Hydrocyclone is an effective separation equipment that carries on two-phase fluid separation by using the centrifugal force field, which is a non-motion separation device composed of the upper cylinder and the lower cone. In the mineral processing, hydrocyclone is mainlyused in the classification of grinding circuit, especially the classification in the fine grinding. Besides, hydrocyclone can also be applied in the desilting and thickening operation. Different applications mean the various requirements for the technical parameters of the hydrocyclone, including structure parameters, operating parameters, feeding properties. All of them are correlated and constrained mutually, each of them is not easy to be adjusted and controlled, so we must understand each technical parameter before choosing the hydrocyclone. 1. Diameter and height of the cylinder The diameter of the cylinder is the main reference point to determine the size of hydrocyclone, which has a certain ratio with ot

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

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

Equipment plays an important role in   magnetite beneficiation process . The traditional permanent magnetic cylindrical magnetic separator has disadvantages, including limited use range, and bad separating effect. New type high efficient wet permanent magnetic cylindrical magnetic separator produced by Xinhai has a large use range and good beneficiation index. In new-built beneficiation plants, it has obvious effect on magnetite beneficiation optimization process. Now, it will be introduced briefly below. All  magnetic equipment  all adopts neodymium iron boron magnet with high energy product and high intrinsic coercivity. Magnetic field intensity is large and has the advantages of extensive magnetic effect. The demagnetizing index is less than 5% for eigh years. To achieve efficient separation from magnetic minerals and non-magnetic minerals, new type permanent magnetic cylindrical magnetic separator adapts large magnetic wrap of the new structure with gradual change field intens

At the early spring of 2019, Xinhai, as the leader and extender of mineral processing turn-key service, combining the technology strength with over 20-year mineral processing experience, declines that the mineral processing EPC service officially updates into   mineral processing EPC+M+O   service. EPC+M+O service aims at providing clients a complete mineral processing turn-key service to solve all the problems about mine operation. Let them free of compliments. 1. What is “EPC+M+O” service? Specifically, Xinhai mineral processing EPC+M+O service is a customized service through the actual condition of dressing plant, also known as one-stop service including dressing plant design and research, a set equipment manufacturing and purchasing, commission and delivery, mine management and mine operation. Design and Research service Including project consultant service,   mineral dressing test , mineral processing flow and equipment selection, processing plant scheme design and produc

As the exhaustion of high-grade gold ore, researching middle-low grade and refractory gold ore and strengthen the traditional   gold processing   undoubtedly have become the main trend in the global gold processing industry. There are three common gold processing methods widely used in many gold processing plants according to the different types of gold ore characteristics and user requirements, includes gold cyaniding process,   gold flotation process , gold gravity separation process. One. Gold Cyaniding Process Gold cyaniding process is a kind of main modern gold processing method that adopting cyanide as the leaching liquid to extract gold from ore or concentrate. The gold cyaniding process can be divided into agitating cyanidation process and leaching cyanidation process. Agitating cyanidation process is applied to treating the tailings after gravity separation, amalgamative tailings and flotation gold-bearing concentrate, or applied to full slime cyanidation. Leaching

As one of the earliest and most widely used metals in the world, iron ore is an important raw material for iron and steel production.   The beneficiation of iron ore   needs a series of processes, including crushing,   grinding ,   magnetic separation , flotation, gravity separation. At present, the iron ore resources are decreasing day by day. The iron ore resources are featured with more lean ore, less rich ore, more associated ore and complex ore composition. There are a variety of iron ores in nature, mainly including magnetite, haematite, limonite, siderite, so the beneficiation of iron ore needs a suitable process to improve the economic benefit. One. Beneficiation of iron ore from magnetite Because of the strong magnetism of magnetite, weak magnetic processing technology is the main processing technology, including: 1. Single weak magnetic separation process The single weak magnetic separation process is suitable for a simple single magnetite, which can be divided
