Common Types and Applications of Screening Equipment

There are many classification methods for  screening equipment , which can be classified according to the motion track and transmission mode, or classified according to their use. According to its structure, working principle and application, it can be roughly divided into : Screening Equipment Types Motion Track Maximum Feed Size/mm Application Static grizzly Static 1000 Pre-screening Cylinder screen The cylinder rotates in a certain direction. 300 Ore classification, desliming Roll screen The screen roll rotates in a certain direction. 20 Pre-screening, bulk mineral screening, de-intermediation Shaker screen Approximate straight line 50 Classification, dehydration, desliming Round vibrating screen Circle, ellipse 400 Classification Linear vibrating screen Straight line,   Quasi line 300 Classification, dehydration, de-intermediation Resonant screen Straight line 300 Classification, dehydration, de-intermediat

Summary of Gold Cyanidation Methods

图片
Since the gold rush in the 1970s, gold mining has been popular all the time. With the depletion of easily separated gold resources, the modern  gold extraction equipment  and technology is developing towards the extraction of gold from refractory gold deposits. At present, the most commonly used gold extraction method is gold cyanidation. More than 80% of the gold mines use gold cyanidation method to extract gold. What are the methods for gold cyanidation? What's the difference among these methods? What kind of ore can be gold cyanidation used in ? Now let’s take a look at the commonly used gold cyanidation methods. Commonly used gold cyanidation methods include carbon in pulp ( CIP ), carbon in leaching ( CIL ), pool leaching and  heap leaching . Though there is only one word difference literally between them, there are huge differences in the actual process. The pool leaching method is more suitable for ore that has a certain degree of oxidation and requires a longer le

How Many Things Do You Know About Flotation Process?

In the process of analyzing the ore properties, if the mineral disseminated grain size is found to be extremely fine and the physical and chemical properties of the mineral surface are highly different, flotation process is the perfect separation method. The flotation process is a  mineral processing technology  with a wide application range and strong adaptability,and the finest particle size flotation can process can reach 5~10μm. Flotation process can be applied to almost all kinds of minerals such as non-ferrous metals, rare metals and non-metals. It can be used in the processing of more than 100 kinds of minerals, especially for gold extraction. At the same time, the flotation process is also a relatively complex mineral processing process, and there are many factors affecting the flotation effect,such as ore size, ore properties, pulp pH and reagent. The basic theoretical knowledge of the flotation process flow is described below, along with a brief description of the opera

How Much Do You Know About the Routine Maintenance of Magnetic Separator?

Magnetic separator  is the necessary equipment for the separation of magnetic minerals. During magnetic separator, the ferromagnetic materials in the candidate area are suck by a magnetic system to surface of the magnetic drum. As rotating with the drum out of the magnetic area, they will be recovered into magnetic concentrate under the impact of gravity and washing water. In order to ensure the recovery rate of magnetic separator, which is inseparable from the stability and safety of the equipment,it is necessary to ensure the stable and safe production of magnetic separator.The routine inspection is a must-have thing, including daily inspection,regular maintenance, lubrication system inspection, and daily cleaning operations. 1. Daily Inspection of  Magnetic Separator  (1) Check the bolt fasteners of magnetic separator on a daily basis to see if there’s rusting. (2) Check the temperature of bearings,reducer and motor to ensure the temperature of each part is within a rati
