What Do You Know About Froth Flotation Process?

In the process of analyzing the mineral properties, if it is found that the mineral Mosaic particle size is fine and the physical and chemical properties of the mineral surface are quite different, it is self-evident that the froth flotation process is a good separation at this time. Froth flotation process is a kind of ore dressing technology with wide application range and strong adaptability, and the lower limit of grain size of raw materials can be up to 5 ~ 10 muon. It can be applied to almost all kinds of non-ferrous metals, rare metals and non-metallic minerals, and other mineral sectors. At the same time, the froth flotation process is also a relatively complex mineral processing process, there are many factors that affect the froth flotation separation effect, such as ore size, ore properties, pulp pH and agents. The following will introduce the basic theoretical knowledge of froth flotation process from the main process, and provide simple operation tips.
Froth flotation process including grinding, mixing dosing, froth flotation separation and flotation foam products and tailings after dehydration, in front of the froth flotation operations need grinding ore to the optional size range, generally need to 0.1 mm below the flotation of coarse grinding ore grain (greater than 0.1 mm) due to large weight, can increase ore grain shedding force, very fine grains (usually less than 5 ~ 10 microns slime) of ore grain, because the quality of slime is small, easy to stick on coarse surface, make the coarse flotability is reduced, so the ore grain is too thick or carefully will reduce the ore recovery rate in ore grain too thick, 1)
Collector by collecting force strong, can also be adding auxiliary collector kerosene, diesel oil, etc, to strengthen the coarse grain collecting, increase the adhesion ability of particles and bubbles and fixation strength, reduce loss 2) increasing the mass fraction of pulp, and increase the buoyancy of pulp in the premise of guarantee the stability of foam layer, stirring promotes the coarse grain suspension, appropriately increase and bubbles in attachment opportunity in froth flotation carefully ore grain, 1) using the selective flocculation flotation, the flocculant flocculation agent selectively NingMu mineral particles or gangue fine mud, then using froth flotation separation of 2)
flotation
Carrier flotation, the use of mineral particles of general flotation size as the carrier, so that the target mineral fine particles cover on the carrier floating carrier can be used with similar minerals, can also be used with different minerals for example, can be used pyrite as the carrier flotation fine particles of gold with calcite as the carrier floating away from kaolin fine particles of iron and titanium impurities

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
