What is Tailing Reprocessing Method?

Although the content of useful components in tailings is relatively low, using the advanced and reasonable mineral processing technology to reprocess tailings can also recover the useful components in tailings to a large extent, so as to fully recover and utilize resources, reduce the output of final tailings and relieve the pressure of tailings on the environment. At present, the common tailings reprocessing methods mainly include:

1. Adopting the froth flotation method to treat the tailings containing hard boracalcite, zinc oxide, apatite

Due to the development of new flotation reagents and froth flotation processes, some tailings produced by the simple mineral processing processes, especially the old tailings, can be recycled to obtain the concentrate products by the froth flotation and method.

2. Using the new gravity separator to recycle the fine mineral in tailings

After the improvement, many gravity separators can be used in the fine and ultrafine tailings reprocessing, such as vertical centrifugal concentrator, shake table with the compound force field, the centrifugal machine with the compound force field.

3. Using the microbial treatment and leaching method to treat the tailings

This tailings disposal method mainly uses the biochemical action of microorganisms to improve the tailing properties and extracts the harmful metal ions in the tailing by means of microbial leaching or microbial mineralization, so as to avoid the environmental pollution.

Guide of Gold Processing Equipment

图片
  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 cyanide leaching.

Common Problems and Solutions of Jigging Process

图片
  Jigging process  has the advantages of good separation effect, large processing capacity, wide separation granularity range, less investment, low production cost, simple process system, etc., so it is widely used in the  gravity separation  process. As an important equipment in the gravity separation process, the operation of jigger is directly related to the product quality and the economic benefits of the concentrator. In case of abnormal problems of jig, which may affect the normal work of the subsequent process flow, it should be dealt with in time. Therefore, it is very important to understand the common problems of the jigging process and how to deal with them. Here are some common problems of jig in the jigging process and their solutions. 1. The screen plate is loose or broken During the jigging process, if the screen plate bounces with the pulsating water, the screws of the screen plate are loosened or dropped. If a column of water appears at a certain part of the bed during

Seven Common Froth Flotation Processes and Their Applicable Conditions

图片
Froth flotation   process is a kind of mineral processing technology that uses the flotation reagents to separate the ore according to the physical and chemical properties of the surface of the ore. The froth flotation process is to grind the mineral to the floating requirement, adjust the pulp concentration and add the flotation reagents, then inflate the air to make the mineralized froth separate. What are the common froth flotation processes? Do you know the application condition of the froth flotation process? 1. Preferential froth flotation process The preferential froth flotation process refers to float a kind of mineral first and inhibit another kind of mineral when the polymetallic mineral contains two or more kinds of useful components, and then activate and float other kinds of mineral. This process that recycles the useful minerals in turn is the preferential froth flotation process. Applicable condition: Generally, the preferential froth flotation process is
