Introduction of flotation machine
The flotation machine is important for realizing the flotation process. It is suitable for processing fine-grained nonferrous metals, ferrous metals, non-metallic and rare metal ores, and performs particularly well in the separation of complex paragenetic ores and low-grade ores. Such as copper, lead-zinc, lithium, antimony, fluorite, talc, etc. After the minerals undergo wet grinding, the minerals dissociated into monomers are adjusted into a slurry of a certain concentration. It is sent to the flotation equipment after being fully mixed with flotation chemicals in the stirring tank.
JXSC flotation machine has a large air suction volume and low power consumption. It can realize the selective separation of polymetallic ores such as copper-lead-zinc, sulfur-iron, etc., and can increase the copper ore with a raw ore grade of 0.3% to more than 25% of the concentrate. The flotation machine is a key mineral separation equipment in the field of efficient recovery and beneficiation of complex polymetallic ores.
Core functions of flotation machines
- Precious metal ore: extraction of metals such as gold and silver.
- Non-ferrous metal beneficiation: sulfide ores and oxide ores such as copper, lead-zinc, molybdenum, and nickel.
- Ferrous metal separation: flotation and purification of iron ore, manganese ore, chromite, and ilmenite.
- Rare metal recovery: flotation and enrichment of spodumene, tantalum-niobium ore, lithium, and rare earth ore.
- Non-metallic ore processing: selection of fluorite, phosphate rock, graphite, etc.
Principle & Structure of flotation machine
Work principle
The flotation machine operates based on the principle of differences in the hydrophobicity of mineral surfaces: First, the crushed ore is mixed with water and flotation reagents to form a slurry, which is then fed into the flotation tank. Air is introduced through a stirring device, creating numerous tiny bubbles. The target minerals, modified by the reagents, exhibit hydrophobic surfaces and actively adhere to the bubble surface, rising to the surface to form a foam layer. Hydrophilic gangue minerals remain in the slurry. Finally, the foam layer enriched with the target minerals is scraped off by a scraper to obtain the concentrate, while the remaining slurry is discharged as tailings, completing the mineral separation process.
Structural Characteristics
- Pulp Tank: Contains the slurry, available in direct-flow and suction designs. Most are constructed from welded wear-resistant steel plates and equipped with a level control device to stably control the slurry level.
- Agitation System: Consists of a motor, transmission components, impeller, and stator, ensuring uniform slurry suspension.
- Aeration System: Introduces air into the slurry via a blower or compressor, providing controlled air bubbles.
- Scraper Device: A continuous scraper mechanism driven by a motor, periodically scraping away concentrate foam from the surface.
- Reagent Addition System: Precisely adds flotation reagents via metering pumps or pipelines, ensuring thorough mixing between reagents and slurry.
- Control System: Employs a PLC or intelligent control system to monitor flotation process parameters (such as pH, aeration rate, and agitation speed) in real time, achieving automated operation.
Types Of flotation machine
Flotation machines For Sale
There are three main types of JXSC flotation equipment, namely mechanical agitation flotation machines (SF, GF, BF, JJF type), inflatable agitation flotation machines (XCF type, KYF type), and inflatable flotation machines (XJB rod flotation machine).
During the flotation process, the reagents and the ore pulp to be selected are mixed and then put into the flotation equipment. After the stirring and aeration of the flotation machine, the bubbles and the ore particles are contacted, collided, and adhered to achieve the final mineralization. The target minerals float up with the bubbles to the surface of the ore pulp and become a foam layer, which forms the flotation concentrate; it is discharged from the flotation machine by scrapers or gravity. Non-target minerals are retained in the ore pulp area and discharged from the tank.
