what are the differneces between gold CIP and CIL

Comparison between gold CIP and CIL:
1. The CIP process is longer than the CIL process, but there are a large amount of carbon and a low concentration of carbon in the CIL process, so the slurry volume for carbon transshipment in the CIL process is several times that of CIP (generally four times);
2. There is a large amount of metal backlog in the CIP process, and the distribution of metal backlog in the two processes is different. The distribution of the metal backlog in the CIP process on the activated carbon is basically the same as that in the solution, but in the CIL process, the metal is mainly deposited on the activated carbon. Besides, the amount of gold in the solution also varies.
3. The gold grade in the solution in the CIL process is higher than the CIP process, which is determined by the process structure. The CIL process is composed of leaching and adsorption at the same time. So, the new dissolved gold constantly enters the solution, the gold in the solution is constantly replenished and the gold content in the solution is relatively high. The CIP process is the single adsorption, the complementary quantity of dissolved gold in the solution is very small, so the gold grade is lower.

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
