the phenomenon of floating (remaining on the surface of a liquid without sinking)
the process of separating minerals by agitating a mixture with water and detergents etc; selected substances being carried to the surface in air bubbles
the process of removing finely divided particles from a liquid suspension by agitating the liquid with gas bubbles thus increasing the buoyancy of the particles, and concentrating them at the surface of the liquid medium
The process in which ore is separated from gangue Ore is agitated in a bath of special liquid so the metallic ore fraction either rises or sinks to the bottom and the gangue does the opposite
Float in tanks filled with sterile salt water regulated so that its temperature is precisely the same as your body temperature for a sense of buoyancy and weightlessness You float in complete sensory isolation so that no nerve impulses move from the skin to the brain for a unique feeling of relaxation Can be used in complete silence, music or guided imagery More about this subject
A therapy that uses tanks filled with sterile salt water with the temperature regulated to be the same as your body, provides a sense of buoyancy and weightlessness Either in complete isolation or with music and images, this treatment serves to induce complete relaxation
Issue and placement of securities on the capital market by public sale Usually by the intermediary of a bank (bank of issue) or a consortium of banks The issue price of shares should not fall below the face value The issued document is also referred to as a floatation
A solids-liquid or liquid-liquid separation procedure, which is applied to particles of which the density is lower than that of the liquid they are in there are three types: natural, aided and induces flotation Flow The discharge rate of a resource, expressed in volume during a certain period of time
is time spent out of time lying face up in a 10 inch deep pool of skin-temperature, salt-saturated water, effectively simulating weightlessness The tank environment is silent and typically totally dark, reducing sensory input to an absolute minimum In this non-intrusive environment, the body disappears, and the mind slows and stops, expanding into essential consciousness Flotation allows deep levels of relaxation, producing emotional tranquility, mental clarity and physical rejuvenation
Method by which hydrophobic (water-repelling) particles of an ore are separated from hydrophilic (water-attracting) particles of a metallurgical pretreatment process
A technique used to extract objects from soil by using churning water or other liquids to carry away the soil, leaving larger objects to be caught by a screen
A technique used to separate solid materials by using a solvent such as water and floating the desired substance off the surface In fruit flotation, silicates are added to water to modify the density of the water to allow the fruit to float, and to aid in the cleaning of their surfaces In ore processing, separates the desired material from the gangue or undesired material In deinking, separates the ink from the pulp
A technique for recovering small objects – charcoal, carbonised seed, small bones – from soil by washing in tank(s) of running water and removing the resultant scum and sediments with a sieve
A flotation compartment helps something to float because it is filled with air or gas. or froth flotation Most widely used process for extracting many minerals from their ores. The method separates and concentrates ores by altering their surfaces so that they are either repelled or attracted by water. Unwetted particles, which adhere to air that is bubbled through the water, will float in the froth, while wetted particles will sink. The process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants. With its use to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores, many complex ore mixtures formerly of little value have become major sources of certain metals
The process of mixing ground ore with water chemical reagents and air to separate mineral particles from waste rock The mineral particles stick to the air bubbles and float to the surface The froth is collected and dewatered to produce concentrate for smelting or further processing
a milling process by which some mineral particles are induced to become attached to bubbles of froth and float, and others to sink, so that the valuable minerals are concentrated and separated from the gangue
The first occasion on which a public companys shares are offered widely to investors on the market Flotations are often referred to as new issues although it is possible for companies already in the stockmarket to issue new shares
A form of concentration of certain minerals from gangue based on their different surface reaction to chemical flocculants A reagent (chemical flocculants) is used to adhere to the target mineral, which then rises to the top of the flotation cell with injected air, where it can be collected
a process by which some mineral particles are induced, by the introduction of specific reagents, to become attached to bubbles and float while other particles sink; the valuable minerals are concentrated and separated from the gaunge
A process by which some mineral particles are induced to become attached to bubbles and float, and other particles to sink, so that the valuable minerals are concentrated and separated from the worthless gangue
Is experienced in a flotation tank, which is a specially designed chamber containing sufficient salt-saturated water to enable one to float In this sate of suspension one can free the mind from outside stimuli by creating a relaxed and unencumbered state The participant lies in the super-saturated-salty water, which has tremendous buoyancy, and by absorbing the force of gravity; one floats effortlessly, thus allowing the mind and body to release tension Floating weightlessly in a sound and lightproof environment can be a unique and liberating experience relieving stress and enhancing the ability to concentrate
