What is the beneficiation process of glass sand washing plant ? The beneficiation process of 15 tons per hour glass sand production line is "raw ore-pre-screening-medium magnetic separation-scrubbing-desliming-coarse-grained classification-desliming-plate magnetic separation-high magnetic separation-fine-grained classification-dewatering" to produce wet quartz concentrate. Glass sand washing plant Which quartz sand ore is suitable for making glass? Material suitable for mineral processing in glass sand production line: SiC, mullite, limestone, barite, potassium albite, wollastonite and dolomite Which equipment should be used in glass sand washing plant? Supporting products: scrubber, plate magnetic separator, obstructed settler, hydraulic classifier, dewatering screen, desliming bucket What are the advantages of glass sand production line? 1. High purity and pollution-free Reasonable process and equipment are adopted, which greatly saves power consump...

Wheel sand washing machine and spiral sand washing machine   are two kinds of common sand washing equipment. In the process of sand production, sand washer is an indispensable equipment. Sand washer is a washing equipment for sand (artificial sand, natural sand). It can remove impurities covering the surface of sand and stone, and destroy the vapor layer covering sand, so as to facilitate dehydration and play a highly efficient role. Sand washing can improve the quality of products. But some friends don't know about the two devices. Here are two kinds of sand washers for you to compare and explain. 1. Wheel sand washing machine Wheel sand washing machine is a washing equipment for artificial sand (including natural sand). Mainly used in construction sites, sand and stone factories, transportation, chemical industry, water conservancy and hydropower, water concrete mixing station, mining, building materials for sand washing, classification and dehydration industries. Sand wash...

Ore dressing and purification of silica sand is mostly aimed at removing iron. The methods of removing iron can be generally divided into physical-mechanical method, chemical method and microbial method. Physical-mechanical methods, such as magnetic separation, gravity separation, flotation, ultrasonic mineral processing and water washing, are suitable for the treatment of coarse impurities. Chemical method is to leach with inorganic acid and remove iron oxide film on fine iron-titanium minerals or quartz particles by chemical reaction. Although this method has high efficiency, it also has high cost, harsh technical conditions and harmful to the environment. There are also microbial beneficiation methods, which are used to separate iron from oxidized ores by various bacteria. The process is slow and industrialization is still difficult at present. The quartz sand raw ore situation is different, the method used is also different, below we will introduce in detail. 1. Water elution an...

After magnetic separation , the impurities of silica sand have been removed mostly, but some of them can not be removed by magnetic separation. Flotation （ Flotation machine ）is the most important step to remove impurities after magnetic separation. If the impurities of silica sand are not cleaned up, the role of silica sand will be greatly reduced. flotation machine 1. When feldspar is abundant in silica sand, PH of pulp is adjusted to 7-8 using fatty acid as collector. After flotation of iron-bearing materials, feldspar is flotated with hydrofluoric acid and amine. Finally, when the pulp PH is 7-8, ammonia is used as collector to flotation silica. 2. Pulp PH was adjusted to 7-8 and sulfonated petroleum was used for flotation of iron ore. 3. Use amine as collector, mix flotation silica and feldspar, add hydrofluoric acid and amine to flotation feldspar when mix concentrate separates, tailings are silica concentrate. 4. Feldspar and silica inclusion flotation is carried...

silica sand should be recycled and reused after the treatment of water quality. Back-cleaning can make the use of silica sand filter material more fully and not waste. The principle of back-cleaning and utilization of filter material is very simple, which is the friction process. 1. Technical requirements for silica sand water treatment. The sum of breakage and wear rate of quartz sand filter material should not be greater than 1.5% (percentage by mass, the same below).  The density of quartz sand filter material should not be less than 2.55g/cm3, except for special requirements for density in use.  Quartz sand filter material should not contain visible soil, mica and organic impurities, and the water leaching solution of filter material should not contain toxic substances. The content of slime should not be more than 1%, and the content of light substances with density less than 2g/cm3 should not be more than 0.2%.  The burning reduction of silica sand should no...

KYF flotation machine and XCF flotation machine are common flotation equipment. They are often used together in silica sand washing plant  processing. What are the characteristics of these two flotation machines and what effect can they achieve when they are used together? Characteristics of KYF Flotation Machine and XCF Flotation Machine KYF flotation machine is a kind of air-filled agitating flotation machine. When the impeller of KYF air-filled flotation machine rotates, the pulp in the tank is sucked from the bottom of the impeller to the blade. At the same time, the low-pressure air supplied by the blower enters the air distributor from the air duct and hollow shaft, and flows into the blade and into the air distributor after the pulp is fully mixed, the pulp is sucked by the blade. The upper half edge of the wheel is discharged, and the discharged slurry moves upward of the syncline. The stator installed above the incline around the impeller stabilizes and directs backw...

1.Application Status of  high purity silica sand  High  purity silica  sand refers to silica sand with SiO 2 content higher than 99.9%, which is chemically stable and insoluble except HF. Other acids, slightly soluble in KOH solution. It is difficult to purify silica sand because of its various impurities, complex occurrence and different distribution. The earliest raw material for producing high purity silica sand is natural crystal, but with the gradual depletion of natural crystal resources, it has become an inevitable trend to extract high purity silica from ordinary silica sand. High purity silica sand is widely used in high-tech industry. In the semiconductor industry, wafers with excellent thermal properties at high temperatures can be made from molten silica o produce high-tech heat pipes with good thermal stability at high temperatures. In the communications industry, silica glass mad...
