Introduction of Flotation machine

Flotation machine is for processing minerals by means of froth flotation, which is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.

Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also upgraded by flotation technology.

The application of Flotation machine

Flotation is a selective process and can be used to achieve specific separations from complex ores such as lead-zinc, copper-zinc, etc. Initially developed to treat the sulphides of copper, lead, and zinc, the field of flotation has now expended to include platinum, nickel, and gold-hosting sulphides, and oxides, such as hematite and cassiterite, oxidised minerals, such as malachite and cerussite, and non-metallic ores, such as fluorite, phosphates, and fine coal.

Types of flotation machine

Industrial flotation machines can be divided into 5 classes, mechanical agitation flotation machine, pneumatic flotation machines, flotation column, airlift flotation machine, froth separation flotation machines.

At present, the mechanical flotation machine is the most commonly used in industry, followed by the column flotation which has recently set off hot spot, the pneumatic type and froth separation are not common.

The structure of flotation machine

Flotation machine is composed with slurry tank, agitator device, mineralized froth discharging system, electromotor, etc.

1. Slurry tank: mainly consist of a slurry inlet, slurry tank and a gate device for controlling the slurry volume, welded with steel plate.

2. Agitator: slurry tank have a series of the mechanically driven impeller that disperses the air into the agitated pulp.

3. Mineralized forth discharging: the useful minerals are enriched in the foam, scraped out, dehydrated, and dried into concentrate products.

How to choose a suitable flotation machine?

1. The throughput capabilities of various cell designs will vary with the ore property (beneficiability, size, density, grade, pulp, PH, etc.). In the case of ore easy separated, and a small amount of air inflation required, may choose a mechanical flotation machine; if the minerals with coarse size, proper to choose the KYF, BS-F, ore CLF type; what's more, when in case of ore easy separated, fine particles, high grade, low PH, flotation column is the best, especially in the concentrating process.

2. There is a difference between the process of concentrating, rough selecting. Thin froth layer is better for separate mineral particles, thus may not choose a large air inflation flotation machine.
