Limonite lump concentrator

1. The main iron minerals are pseudo hematite, semi pseudo hematite, gangue minerals are mainly quartz, followed by hornblende, chlorite, etc. the ore presents obvious banded structure with fine disseminated particle size. The particle size of pseudo hematite and quartz is generally 0.02-0.2mm, and the ore needs to be ground to - 200 mesh 80% g / T, The flotation pH value is 8.5-9.5, the pulp temperature is 30-33 ℃, and the collector is a mixture of 390 g / T oxidized paraffin soap and 130 g / t tall oil. The gravity separation method is mainly used to separate weak magnetic hematite from iron ore. there are two kinds of applications: one is that the geological grade of the deposit is high (about 50%), but the ore body is thin or there are many intercalations, and the waste rock is mixed in ring mining, In order to make the ore lean, this kind of ore can be crushed without grinding. In the case of coarse particle size, the coarse tailings can be discarded by gravity separation, so as to restore the geological grade and obtain coarse medium grade concentrate, or further processed, or directly sent to the blast furnace for smelting, which is called coarse gravity separation, The other is to separate the iron mineral monomer by crushing and grinding the fine disseminated red ore or mixed ore (i.e. weakly magnetic red ore and strongly magnetic magnetite), and then to obtain fine-grained high-grade concentrate by gravity separation or magnetic gravity separation, This is called hematite fine particle gravity separation.

2. Hematite limonite magnetic separation is a kind of magnetic separation equipment with high magnetic field intensity, which is used for hematite limonite magnetic separation. It is mainly used for beneficiation of weak magnetic minerals and iron removal of non-metallic minerals
the magnetic separation of hematite and limonite can not only be used as the equipment for preconcentration and roughing of coarse weak magnetic iron ore. It can also be used as main separation equipment for some ores. It has the advantages of simple process, convenient proction management and low concentrate grade.

3. Jiangxi Hengcheng mineral processing equipment Co., Ltd. here introces a new type of limonite beneficiation method, hoping to help you
the main component of limonite is iron oxide, which belongs to weak magnetic iron ore, with poor permeability. At the same time, limonite has a high degree of oxidation, easy to slime, and part of limonite contains a lot of slime, Before beneficiation, it is necessary to carry out ore washing operation to ensure the smooth progress of beneficiation process
conventional limonite beneficiation methods mainly include gravity separation, flotation and high intensity magnetic separation. The most commonly used method is gravity separation. Gravity separation has the advantages of high beneficiation efficiency, high beneficiation index, no pollution, low energy consumption, small equipment investment and low operation cost. In the past, shaking table was often used as the main equipment of limonite gravity separation, so the beneficiation index could not reach the ideal level
the new limonite beneficiation method adopts the latest mining diaphragm jig to separate and purify the coarse, medium and fine-grained limonite. The beneficiation effect is remarkable. It has been put into use in many countries and regions, and has achieved great success
the new limonite beneficiation method is to determine the crushing size of the ore according to the dissemination characteristics of the limonite ore, and then wash and purify the ore with jigs of different sizes to obtain the final concentrate. Generally, the disseminated particle size of limonite is relatively coarse, and a higher degree of monomer dissociation can be obtained by crushing. Because limonite is easy to be slimed, it is also necessary to avoid over sliming caused by grinding in the beneficiation process. When fine grinding is needed, it is better to use fine crushing effect as far as possible, and rod mill is not easy to be over ground for fine crushing
the new type of mining diaphragm jig can effectively deal with 0-50mm coarse, medium and fine limonite. It has significant beneficiation effect on limonite with obvious specific gravity difference within the effective separation range, high separation precision and high beneficiation efficiency. It has been widely used in many regions and countries, and has the advantages of energy saving, high efficiency and environmental protection, It has changed the situation that it is difficult to improve the grade of weak magnetic iron ore
the new limonite beneficiation method is mainly to crush and screen the raw ore according to the ore processing and dissemination results, screen out limonite mineral materials with high degree of monomer dissociation, and then divide them into different size fractions to be separated by jig, which can separate limonite of 0-8, 8-25 and 25-50mm, The concentrate and tailings separated by jigging machine respectively enter the dewatering screen, and then are transported to the concentrate yard and tailings plant by belt conveyor.

How to use limonite processing equipment to select limonite. Low intensity magnetic separation is combined with gravity separation, flotation and high intensity magnetic separation, that is, to use low intensity magnetic rotation to recover magnets, mine gravity separation, flotation, or high intensity magnetic separation to recover weak part of speech iron minerals, magnetization and sintering magnetic separation method or the parallel process with other methods, which is similar to the magnetization and sintering of single weak magnetic iron ore, However, in the parallel process of magnetization roasting magnetic separation and other mineral processing methods, low intensity magnetic separation combined with other methods and selective flocculation desliming method are adopted for fine ore. The technological process and separation method of hematite mineral processing equipment are as follows:
the ore processed by the plant is hematite hard rock, the main iron minerals are pseudo hematite, semi pseudo hematite, the gangue minerals are mainly quartz, followed by hornblende, chlorite, etc, The ore has obvious banded structure and fine disseminated particle size. The particle size of pseudo hematite and quartz is generally 0.02-0.2mm. The ore needs to be grinded to 80% g / T of - 200 mesh to form 20% aqueous solution, which is added to the second stage grinding machine. The flotation pH value is 8.5-9.5, the pulp temperature is 30-33 ℃, and the collector is a mixture of 390g / T oxidized paraffin soap and 130g / t tall oil, It is mainly used for the separation of weak magnetic hematite. There are two applications: one is that the geological grade of the deposit is high (about 50%), but the ore body is thin or there are many intercalations. Waste rock is mixed in ring mining, which makes the ore lean. For this kind of ore, only crushing without grinding can be used. In the case of coarse particle size, coarse tailings can be discarded by gravity separation, so as to restore the geological grade and obtain coarse medium grade concentrate, Or further processing, or directly to the blast furnace smelting, this is called coarse-grained gravity separation, the other is for the dissemination of fine-grained red ore or mixed ore (including weak magnetic red ore and strong magnetic magnetite), after crushing, grinding to separate the iron mineral monomer, through gravity separation or magnetic gravity separation, to obtain fine-grained high-grade concentrate, This is called hematite fine gravity separation.

5 Working principle of limonite beneficiation equipment (limonite dry magnetic separator)
the raw ore of 0.5-5mm is sent to the upper hopper, and the material is distributed by vibrating motor, and the discharge quantity can be accurately adjusted by hand wheel. The magnetic roller is driven by the speed regulating motor, and the speed is adjusted by the speed regulating meter, which can control the output and concentrate grade of the magnetic separator. The ore particles are sent to the upper magnetic roller for separation by the conveyor belt. Because the limonite particles are magnetic, they are immediately adsorbed on the magnetic roller by the strong magnetic field, while the gangue particles (Miscellaneous stone and sand) are not magnetic (very weak magnetic), and the strong magnetic force of the magnetic roller does not proce suction on them. With the rotation of the magnetic roller, the ore particles are always absorbed on the magnetic roller, When the magnetic roller turns to the front position, the gangue particles are thrown out in front of the separator plate (the grade of the concentrate can be adjusted by changing the angle of the separator plate). When the ore particles continue to be brought to the demagnetization area by the magnetic roller, they automatically fall into a collector bucket to collect the concentrate procts. As the gangue falling from the upper magnetic roller also contains some ore particles with weaker magnetism, they will enter the lower magnetic roller to continue the magnetic separation. The finished ore particles after magnetic separation will enter the second selection hopper to collect as finished procts, and the thrown gangue will be discharged through the tailing port, so the magnetic separation process is over. Because the gangue in the raw ore is abandoned, the grade of limonite is improved. The power consumption of limonite dressing equipment (limonite dry magnetic separator) is only about 4kw, and the input cost of magnetic separation is quite low. On August 15, 2007, the State Intellectual Property Office of the people's Republic of China (SIPO) has granted a utility model patent with the patent number of zl200520105881. X.

9. In general, it can be raised to about 55, but limonite with more magnetite can be raised to more than 60.

10. Commonly used mineral processing methods:
first, gravity separation method
gravity separation method is based on the difference of mineral relative density (usually called specific gravity) to separate minerals. The mineral particles with different densities in the moving medium (water, air and heavy liquid) are affected by hydrodynamic and various mechanical forces, resulting in suitable loose stratification and separation conditions, so that the mineral particles with different densities can be separated< Second, flotation method: according to the difference of physical and chemical properties of mineral surface, the useful minerals are selectively attached to the bubbles by flotation reagent treatment, so as to achieve the purpose of separation. Non ferrous metal ores such as copper, lead, zinc, sulfur and molybdenum are mainly treated by flotation; Some ferrous metals, rare metals and some non-metallic ores, such as graphite ore and apatite, are also separated by flotation< Third, magnetic separation:
magnetic separation is based on the different magnetic properties of minerals. Different minerals are subject to different forces in the magnetic field of the magnetic separator, so as to be separated. It is mainly used to separate ferrous metal ores (iron, manganese and chromium); It is also used for the separation of nonferrous and rare metal ores
however, the composition of each ore is different, and the mineral processing technology used is also different. It is recommended that you go to Sanxiong Heavy Instry Co., Ltd. for a detailed understanding. Their engineers are very experienced.
