Manufacturer of lead-zinc ore selection equipment

Manufacturer of lead-zinc ore selection equipment

According to the general production situation of lead-zinc ore beneficiation plants, the equipment configured in the lead-zinc ore beneficiation process includes crushers, ball mills, flotation machines, thickeners, dryers, etc. The large stones in the crusher are generally roughly crushed using a jaw crusher, and finely crushed using a hammer crusher; Ball mills are mainly used for grinding, and lead ore needs to be ground again; The flotation machine is a key equipment produced by China and Germany. It has high sorting accuracy, large processing capacity, and a unit volume processing capacity of 2-3 times that of traditional flotation machines. It covers a small area, saves infrastructure investment, and has low operating costs; The thickener and dehydration drying equipment are also equipped with high-performance equipment. Manufacturers of lead-zinc ore equipment can design lead-zinc ore beneficiation processes for free according to user needs.

The entire lead zinc ore beneficiation process provided by the lead zinc equipment manufacturer adopts flotation method, and the lead zinc separation adopts the method of selecting lead first and then zinc. The lead coarse concentrate needs to be ground before the beneficiation process. Generally speaking, lead zinc raw ore needs to undergo crushing, grinding, rough selection, and flotation. Among them, the crushing adopts a two-stage closed circuit process; Closed circuit grinding is adopted for grinding, and lead coarse ore is grinded again; Lead flotation adopts one flotation with three sweeps, and coarse lead ore is further ground three times; Zinc flotation adopts a one coarse, three sweep, and four fine process; After concentration and drying, lead zinc concentrate can be obtained.

The lead zinc ore crushing and grinding process is recommended by the lead zinc ore equipment manufacturer:

The grinding process that has been put into operation in the lead-zinc concentrator is as follows:;

1. Second stage - closed circuit crushing - single stage ball milling

2、 Three stage open circuit crushing - single stage ball milling

Three stage open circuit crushing - rod mill, ball mill

4. Three stage closed circuit crushing - single stage ball milling

5. Third stage - closed circuit crushing - second stage ball milling

6. New Third Stage - Closed Circuit Crushing (or Fourth Stage) - Closed Circuit Crushing - Second Stage Ball Milling

In the crushing process of lead-zinc ore equipment, the two-stage closed circuit crushing single-stage ball milling process is commonly seen in small lead-zinc selection plants with a production scale of 500 days and a processing capacity of less than t/d. At present, three-stage crushing is the most commonly used crushing process in the selection of large and medium-sized factories. The particle size of crushed products is fine, usually up to< 15mm, thus improving the grinding efficiency to a certain extent.

The three stage one closed circuit crushing ball milling process for selecting lead-zinc ore equipment refers to the crushing and grinding process composed of a heavy-duty spring cone crusher or hydraulic cone crusher and a dual axis heavy vibrating screen. The crushing particle size of this process is 6mm, achieving the substitution of crushing for grinding

The combination of lead zinc mining equipment and grinding equipment is mainly a combination of spiral classifier and grinding machine in small factories. When the grinding particle size of large and medium-sized factories is thick, a combination of grinding machines and spiral classifiers is generally used. When the particle size of ore dissociation is fine and two stages of grinding are required, the equipment combination for grinding operation is the combination of grinder high weir spiral classifier/submerged spiral classifier or mill high weir classifier/Hydrocyclone. By separating the return sand of the spiral classifier and the underflow of the Hydrocyclone, the continuous balance of the first stage grinding is obtained, and the grinding circuit is optimized.

Due to the large proportion of lead zinc ore, its hardness is small, and it is easy to overgrind. In order to improve grinding conditions and increase beneficiation recovery rate, 40% of customers adopt stage grinding and stage selection of other process flows. By adopting this process, it is possible to avoid the overgrinding of coarse embedded minerals caused by the single unit dissociation of the ore during one-time grinding.

In the grinding circuit of lead-zinc mining equipment, independent flotation cells are used to flotation high-quality materials, reducing the amount of material entering the second stage of grinding, avoiding overgrinding of ore, and improving the production capacity of the second stage of grinding. Add flash flotation operation between the first and second stages of ball milling to extract qualified concentrate accounting for 1/6 of the total concentrate in advance, and improve the selective recovery rate.

The lead zinc flotation process is recommended by the lead zinc equipment manufacturer:

1. Priority flotation process: This process is mainly used for lead zinc sulfur ores. In principle, lead, zinc, and sulfur are flotation sequentially. The process has strong adaptability to changes in ore grade, high flexibility, and is more suitable for high grade raw sulfide ore.

2. Full mixed flotation process: This process is suitable for treating ores with low total sulfide mineral content, close symbiosis, complex structure, and fine embedded particle size. The characteristic of this process is beneficial for grinding and energy-saving. However, the problem of mixed concentrate drug removal has not yet been well resolved.

3. Partial mixed flotation process: When the grade of copper or lead in the raw ore is low, this process is often more economical.

4. Waiting for flotation process: when Sphalerite is easy to float or difficult to float in ore, lead or copper lead flotation processes can be used to achieve better selection effect. This process not only maintains the advantages of full flotation, but also the floatation of useful minerals is not affected by inhibitors and can be completely floated, and overcomes the defect of difficult separation of lead and zinc in the Copper(II) sulfate activated full flotation process.

5. Branch rate separation process: For mines with poor raw ore grade, the transformation process has many advantages. Specifically, the grade of the raw ore can be increased by itself. The fine particles in the slurry that are difficult to select can be floated by the coarse particle easy to float product (foam) with high floating speed as the carrier, or the residual drug in the former foam product can be used to reduce the dosage of the latter drug. All roughing foam products can be concentrated in the latter kind of cleaning treatment or speed scraper.

Flotation capture agents: 25 # black powder and 31 # black powder. The second is ethyl sulfur nitrogen, aniline black medicine, sodium butyrate black medicine, etc. The foaming agent can also be selected as 2 # pine alcohol oil, such as concentrated 70 # oil, cresol, and phthalein oil.

The beneficiation process indicators for zinc concentrate are 35% -38%, with some reaching 40%. The average recovery rate is about 68%, with a maximum of 73%. The dosage is 10% -12kg/t, with a maximum of 20kg/t of raw ore.

Power consumption of lead-zinc ore dressing equipment used by ore dressing plants of different production scales:

Processing 500 tons of power per day, approximately 600 tons kw

1000 tons of power, approximately 12000 tons kw

Processing 2000 tons of power per day, approximately 23000 tons of kW

Daily processing of 3000 tons of power, approximately 34000 tons kw

5000 tons of power, approximately 45000 tons kw

The lead-zinc ore gravity separation production line launched by lead-zinc ore equipment manufacturers is mainly designed for low-grade lead-zinc ore production line configuration. Its production cost is extremely low, mainly used for pre concentration and enrichment of low-grade lead zinc ore. Of course, the final concentrate can also be obtained directly. Its emergence is to solve the problem of no economic value in direct flotation of some low-grade lead-zinc ores. After treatment by the lead-zinc ore gravity separation production line, low-grade lead-zinc ores can greatly discard waste rocks, play a role in pre concentration and enrichment, and then enter the flotation process for purification, which can greatly reduce beneficiation costs and fully recover and utilize the original low-grade ores without mining value.

The working principle of selecting lead-zinc ore equipment for the gravity separation production line:

The beneficiation principle of the lead-zinc ore gravity concentration production line is based on the working principle of the skip machine. Lead zinc ore mostly exists in the form of coarse particles embedded. After crushing, the lead zinc ore crystals are separated from the gangue and then enter the skip machine for sorting. In the vertical alternating water flow formed by the skip machine, the lead zinc ore and gangue will be re layered in proportion and discharged separately from the machine, ultimately obtaining lead zinc ore concentrate and tailings. Mechanical equipment such as crushers and dewatering screens have collaborated with skip machines to form a lead zinc ore production line.

The lead zinc ore gravity concentration production line is different from traditional lead zinc ore beneficiation production lines. It is a low-grade lead-zinc ore beneficiation production line redesigned according to market demand. It can effectively solve the problem of low-grade lead-zinc ore beneficiation and is an ideal choice for low-grade lead-zinc ore beneficiation. Large processing capacity, high recovery rate, and extremely low beneficiation cost. Suitable for pre concentration and enrichment of low-grade lead-zinc ore, and can also be used to directly obtain the final concentrate.

The lead-zinc ore gravity separation production line provided by the manufacturer of lead-zinc ore equipment has the following characteristics:

1. Lead zinc mining equipment has a high degree of automation, fewer personnel, and low labor intensity.

2. The design of the lead-zinc ore beneficiation process is simple, the equipment configuration is reasonable, and the production cost is extremely low. The average processing cost per ton of raw ore is less than 5 yuan.

3. Adopting the principle of gravity beneficiation, it does not use any chemical substances and does not pollute the environment.

4. The lead-zinc ore equipment has strong applicability, almost applicable to all kinds of lead-zinc ores and Galena.

Lead and zinc mostly exist in the same ore body, and the selection of lead and zinc generally constitutes a joint venture. The former Chief Engineer of China's Nonferrous Metals Industry has an annual processing capacity of approximately 10 million tons of lead-zinc mines (which is not the entire territory of China). The annual production of lead and zinc concentrate is nearly 600000 tons. In recent years, mining technology has significantly improved. The beneficiation process and main technical and economic indicators of the lead-zinc equipment have reached the Vanguard International Semiconductor Corporation level. The flotation process of polymetallic sulfide ore has developed greatly; The new process of high alkalinity flotation and the asynchronous priority flotation of mixed concentrate have been successfully applied in production; The proportion of lead-zinc factories using cyanide free processes has exceeded 40%; New progress has been made in the beneficiation of oxidized lead zinc ore, which is suitable for complex mineral composition, fine embedded particles, and large mud content; The newly developed aniline black drug has advantages such as strong capture power, good selectivity, and low toxicity; The grinding and dosing processes of key mineral processing have achieved microcomputer control.

Lead and zinc mining equipment manufacturers scientifically design lead and zinc mining technology and equipment selection based on on-site investigations and characteristics of lead and zinc mining. According to the physical and chemical properties of different minerals in the ore, gravity separation, flotation, magnetic separation, electrical separation, magnetization baking, etc. are adopted.; The selection of lead-zinc mining equipment fully reflects the significant characteristics of design rationality, effectiveness, applicability, large processing capacity, low wear and tear, and low operating costs.
