How to Decide the Order of Flotation Method for Lead and Zinc Ore?


When the material to be processed by the flotation contains many kinds of components to be recovered, it needs to base on the floating property and the symbiotic relationship to determine the order of the different components to get the products separately. In the production, the flotation process is usually used preferentially in the lead and zinc ore. The following will introduce it simply.

In the practical production, by the different beneficiation order, the processes to be adopted can be divided into four categories that are preferential flotation process, mixed flotation process, partial flotation process and equal flotation process. Preferential flotation process means a process that every component to be recovered in the material will float one by one and then pre-recovery component rich in one will be got finally. Mixed flotation process refers to that all the components in the material will be floated together and the intermediate products having been got will be separated by the flotation. Partial flotation process indicates a process that partial components in the material will be recovered firstly and the rest will be inhibited as well as other components to be recovered will be floated. While equal flotation process means a process that the components to be recovered with similar floatability will be floated together and then separated finally, which is suitable to process the material with components which are partially difficult to float and partially easy to float.

Among the beneficiation orders of the lead and zinc flotation methods, the preferential flotation process is adopted firstly. By the different floatability of the lead and zinc, the lead concentrate with good floatability will be floated firstly and then the zinc concentrate with poor floatability will be floated. Preferential flotation process is suitable for the ore with gangue dotted with less coarse particles. Before determining the mineral flotation order, the techniques of Xinhai ore dressing institute will make an analysis on the sample and put forward reasonable beneficiation process by the beneficiation report. The practice shows that the beneficiation process is advanced and practical which has won the trust of our customers.

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
