprehensive utilization value; many kinds of minerals, concentrated occurrence of rare earth elements; fine mineral distribution, uniform distribution. Therefore, it belongs to refractory ore.
We recommend that the concentrator should adopt one floatation combined with ore dressing technological process. After washing the ore by washing machine, the ore will first select ferromagnetic iron minerals with weak magnetic separator, then select rare earth foam with grade of about 15% by floatation, and then use the strong magnetic separator to select the weakly magnetic iron mineral and combine it with the ferromagnetic iron ore into iron concentrate. The rare-earth foam is selected by shaking table to get the flotation of coarse concentrate, middling and tailings, coarse concentrate and middling flotation. With the ammonium cyclic oxime acid as collector, the concentrate of rare earth grade 60% can be obtained after flotation. If you want to improve the concentrate grade again, you can continue to clean. After five times of cleaning, you can get the rare earth concentrate with a grade of more than 68% (REO). After roughing and cleaning, the re secondary concentrate with a grade of about 30% (REO) can be obtained. Processing and utilization of iron concentrate: the iron concentrate obtained from the concentrator is mainly used as iron making raw material. Because the fine iron concentrate should not be directly added to the blast furnace. It is necessary to add flux first, and then sinter into block at high temperature; or add binder to press and form; or roll into small ball and then sinter into ball; then put it into blast furnace for smelting. Blast furnace smelting is a continuous production process of reducing iron ore to pig iron. Iron and part of silicon and manganese in gaonei ore are reduced by coke to form molten pig iron with carbon, gangue and limestone in ore to form slag, both of which flow out from the iron tap and slag tap respectively. Smelting products can be pig iron for steelmaking, cast pig iron or blast furnace ferroalloy. The main raw material for steelmaking is pig iron. The carbon and inherent impurities (silicon, manganese, phosphorus, sulfur and carbon) contained in pig iron are all smelted in blast furnace, and transferred from iron ore and other raw materials to pig iron in the process. The task of steel-making is to introduce some amount of oxygen into liquid pig iron to burn these elements, so it is called oxidation smelting. Under certain conditions, oxygen reacts with silicon, manganese, phosphorus and some amounts of iron dissolved in pig iron, turning them into oxides. The solubility of these oxides in metals is very small, so almost all of them float out and form slag. When the content of each element in the metal has met the specification through a series of operation steps, and the temperature also meets the requirements of casting, the task of steelmaking is completed. But the steelmaking workshop takes ingot as the final product, so the task of steelmaking also includes ingot casting.
