Apr 04, 2016· Froth flotation is a separation process in which air bubbles are introduced in a water tank to separate the valuable commodities from the valueless material. Based on their relative affinity to water the valuable particles attach to the bubble surface and are carried to the top of the flotation tank to form the froth layer.
The present invention provides a froth flotation process for the separation of paper and wood fibers from printed and copying inks and other contaminants during the recycling of paper. A liquid solution containing a frothing agent is applied from the top of a froth flotation device, preferably in the form of a spray, to the upper surface or portion of an aqueous pulp slurry present in the ...
Froth flotation is a separation process which plays a major role in the mining industry. It is essentially employed to recover a vast array of different valuable commodities such as …
• A Froth Flotation operation can consume enormous volumes of fresh water, 10 Freeport McMoran plants alone used 185 billion gallons of water in 2013. • These operations often occur in arid areas where water can be in short supply, thus using such quantities can mean that living things may suffer.
