New directions in flotation machine design ScienceDirect

An important feature of the test circuit is the ability to recycle a fraction of the tails for further treatment The volumetric recycle ratio S is defined as the ratio Q RT Q NF where Q RT Q NF are the volumetric flow rates of recycled tails and new feed respectively m 3 h Thus the number of times N that a particle passes through the Cell is on average N 1 S

Froth Flotation Circuit Design And Basic Testwork

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


Column flotation cells have become the most popular separation device designed for industrial applications requiring the concentration of wanted or unwanted mineral from the rest material in a pulp To achieve separation an air sparging device is required to produce bubbles in the flotation cell In column flotation operations sparging

Flotation Process Audit and Bottleneck Identification

The objective of hot flotation tests is to transfer process slurry properties to a laboratory scale flotation cell by collecting a test feed sample directly from a process stream The main outcomes of hot flotation tests are the recoveries grades and kinetics of the main minerals from a certain flotation stage
