Gold is the special currency for the investment and reserve, and it is even an important industrial raw material for jewelry, electronics, aerospace and other industries. With the rapid development of industry and finance, the gold processing has been paid close extensive attention and developed rapidly. With the decrease of the ore grade, the demands for gold ore dressing technology is increasing gradually. In recent years, new process, new technology and new equipment are constantly being applied in the gold ore processing, which promotes the gold ore dressing process and production index. Xinhai has been committed to the research and development of gold ore dressing technology and equipment for 20 years and possessed rich project experience, who can provide you with reliable equipment and technical services. Let’s see Xinhai by combining the following several common gold ore dressing processes. 1. Gravity Separation Due to the large proportion of gold ore, gravity separatio...

Y - Ball valve   is the specialized equipment to change the flow direction of materials in materials transport system. It controls the closing and opening of the oil ports to decide the materials flow direction by changing the spool position with wide application in mine industry. In the process of material transportation, people usually adopt double pumps double pipes in order to ensure the dressing plant normal working and avoid accidents. One pump as backup, the other pump keeps working. But when people want to switch the pump, they need to switch the two valves to complete operation which usually leads to blockage and stopping production. In recent years, the unblocking   Y - ball valve   becomes popular developed by Xinhai wear – resistant rubber company. The valve does not need manual control, which push the spool to the other pipe sport by the slurry pressure. By this way, the valve solves the blockage problem. The specialized design   Y - ball  ...

Agitation tank is widely applied in mine fields and a kind of necessary equipment in dressing plant. There are many brands of agitation banks in the market, and the clients do not know how to choose and which one is the most suitable. This article will show you a full and systematic introduction of the agitation tank 1. The uses of agitation The main function of agitation tank is to mix materials. What is the purpose of mix materials? 1) A mixture of two or more kinds of liquid, in order to obtain a uniform mixed liquor 2) Dispersion and mixing two or more immiscible liquids, in order to obtain emulsion 3) Mixed gas and solution 4) The solid particles suspended in solution ...

There are rare native   copper   deposits but abundant copper tailings in China. According to incomplete statistics, hundreds of millions of tons of copper tailings are discharged every year in China, which are increasing year by year. Copper tailings include little copper, silver, zinc, lead ore, but a large number of silica-aluminate tailings, such as calcite, plagioclase and diopside. Generally, complex copper ore composition and outdated mineral processing technology and equipment lead to the different copper content in copper tailings. The large number of copper tailings that are not fully utilized not only occupy areas, but also cause serious environmental pollution. Therefore, it is necessary for economic benefit and environmental protection to study the secondary utilization of copper tailings and develop circular economy. The characteristics of copper tailings composition in China are the high grade of copper, fine grain size, various types and complicated co...

In modern ore dressing, cone crusher has become a kind of crushing equipment with a wide range of application, its higher crushing ratio, low energy consumption and even product granularity make it suitable for crushing medium hardness ore, so it is widely applied in secondary and fine crushing of all kinds of ferrous and non-ferrous metals, which effectively reduces the grinding granularity, achieves more crushing less grinding result, at the same time, it also improves the ability of ball mill, then improves the economic benefits. In the daily operation, cone crusher inevitably has some disadvantages due to long time use and equipment factor, which affect the normal production. Therefore, Xinhai technicians have made an in-depth discussion on shortcomings of cone crusher, and strived to provide the best   crushing equipment   for our customers. Here we introduced four big problems of cone crusher and relative measures. 1. Unreasonable anti-dust device.   The du...

In the process of modern ore dressing,   vibrating feeder   is one of the most admired feeding equipment. As a new energy-saving feeding equipment, vibrating feeder can evenly and continuously send blocky or granular materials to crushing equipment and screening equipment, so as to achieve the purpose of ration feeding. In addition, vibrating feeder can also screen materials roughly, which greatly improves the crushing efficiency. At present, there are many types of vibrating feeders in ore dressing market. As the leading manufacturer of mineral processing industry, Xinhai always be at the forefront of mineral processing technology and equipment, it has successfully developed a series of feeding equipment to meet different user requirements, especially its   ZSW vibrating feeder   is favored by many customers with unique advantages. High efficiency and Low Operating Cost Xinhai adopts eccentric shaft vibrator with linear vibration and stable amplitude, which n...

Copper ore is a kind of high-grade sandy copper ore concentrate. It is widely used in casting, forging, metallurgy, paving, heat treatment, steel structure, space truss structure, ships, bridges, mines and so on, which encourages the increasing development of copper ore manufacturer and copper ore dressing equipment manufacturer. Copper ores are divided into black copper ore and   white quartz sand . The black copper ore is featured with 30% iron, 7 Moh’s hardness, 2.0 g/cm3 density and 800 ℃ melting point. Most black copper ore producers in China are located in Yunnan province. Brown copper ore is mainly used in rust cleaning, sand removal, strengthening, forming, stress relieving, surface cleaning and coating, stone cutting in the casting, machinery and other fields. White quartz sand is featured with 7 Moh’s hardness, 2.3g/cm3 density. The white quartz sand manufacturers are mainly distributed in Zhejiang province. What’s more, white quartz sand is mainly used ...

Origin of World Consumer Right Day With the rapid development of modern industrial production and the innovation of production technology, consumer goods is growing in frequency and the consumption structure is more complex, which lead to all kinds of consumption accidents and problems, then cause serious infringement on consumers’ rights. In order to deal with these problems, the first consumer organization was established in the United States in 1898. Then the National Consumer Union was established in 1936. After the Second World War, various organizations that reflect consumers’ interests and demands appeared in some developed countries. On this basis, International Organization of Consumers Unions was founded in 1960. Since then, consumer movement has become more active, and many developing countries also established their consumer organizations, which was a global phenomenon. At present, more than 300 consumer organizations are engaged in activities in over 90 countries. O...
