Tailings are waste produced after mineral processing. In the early days, due to limited mining technology and lagging mineral processing equipment, some useful minerals remained in the tailings. If these minerals are effectively recovered, it is an effective way to improve mineral utilization. Tungsten ore is no exception. Currently, there are many technological methods for re-selecting tungsten tailings, such as flotation, gravity separation, magnetic separation, etc., which are all effective separation methods. However, the selection method depends on the composition of the ore and the characteristics of the tailings. Let’s take a look at these tungsten tailings reselection methods.Details>>
In the early days, due to backward mining technology and process plans, some useful minerals were lost with the tailings, resulting in a waste of mineral resources. Copper mines are no exception. The chemical composition of copper minerals after becoming tailings is relatively complex, and the minerals will contain A large amount of silicon, sulfur, calcium, aluminum, iron and other valuable elements have certain mining value. Therefore, copper tailings need to be re-sorted to recover them and promote the comprehensive utilization of copper.Details>>
"Lucid waters and lush mountains are invaluable assets" is an important concept for the sustainable development of Woguo Mine. The ore sorting process will have a great impact on the original mine and the surrounding environment. For example, iron ore, as we all know, has large resource reserves and large output. After mining, the goaf area of the original mine is prone to collapse; the tailings after mineral processing have large output, occupy a large area, and are prone to dam collapse. These are all irreversible hazards. But during the development process, the tailings are recyclable. At present, there are three main methods for iron tailings treatment in my country: one is to re-select and recycle valuable iron tailings; the other is to dry discharge the tailings and screen out useful factors to make construction materials; the third is to use iron Tailings fill the goaf.Details>>
According to the different mineral properties of iron tailings, the selected tailings re-selection methods are also different. Generally speaking, magnetic separation, flotation and gravity separation are the commonly used methods for iron re-selection. In addition, generally iron tailings have Due to the characteristics of fine particle size, if a certain process is used alone, the ideal iron concentrate may not be obtained. It needs to be achieved through several joint beneficiation processes. Let’s talk about the process of re-selecting iron tailings.Details>>
Iron ore is a mineral resource with a large output among metal minerals. The tailings stored after mineral processing also occupy a very large area and require a lot of manpower, material and financial resources to manage. In addition, some iron tailings contain harmful substances such as heavy metals and the dust caused by fine tailings particles will have a serious impact on groundwater resources and the surrounding environment. If the tailings are treated, the above problems can be effectively improved. At present, Xinhai Mining has developed a tailings dry discharge process, which is a way of tailings storage. Let’s learn about the advantages of iron ore tailings dry discharge, what is the process, and what equipment is used. ?Details>>
Recycling of iron tailings is an important method to reduce the hazards of tailings. Not only can it reduce the use of iron tailings ponds or reduce the area occupied by tailings ponds, but it can also effectively solve the various hazards of tailings piles. At present, the common methods for recycling iron tailings mainly include tailings re-selection, tailings dry discharge, tailings backfilling and tailings production of other materials.Details>>
Iron tailings re-selection is an effective way to recover iron. With the gradual reduction of rich iron ores, the development of lean iron ores and iron tailings re-selection have entered people's field of vision. For tailings recycling and re-selection, it is necessary to understand the mineral composition of iron ore. Select a suitable iron ore tailings re-selection process based on the properties of the ore. Currently, the common iron ore tailings re-selection processes mainly include magnetic separation, gravity separation, flotation and combined beneficiation processes.Details>>
Dry tailings discharge is one of the methods of tailings treatment. The process is relatively safe and environmentally friendly. Dry tailings discharge reduces environmental pollution, dam collapse and other hazards caused by direct tailings discharge. In addition, the tailings after dry discharge occupy a small area, and the tailings water can be returned to the factory for reuse, which not only reduces the risk index, but also saves water resources. However, depending on the nature of the tailings, the water content and the needs for utilization of tailings resources, the applicable tailings dry discharge processes are also different. At present, there are 6 commonly used tailings dry discharge process solutions in mineral processing plants. Let’s take a look at them below.Details>>
As more and more gold mines are mined, recoverable gold resources are becoming less and less, and the development of gold tailings has turned. However, for the development of gold tailings, there are requirements for the gold content. Generally, the content per ton reaches more than 0.3g, which has recycling value. However, some gold tailings that have been recently developed or have no development value can be recycled through the tailings. The filling process of the glue industry can reduce the pollution of the surrounding environment caused by tailings storage and the harm of dam failure, etc. Let’s take a look at the requirements and processes of the gold mine tailings cementing and filling process.Details>>
The comprehensive recovery of gold tailings mainly includes two concepts. One is that gold tailings are re-dressed as secondary mineral resources to obtain useful components for recycling. The other is that gold tailings can be used according to the differences in tailings composition. It is used in the production of concrete aggregates, cement, floor tiles, wall tiles, ceramics, glass, foam glass and other building products or goaf filling materials. If gold tailings exist and have recovery value, it is necessary to conduct a second re-election.Details>>

Tailings are "waste" produced by mineral processing plants. However, due to the backward technology of early mineral processing, some useful minerals will be discharged with the tailings, resulting in a waste of resources. Nowadays, innovative technologies can be used to reprocess this type of tailings and recover useful minerals. This article takes a certain gold tailings re-selection of iron resources as an example to introduce the tailings re-selection process.Details>>
