The Disc Filters belong to the side feed group and have been around for many years. They are generally used in heavy duty applications such as the dewatering of iron ore taconite, hematite, coal, aluminum hydrate, copper concentrate, pyrite flotation concentrates and other beneficiation processes. The high time for Disc Filters was in the 60''s when the metallurgical industries were booming and

Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture. Filters can be categorised by the main method of capture, exclusion of particles at the surface of the filter media straining, or deposition within the media indepth

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

· Multilayer structured filters with varying pore sizes stacked on top of another offer a simple way of sequentially separating cells or particles (Saefkow, 1995; Rijn, 1998). In a recent study by Griffiths et al. (Griffiths et al., 2016 ), filtration was modeled on a multilayered membrane structure with each layer having varying pore sizes stacked on one another.

The magnetic collection of fine particles requires a highintensity, highgradient magnetic field. An electromagnetic matrixtype separator, referred to as a magnet filter, has proven to be the most effective method of separation. This type of separator utilizes a highintensity electromagnet and a fluxconverging matrix. The matrix amplifies the magnetic field and provides highgradient

The objective is to extract only the most magnetically susceptible particles; Discs 2 and 3 – The second and third discs are set at lower gaps. This increases the magnetic force at each disc and enables the separation of different grades of magnetic material. The magnetic intensity can be further adjusted by varying the current of each coil. This allows each Magnetic Disc Separator to be

Density separation is achieved with basically two components, mechanical vibration and air fluidization. The Gravity Separator makes a highly sensitive dry separation on the basis of one of three particle characteristics: density, size or shape. When size and shape are controlled within certain limits, the gravity separator is unmatched in its ability to separate a complex mixture by density

The basic design characteristics of the rotating disc filter, like filtering under vacuum, washing the cake under vacuum and removing the cake by blowing the cake off the filter are the same as in the drum filter. Instead of one drum, a number of discs are placed in parallel. The lower end of each disc is

Hence Disc Stack centrifuges are more suitable for processes which require high separation efficiency or the separation of micro particles, or liquid phases having a very small difference in density. The Disc Stack centrifuge has a wide range of applications including but not restricted to food and beverage, animal and vegetable fats and oils, chemistry, pharmacy, biotechnology, mineral oil

In isopycnic separation, also called buoyant or equilibrium separation, particles are separated solely on the basis of their density. Particle size only affects the rate at which particles move until their density is the same as the surrounding gradient medium. The density of the gradient medium must be greater than the density of the particles to be separated. By this method, the particles

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the

separation of minerals at coarser sizes as soon as liberation is achieved can also have signifi cant advantages for later treatment stages due to decreased surface area, more efficient dewatering, and the absence of adhering chemicals which could interfere with further processing.

Filter aids such as diatomaceous earths and expanded perlite are so irregular that they form beds whose solidosities range from to, even though the primary particle sizes may be below 10 μm. Stresses developed in the matrix of large particles during separation processes do not generally reach sufficient magnitude to disturb the structure.

The purpose of screening is to separate from a granular substance particles that are smaller than the screen opening from those that are larger. This is not as simple as it sounds, and the difficulties compound as the opening becomes smaller. For example, if a sample of a crushed mineral ore containing 50% by weight of particles smaller than 1/8" is dropped on a static test sieve, most of

process U Q () for a given particle size there will be a certain flow rate (Q) at which all particles of this size are removed. If this flow rate is exceeded then particles of this size start to appear in the effluent. Thus, the process variables (size and flow rate) defines the sigma value.
