Beneficiation technology
Gold flotation line
[Process introduction] : Flotation is one of the most widely used beneficiation methods to treat rock gold ore in gold concentrator, which is often used to treat sulfide mineral gold-bearing ore with high floatability. The flotation process can enrich gold to the maximum extent in sulfide minerals, the tailings can be directly discarded, and the dressing cost is low. 80% of rock gold mines in China are sorted by this process.
[Application] : Gold flotation process is suitable for the treatment of sulfide gold-bearing quartz vein ores, polymetallic gold-bearing sulfide ores and carbon-bearing (graphite) ores with finer gold grains and high floatability.
Beneficiation technology of silver ore
[Process introduction] : In order to improve the recovery rate of independent silver ore flotation, Xinhai improved the silver ore beneficiation process through three ways: First, according to the thickness characteristics of silver mineral distribution particle size, silver minerals were fully dissociated as far as possible to improve the recovery rate of silver; The second is to choose neutral or weak alkaline flotation pulp basicity and choose sodium carbonate as flotation pulp adjustment agent to improve the floating property of silver; The third is to use xanthate and black medicine together to enhance the harvesting ability of silver.
[Application] : Silver ore dressing process is mainly used to recover silver and associated metal minerals, silver-bearing ores are mainly divided into silver and gold ores and lead, zinc and copper associated ores two categories.
Beneficiation technology of copper, lead and zinc ore
[Process introduction] : Copper, lead and zinc mineral processing process adopts mixed flotation - concentrate regrinding process, which can reduce grinding costs and is easy to manage, and the application of new non-toxic flotation agents, high efficiency and environmental protection.
[Application field] : The process of mixed flotation and concentrate regrinding is generally suitable for copper, lead and zinc sulfide ore with close symbiosis, difficult dissociation and uneven distribution size.
Molybdenum ore processing technology
[Process introduction] : Regrinding and resorting of coarse concentrate to improve concentrate index; According to the specific properties of ore, concentrate regrinding process is selected for sorting; Energy consumption is reduced by 30% and recovery rate is increased by more than 10%.
[Application] : Molybdenum ore dressing production line can be applied to single molybdenum ore or refractory molybdenum ore with complex ore properties, close symbiosis with sulfide minerals and finer particle size.
Hematite beneficiation technology
[Process introduction] : Hematite is a kind of weak magnetic iron ore, and there are many beneficiation methods used. Traditional beneficiation methods include roasting magnetic separation, flotation and high intensity magnetic separation, but the index of a single process is poor. According to the characteristics of hematite beneficiation process, it can be divided into roasting magnetic separation process, flotation process, weak magnetic-strong magnetic separation process, strong magnetic flotation separation process and heavy magnetic-float combined process.
[Application field] : Hematite beneficiation process can be applied to hematite and impurities with uneven particle size and fine grade content, including a small amount of magnetite, gangue minerals contain quartz, kaolin and other ore properties of more complex hematite.
Magnetite beneficiation technology
[Process introduction] : Magnetite is a strong magnetic mineral, so the separation process based on low intensity magnetic separation is generally adopted in magnetite beneficiation.
[Application field] : Magnetite beneficiation process is suitable for the treatment of iron ore with magnetic minerals.
Beneficiation process of phosphate rock
[Process introduction] : According to different phosphate ore properties, phosphate ore dressing methods include flotation, scrubbing and desliming; Gravity separation, chemical leaching, combined beneficiation; Photoelectric sorting, magnetic cap method, etc. Flotation is the most used phosphate ore processing process, including direct flotation, reverse flotation, reverse flotation and double reverse flotation.
[Application field] : Phosphate rock flotation equipment production line can be applied to phosphate rock with complex ore structure, complex mineral occurrence relationship, small particle size, close Mosaic relationship, common hybrid symbiosis, and difficult monomer dissociation.
Graphite ore processing technology
[Process introduction] : Crystalline graphite has natural floatability, so Xinhai mainly uses flotation method to separate graphite ore. Flake graphite has good floatability, so it is mostly separated by flotation method. For graphite ore with a variety of gangue, the combined process of gravity separation and flotation can also be used.
[Application field] : Graphite ore sorting process is mainly suitable for various graphite ores with different crystal forms and graphite ores accompanied by silicate minerals such as mica or pyrite.
Dry discharge of tailings
【 Process introduction 】 : The final tailings water content is less than 15%; Save more than 2 yuan/ton than the traditional process system; The service life of the equipment is 2 times that of the traditional process, and the maintenance cost is low. The application mine has been rated as "green mine" for many times.
[Application field] : The tailings dry discharge system is mainly used for the concentration and dehydration process of tailings in the concentrator to achieve the purpose of tailings dry stacking, so as to avoid environmental pollution, and is the preferred process for the implementation of green mines.
Tailings rebeneficiation process flow
[Process introduction] : The tailings reprocessing process is mainly from the perspective of protecting the environment and making full use of resources, and all kinds of metal and non-metal tailings with reprocessing value are reselected. According to the different properties of each tailings, a reasonable tailings reprocessing process is designed to fully excavate the value of tailings.
[Application field] : The tailings reprocessing process is suitable for the reprocessing of various metal and non-metal tailings, including iron, gold, lead zinc, copper, fluorite, tungsten, phosphorus, graphite, bauxite tailings, etc.

What are the main contents of mineral processing tests?
The laboratory small-scale process test is the basic experiment of the mineral processing process test. Generally, mineral processing tests start with laboratory small-scale tests and then gradually expand in scale. The content of each stage of the test is determined according to the purpose of the test.

Basic characteristics of primary grinding
Grinding needs to be based on the selection requirements and the combination of grinding machines. It is generally divided into one-stage, two-stage and multi-stage grinding processes according to the number of grinding stages. The one-stage grinding process usually constitutes a closed loop, and the ore is directly fed into the grinding machine. The most suitable particle size for feeding is generally 6

Classification work in the grinding and classification process
Grinding and grading is a subsequent process after crushing and screening within the scope of ore preparation. The position and function of this grading operation in the process are divided into 5 types. 1. Pre-grading Pre-grading is generally not used before the first stage of grinding, but only after the first stage of grinding.

Importance of tailings disposal
Tailings are the products with the lowest content of useful components discharged from mining production. They are stored in tailings ponds for a long time. Not only do they occupy a large amount of agricultural and forest land, but they also cause the local land resources to lose balance. Because tailings contain a large amount of toxic substances
