Chalcopyrite (CuFeS₂) and pyrite (FeS₂) are common sulfide minerals that often coexist in ores. Among them, chalcopyrite is one of the main minerals for obtaining copper, and pyrite coexists with it, which will affect the quality of copper concentrate. In the beneficiation process of copper ore, effective separation of chalcopyrite and pyrite is crucial to improving the grade and recovery rate of copper concentrate. However, there are many similarities between the two in crystal structure, chemical composition, physical properties, etc., and separation is somewhat difficult. At present, the common chalcopyrite copper ore beneficiation and separation methods are mainly flotation, magnetic separation and gravity separation.Details>>
Vanadium-titanium magnetite is a complex polymetallic ore, and its main feature is the complex and diverse mineral composition. In addition to containing a large amount of magnetite (Fe₃O₄) as the main iron mineral component, it is also accompanied by rich ilmenite (FeTiO₃) and a certain amount of vanadium. These useful minerals are usually closely symbiotic. In addition, there are a variety of gangue minerals in the ore, such as feldspar, quartz, pyroxene, olivine, etc. The embedded particle size of vanadium-titanium magnetite is uneven, ranging from coarse particles to fine particles, which makes its beneficiation difficult. This question is about the vanadium-titanium magnetite beneficiation method and process analysis!Details>>
Chromite is an important strategic metal mineral, its main components are iron, chromium and oxygen, and may also contain a small amount of magnesium, aluminum, silicon and other elements. In terms of beneficiation, it is mainly determined by the properties of chromite ore, but the general principle process is usually crushing-grinding-separation (gravity separation, magnetic separation, flotation)-dehydration. However, when chromite beneficiation is operated, what equipment is required for each process? Let's learn about it together.Details>>
Siderite is a carbonate mineral with the chemical formula FeCO₃. Siderite is usually gray, light yellow or brown, with a glassy luster. It is a weakly magnetic mineral and often coexists with other minerals. The ore structure is complex and the iron content is unstable. In terms of beneficiation methods, due to the difference in the ore properties of siderite, its beneficiation process is also different, and the siderite beneficiation equipment is also different. Let's take a look at what are the commonly used equipment for siderite beneficiation?Details>>
Rutile is a titanium-containing oxide mineral, and its chemical formula is TiO₂. Rutile is usually dark red, brown or black, with a metallic luster, and its hardness is relatively high. The crystal structure of rutile is tetragonal, and common crystal forms include columnar and needle-shaped. Rutile is mainly produced in metamorphic rocks and igneous rocks, and coexists with minerals such as ilmenite and magnetite. This article mainly introduces rutile beneficiation methods!Details>>
Phosphorus in phosphorus-containing iron ore mainly exists in the form of phosphate, and the presence of phosphorus directly affects the quality of iron ore. Therefore, dephosphorization treatment is required. At present, the common iron ore dephosphorization processes include flotation, magnetic separation, chemical leaching, oxidation roasting-magnetic separation combined method and microbial method.Details>>
Rutile is an important raw material for titanium production. Most of my country's rutile resources are low-grade primary ore resources with fine-grained distribution. The TiO2 content is generally 2% to 4%. The ore dressing process is usually complicated. Flotation is often used as the main separation method in ore dressing. In the flotation process, the selection of agents is particularly important. The following article will focus on the types of rutile flotation agents.Details>>
In order to improve the comprehensive utilization rate of associated valuable elements and resources, people have conducted a lot of research and improvements on the flotation separation process of pyrite and chalcopyrite. These improvements are aimed at adapting to the changes in mineral flotation characteristics and ore properties, and optimizing resource recovery rate and processing efficiency. At present, there are five commonly used flotation separation process flows: direct flotation separation process flow, preferential flotation process flow, mixed-preferential flotation process flow, mud and sand separation process flow, and combined beneficiation and smelting process flow. Each process has its specific applicable conditions and operating characteristics, which can effectively cope with different ore types and processing requirements. This article will introduce the status of these five flotation separation process flows in detail, and explore their respective scope of application, process flow and advantages and disadvantages.Details>>
When flotating high carbon chromite, the main method is to make the surface of chromite hydrophobic by adding flotation agents, and then separate chromite from gangue minerals by mineralization of bubbles. The selection of agents is particularly important in the flotation process. This article will focus on the types of commonly used concentrated high carbon chromite flotation agents.Details>>
High carbon chromite is an important strategic resource, widely used in metallurgy, chemical industry and other fields. The main mineral resources are chromite, followed by olivine, pyroxene and a small amount of impurity minerals such as magnetite, hematite and pyrite. The symbiotic relationship between minerals in this ore is close, the embedded particle size is fine, and the beneficiation is difficult. The commonly used iron ore beneficiation processes are gravity separation, magnetic separation and flotation.Details>>
Ilmenite is the main mineral for obtaining titanium and iron resources, but due to the complex properties of ilmenite ore, sometimes it is difficult to effectively recover the useful components in the mineral by using a single beneficiation method. Therefore, multiple beneficiation methods can be combined to form a combined process to improve the recovery rate of ilmenite beneficiation.Details>>
Although my country has a large reserve of iron ore, most of it is "poor, fine and impure", with large differences in mineral properties and great difficulty in beneficiation. At present, the process of beneficiation of hematite that can be processed includes stage grinding or continuous grinding, coarse and fine separation, gravity separation-high gradient magnetic separation-anion reverse flotation process, continuous grinding, strong magnetic separation-anion reverse flotation process and roasting, stage grinding-high efficiency magnetic separation-cation reverse flotation process. However, the specific selection depends on the properties of the hematite ore. Below we take a fine-grained hematite as an example to introduce one of the hematite beneficiation process flows.Details>>
