DR flotation system and column flotation system

DR Flotation Cell System

The Reactor Cell System Flotation Machine is the preferred choice for many mineral flotation applications. The DR design may be specified for certain applications, particularly where de-slimed coarse particles have to be handled such as in glass and potash processing.

Features of the DR design are as follows:
• Open flow tank with intermediate and discharge boxes
• Near bottom located impeller/ diffuser
• Separate source of low pressure air
• Level control by weir or dart valves (automatic as option)
• Recirculation well
• Reversible impeller direction of rotation
Column Flotation Cell System
Flotation column work on the same basic principle as mechanical machines such as KYF flotation machine. However, in column flotation there is no mechanical mechanism. Separation takes place in a vessel of high aspect ratio and air is introduced into the slurry through spargers.
In certain cases such as cleaning duties or handling of very fine particles column
flotation will offer the following advantages:
• Improved metallurgical performance
• Low energy consumption
• Less floor area
• Less maintenance
• Improved control
Schematic of Flotation Column
The CISA Sparger consists of inline Static Mixers and a Recycle Slurry Pump. Tailings Slurry is pumped from the base of the column through the static mixers where air and
slurry are mixed together under high shear conditions to create the bubble dispersion. As the air/slurry mixture passes through the stationary blades located inside the mixer the air is sheared into very small bubbles by the intense agitation. The bubble suspension is introduced near the column base. Slurry Level Control is achieved by using Dp or ultrasonic sensors to
automatically adjust the Tailings Control Valve. Wash Water addition improves grade by removing mechanically entrained particles.
Applications
Applications for Flotation Columns include:
• Copper
• Graphite
• Lead
• Phosphate
• Zinc
• Coal
• Iron
• Fluorspar
sinonine can also provide sand washing plant EPC.

Mineral froth flotation

图片
Sinonine deeply know that in a beaker of water, if air is introduced from the bottom, air bubbles are produced  and rise to the surface of the water as the density of an air bubble is much less than that of water (Figure.1 A). Similarly air bubbles also rise if air is introduced in a pulp containing mineral particles. If a mineral particle of high density adheres to the air bubble, the air bubble along with the mineral particle rises to the surface because the apparent density of the air bubble and the adhered mineral particle is less than that of water. If many mineral particles are adhered to the air bubble, still the air bubble rises to the surface as the apparent density of the air bubble and adhered mineral particles is less than that of water due to the relatively large volume of the air bubble Figure 1 B). This concept is the basis for froth flotation operation. To use this concept or phenomenon, the following are required: 1 Method to make the mineral particles adhere to

How to extract silica sand from kaolin tailings?

图片
This paper describes in detail the method of extracting silica sand from sandy kaolin tailings, which can make full use of tailings and improve the application value of kaolin tailings. Its silica sand concentrate fully meets the requirements of glass quartz sand index. Kaolin and its tailings Kaolin is an important non-metallic mineral material. It is not only a necessary raw material for building materials, light industry and other traditional industries, but also a basic material for the development of modern industry. Kaolin mineral resources are continuously exploited and utilized, and a large number of tailings will be produced in the process of mining and processing of kaolin, and the number of tailings will increase year by year. The continuous accumulation of tailings occupies a large amount of land, which affects the ecological environment and also causes the waste of mineral resources. The treatment methods of Kaolin Tailings mainly include: building t

The motion of the charge in a ball mill

图片
The distinctive feature of ball mills is the use of loose crushing bodies, which are large, hard, and heavy in relation to the ore particles, but small in relation to the volume of the mill, and which occupy slightly less than half the volume of the mill. Due to the rotation and friction of the mill shell,the grinding medium is lifted along the rising side of the mill until a position of dynamic equilibrium is reached, when the bodies cascade and cataract down the free surface of the other bodies, about a dead zone where little movement occurs, down to the toe of the mill charge (Figure 1). Figure1. Motion of charge in a ball mill The speed at which a mill is run is important, since it governs the nature of the product and the amount of wear on the shell liners. For instance, a practical knowledge of the trajectories followed by the steel balls in a mill determines the speed at which it must be run in order that the descending balls shall fall on to the toe of the charge, an
