    Jun 16, 2013 Froth floatation 1. Froth Floatation Presented By: Gulfam Hussain 2. Introduction Floatation is an extractive process where various minerals can be selectively extracted. Flotation is a selective process and can be used to achieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn- Cu, floatation allows separate extraction of Pb, Cu

    Froth Flotation Process Ppt 2017-3-23The typical range for a froth depth is 600 mm from the top of the flotation cell, the launder, down to the slurry interface. Here we are actually trying to measure the depth of a froth, or foam layer. Since the level we are interested in is covered in froth, measuring it is a lot more challenging

    1 Froth Flotation – Fundamental Principles

    1 Froth Flotation – Fundamental Principles 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. The particles with attached air bubbles are then carried to the surface and

    The conventional froth flotation method is applied to the coal for three aims: (1) to obtain a product with low sulfur and ash content by recovery of the coal in slime, (2) to diminish pollution of the environment by cleaning the process water, which is called black water and is removed from the coal preparations plant and (3) to produce coking
