Flotation:
Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles. The driving force for this attachment is the change in the surface free energy when the attachment occurs. These bubbles rise through the slurry and are collected from the surface. To enable these particles to attach, careful consideration of the chemistry of the pulp needs to be made. These considerations include the pH, Eh and the presence of flotation reagents. The pH is important as it changes the charge of the particles surface and the Eh effects the chemisorption of collectors on the surface of the particles.
The addition of flotation reagents also effects the operation of these processes. The most important chemical that is added is the collector, This chemical binds to the surface of the particles as it is a surfactant. The main considerations in this chemical is the nature of the head group and the size of the hydrocarbon chain. The hydrocarbon tail needs to be short to maximize the selectivity of the desired mineral and the headgroup dictates which minerals it attaches to.
The frothers are another important chemical addition to the pulp at it enables stable bubbles to be formed. This is important as if the bubble coalesce, minerals fall off their surface. The bubbles however should not be too stable as this prevents easy transportation and dewatering of the concentrate formed. The mechanism of these frothers is not completely known and further research into their mechanisms is being performed.
Depressants and activators are used to selectively separate one mineral from another. Depressants inhibit the flotation of one mineral or minerals while activators enable the flotation of others.
There are a number of cells able to be used for the flotation of minerals. these include flotation columns and mechanical flotation cells. The flotation columns are used for finer minerals and they typically have a higher grade and lower recovery of minerals than mechanical flotation cells. The cells in use at the moment can exceed 300 m3. This is done as they are cheaper per unit volume than smaller cells, but they are not able to be controlled as easily as smaller cells.

Star Trace STDP series hydraulic type dredge pump is our new product with our own research and development and production, with on-site commissioning, construction experience, its own production of the first domestic product manufacturers in india . It is mainly used as an excavator attachments, under inconvenient circumstances of more water, mud, mortar, more dilute unfavorable mining and transport vehicle , using this kind of dredge pumps for Extraction operation, it greatly enhance the work efficiency, it is widely used in inland channel dredging project, the port of sediment management, tailing pumping , mineral processing, municipal sewer discharge sludge and etc.

Working principleSTDP hydraulic dredge pump is provided power by the hydraulic system, the motor of the actuator, it is new type of submersible dredge pump by converting the hydraulic energy into mechanical energy . When Working through the pump impeller rotating stirring, transfer energy to the slurry medium, to produce a certain flow velocity, driven solids flow to achieve sand slurry transportation.
The hydraulic motor is Selection of domestic high-speed hydraulic motors series gear motors or quantitative piston motors, with feature of advanced and reasonable structure, good performance, high efficiency and stable working. According to the customer situation, we choose different displacement.
Key FeatureIn the bottom of the pump with a agitation device, and while both sides and multilateral sides we can be equip with a separate agitators , which can prevent a bulk solid clogging the pump, and the solid thoroughly mixed with the liquid, which allows easier handling.The pump can handle a maximum particle size of 50mm solid material, the solid-liquid extraction concentration up to over 70%; Note: Due to the different site condition, pump capacity may also be changed with affect of medium conditions, site operations, transport distance and other factors.The dredge pump unit is mainly mounted on the excavator, power is provided by hydraulic excavators, which can achieve free transitions, and the power source is a diesel engine that can solve the power problem of inconvenience during the construction in remote areas.The whole pump including: the pump casing, impeller, guard plate, agitator impeller are made of high-chromium alloy. Other materials can be customized.Using a unique sealing device for the frequent replacement of the mechanical seal will improve work efficiency.
Main Applications Harbors, rivers, lakes and other dredging, removing sediment and etc.;Extraction silt, gravel, etc., harbor reclamation project;Iron ore, tailings, slag processing plant and other mining, pulp and discharge all of the solution containing the solid ;In metallurgy, steel and other industries to pumping high concentrations of tailings, waste and high-temperature iron slag, iron and etc;Pumping sand, gold ore and so on.
