  With the increasing of copper mining resources, copper tailings emissions increases as well. Copper tailing is made up of the fine sands from copper ore crushing and concentration. There are an amount of metal and nonmetal minerals to be reprocessed. Suitable reprocessing technology can recycle them. It has an important meaning to the comprehensive utilization of copper tailings. In actual production, different types and characteristics of copper tailings need different mineral processing methods. In this passage, we will introduce you the copper tailing physical and chemical properties, and two types of  common copper reprocessing methods : vulcanization flotation and leaching. 1.Copper tailings physical and chemical properties The physical form of copper tailings is similar to sand. However, it has more complex mineral composition than sand. There are a large number of valuable elements such as silicium, calcium, aluminum, iron. The main mineral is quartz, feldspar, calcsp...

  In general, common mineral impurities in silica sand such as feldspar, mica and other silicate minerals, more adopt flotation process for separation, in order to remove the majority of mineral particles outside quartz sand, and enrichment quartz. Due to the difference of water wettability of different mineral surfaces, hydrophobic particles tend to stick to bubbles and rise to the liquid level, while hydrophilic particles will escape from suspension or sink into the water after collision with bubbles, so as to achieve the purpose of mineral separation. The flotation used in the  silica sand processing  can not only remove the mica, feldspar minerals, but also folate the phosphorus, iron and other minerals, and remove the broken and grinding mixed with secondary pig iron. Below, let’s take you to understand in detail how to achieve the flotation separation of mica, feldspar, iron ore and apatite and silcia sand. 01. Flotation separation of mica and silica sand A large nu...

  With the increasing attention of environmental pollution and tailing treatment, tailing processing has become one of the important links in current mineral processing production. The tailings are one of the products of separation operation in mineral processing. Due to the low content of its useful components, the tailings cannot be further separated under the current mineral processing technology and economic conditions. After the ore is ground into the very fine pulp, the ore powder less than 0.075mm generally accounts for 50%-70%, and some of them are even finer, the pulp concentration is generally around 15%-40%. If it is discharged into a tailings pond, there will be a large amount of water in addition to the ore, basically equivalent to a reservoir. The accumulation of tailings can not only cause environmental pollution, but also easily lead to tailings dam break, bringing hidden safety risks. Therefore, how to discharge and stockpile the tailings has become an important pr...

  The  vibrating screen  is a very important auxiliary equipment in the mine production, which will directly affect the normal operation of the production line if the vibrating screen fails. As a common type of vibrating screen, what are common problems of the circular vibrating screen (also known as the round vibrating screen) in the daily operation? And how can we solve them? This paper analyzes the causes of five common problems of circular vibrating screen and puts forward countermeasures. One. The shaft of circular vibrating screen breaks In general, the  circular vibrating screen  is mainly driven by an electric motor with an eccentric mass vibrator to produce vibration. In the vibrating process, the shaft is the key component to drive the vibration of the circular vibrating screen. Therefore, the break of the shaft is a common fault in practical use. Once the shaft failure occurs, the circular vibrating screen will immediately stop working, and its mainte...

  The gold ore has a high mining value, the gold processing technologies are more complex, and the gold processing equipment used is not the same. At present, the common gold processing technologies mainly include the cyanide leaching method, flotation method and gravity separation method. That is, through the crushing, screening, grinding and classification, the ore is sent to the various  gold processing equipment  (leaching agitation tank, flotation cell, gravity separator) for separation. The concentrate obtained by the cyanide leaching, gravity separation and flotation are smelted by the chemical methods, and the product is finally made into the finished gold. Below, we will mainly explain the gold processing equipment used in the different stages of gold processing. One. Gold processing equipment used in the cyanide leaching method Cyanide leaching is one of the main gold processing methods, which can be divided into agitation cyanide leaching and percolation cyanid...

  In mineral processing solution, flotation has a large application. It is complicated. There are many factors influencing flotation technology, including ore characteristics, grinding fineness, slurry concentration, pharmacy system and so on. The  flotation  effect is closely related to these factors. At the same time, the flotation flow solutions are multiple, such as fully mixed flotation, part mixed flotation, asynchronous flotation, and priority flotation. A flotation experiment is essential to ensure the suitable processing condition, to customize reasonable flotation flow, and obtain the ideal recovery result. In the  flotation  experiment, the main content includes mineral processing scheme determination, ensuing the primary and secondary relationship of influencing factors and influencing level, ensuring the ideal processing condition, and ensuring the mineral processing indexes and other technology indexes. Among them, five aspects are important: grind...
