— The Lead Zinc Copper Flotation and Separation Circuit. Every effort is made to recover the minerals as soon as free. Over-grinding causes slime losses which are both unnecessary and costly. The flowsheet is designed for a compact mill of a size that provides economical treatment at this tonnage.

Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.

Froth flotation is a physicochemical separation process in which a mixture of fine mineral particles is mixed with water in a large tank (cell), and a swarm of small air bubbles (several millimeters in size), generated at the bottom of the tank, is allowed to pass continuously through the slurry.

 — A total recovery of more than 97% of the gold and silver is made by flotation, while the combined flotation-cyanidation process gives an overall extraction of 95%.

 — For silver-bearing lead–zinc ores, preferential flotation process is used for high-grade ores that are easy to dress, with a simple flotation circuit. Zinc-sulfur bulk flotation process is applicable to low-grade ores with lower beneficiation costs through discarding tailings in advance.

This paper studies and determines the dispersion properties (Jg, Eg and Db), kinetics parameters and hydrodynamics of the process and its effect on the recovery of silver contained in spent diluted fixers by techniques of ion flotation in columns.

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 mineral/water slurry.

FLOTATION Flotation is the most widely used mineral separation method. It is the preferred method of mineral recovery for many of the most important minerals that are recovered and large tonnages of ore are processed by flotation annually. The underlying principles of the flotation process are well established but it has proved to be

 — The focus of this research was to investigate the flotation properties of silver-bearing minerals. Specimen-grade, silver-bearing tetrahedrite and a tabling concentrate from an Alaskan lead-zinc mill were chosen as typical sources of silver.

 — For the separation of iron ores, the froth flotation process is most significant method which yields high-quality iron from low-grade, finely disseminated iron ores. Higher flotation rates, use of simpler reagent systems, and low operation temperature are the characteristics of cationic reverse flotation process.
