The present invention provides a method to improve the cleaner froth flotation process for the selective separation of ore values including, for example, copper, zinc, molybdenum, iron, and mixtures thereof, in existing flotation plants comprising the step of adding one or more monocarboxylic acid polymers andor copolymers at the cleaner flotation step of the process.
Froth property measurements, together with on-stream analyzer assays, enable efficient and robust strategies to be put in place for advanced flotation process control, using a system such as Metso Outotec ACT. Provides consistent information for operators to control and optimize flotation processes
A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineralwater slurry.

Froth flotation is the most commonly used process to recover and upgrade the portion of the coal preparation plant feed that has a particle size smaller than 150 microns. Problems that occur when employing froth flotation in the coal industry include i coal surfaces that are weakly-to-moderately hydrophobic, and ii flotation systems that are overloaded and limited by insufficient retention time.
Mar 09, 1992 The improved flotation machine, cell and overflow froth launder design according to the invention includes a cylindrical tank and a unique hexagonal overflow launder configuration. The unique hexagonal overflow froth launder allows for a unique nesting of adjacent rows of
Dec 04, 2019 Accurate segmentation of flotation froth images is an important step in obtaining a bubble size distribution. In view of the problems of low segmentation accuracy of froth images and poor applicability of algorithms, an improved method for flotation froth image segmentation is proposed.
By implementing the right froth flotation program, Nalco Water was able to help improve overall recovery by 2 at the same dose as the incumbent product. The improved recovery ultimately helped to reduce the total cost of operations. Download the case study below to learn more.

Aug 31, 2020 Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp to the flotation froth, and the other from froth to the ...
