7 Factors Affecting Froth Flotation Process - JXSC Machine

Froth flotation, separation of ... Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove ...

Froth Flotation Method - 1699 Words | Internet Public Library

Frothing, also known as froth flotation, is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method whereby minerals can be "skimmed" from the surface of "slurry" that is "foamed" with the assistance of specific chemicals, water and air bubbles.

Froth Flotation and Gold Extraction - Manhattan Gold & Silver

Froth flotation method is an efficient method for reduction in sulfur and ash content. The underlying principle of the said process is formation of the froth upon contact of frother with coal particles. Pine oil dosage being the control parameter, the analysis showed that maximum sulfur reduction of 33 % was obtained for 30 minutes flotation ...

Answer: a. Sulphide ore. Explanation: The process of separation of hydrophobic and hydrophilic material from ore is called froth flotation.. This process is primarily used for purification of sulphide ores.. In this process, the difference in wetting of minerals and gangue is taken as an advantage .. Minerals are wetted by oil while gangue is wetted by water.Thus a mixture of water, crushed ...
