Manganese is used in many fields such as metallurgy, machinery, and fire protection. There are two common types of manganese ore, one is manganese oxide and the other is manganese carbonate. Manganese carbonate is the main source of manganese, but it has been mined for many years and is easy to select. It is becoming less and less, mostly hard-to-select manganese carbonate with embedded particle size.
There are many grinding processes commonly used at home and abroad. In production practice, each process has advantages and disadvantages. It is necessary to choose a process that has many advantages and disadvantages and is relatively simple and convenient in industrial production. The factors that affect the selection of the grinding process mainly include ore properties, equipment performance, energy and steel consumption, investment in process solutions, and production costs.
There are many types of iron ores in nature. The types of iron ores that have been widely developed and utilized mainly include magnetite ore, hematite ore, siderite ore and polymetallic complex iron ore. With the continuous development of mineral processing technology, the mineral processing technology for different types of iron ore has also undergone significant changes, and the mineral processing indicators have also increased accordingly. The following will introduce you to the above-mentioned iron ore beneficiation processes to help you better understand the iron ore separation process.
Spodumene is one of the most widely developed minerals. Since spodumene often coexists with quartz, feldspar, mica and other gangue minerals, it will cause the spodumene mineral to become more muddy, thus affecting the beneficiation effect of spodumene and making it more difficult to be beneficiated.
The mineral beneficiation process that the mineral processing plant needs to select and formulate should have the characteristics of mature technology, advanced technology, stable and reliable production, and high economic benefits. Because the design of the mineral beneficiation process is the primary task of the mineral processing plant design, during the process design process, attention should be paid to various conditions and influencing factors, overly subjective and one-sidedness should be avoided, and a reasonable and efficient mineral processing plan should be selected.
The separation of nickel ores is mainly aimed at nickel sulfide ores, among which flotation is the main problem in the flotation of nickel ores during the separation of copper and nickel. Because copper is a harmful impurity in nickel ore, it is not conducive to the application of nickel in various aspects. The separation of copper and nickel can be carried out during the mineral processing and smelting process. Due to the high cost of smelting separation and the many restrictions on conditions, the flotation method is basically used for the separation of copper and nickel.
Tungsten is a refractory metal with a melting point as high as 3410±20°C. It is the metal with the highest melting point and has high-temperature strength and hardness. The vapor pressure is still very low at high temperatures of 2000~2500℃. Tungsten is used in industries such as steel, machinery, mining, petroleum, rockets, aerospace, electronics, nuclear energy, military industry and light industry in the form of alloy elements, tungsten carbide, metal materials or compounds. It is indispensable to various sectors of the national economy and cutting-edge technology. Important material.
With the rapid development of the global mining industry, the number of ore tailings ponds is increasing year by year, and most concentrators adopt a wet direct discharge method for tailings. In this treatment method, the tailings naturally precipitate, resulting in reduced dewatering efficiency. In order to better solve the problems of slow dehydration of tailings and environmental pollution, the concentrator can adopt the method of dry storage of tailings. There are different forms of dry storage of ore tailings, and there are also various ways to remove moisture from the tailings.
There are many types of gold mines in nature. Considering the actual situation of mineral processing, gold mines can be divided into sulfide-poor gold mines, polysulfide gold mines, gold-bearing polymetallic ores, gold-bearing copper ores, etc. Depending on the type of ore, the treatment methods used by the concentrator are also different. For example, flake, leaf and plate gold are mostly recovered by flotation or cyanidation, and gravity separation or mercury amalgamation are used to recover the above categories.
In actual production, molybdenum ore separation methods include gravity separation, magnetic separation, flotation, etc. Depending on the type and nature of the ore, different mineral processing methods and processes are required. Since molybdenum ore has good floatability, it is mainly processed by flotation method, and flotation reagents are the key to flotation technology.
When choosing a separation method for antimony ores, it is necessary to consider the physical and chemical properties such as ore type, mineral structure and composition, and also consider the content of valuable components in the ore and the economic benefits of mineral processing. The antimony ore beneficiation methods commonly used in actual production are mainly divided into hand selection, gravity separation, heavy media beneficiation and flotation processes.
At present, iron ore is mainly poor in fine impurities. It is difficult to obtain the ideal iron concentrate grade using a single beneficiation method. Flotation is often used as the main method, and magnetic separation and gravity separation are assisted to form a combined beneficiation process. Flotation is mainly used to reduce the SiO2 content in the concentrate to improve the grade of iron ore.
