Flotation is a widely used method of concentrating ores, and it is believed to be the most commonly used ore dressing process. It is based on the fact that when air bubbles are introduced into a ground ore pulp, particles of some minerals will become attached to the bubbles, whereas other minerals will not become so attached and remain in the pulp.

flotation. 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.

Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in Colloid and Interface Science, 2005.
compressed air, separates the ore into fractions. Depending upon the chemicals used, some minerals float to the surface and are removed in a foam of air bubbles, while others sink and are reprocessed. Pine oils, cresylic acid, and long-chain alcohols are used for the flotation of copper ores. The flotation

Today column flotation has become . an accepted means of froth flotation for a fairly broad range of applications, in particular the cleaning of sulfides (copper, zinc, lead and molybdenite) and the flotation of iron ore, phosphate and coal. Flotation columns differ dramatically from mechanical flotation machines in . several ways:
Bench scale flotation is used to determine how the reagents affect flotation performance when the scale of flotation and slurry density is increased. As such this paper is synopsis of a more in depth thesis research effort [9]. Methods and Materials The ore samples used in this flotation research were obtained from Mountain Pass Mine in California.
Provided is a method involving flotation of a feed of platinum group metal ore material to prepare a platinum group metal concentrate during mineral processing operations. Prior to and/or during the flotation, a lead-containing activator reagent and a xanthate collector reagent are added to the slurry and during the flotation, an oxygen-deficient flotation gas, such as nitrogen gas, is used.
May 16, 2016· A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel ...
Froth flotation is mainly operated under two common techniques : 1. Direct floatation technique – In this method, the mineral sticks to the air bubble and the remaining gangue settles down at the bottom. 2. Reverse floatation technique – In this method, the gangue sticks to the air bubble and ore particles settle down in the bottom.

been from ore first discovered by the Remans.3 At Rio Tinto, the Remans mined the upper, ox-idized, part of the ore and collected the copper-Iaden solutions produced by water slowly seep-ing down through the suIfide ore bodies. When the Moors conquered this part of Spain during the Middle Ages, the oxide ores had largely been exhausted.

In terms of flotation, the development of more selective collectors and reagents is critical to its success in treating these low grade, difficult to process ores. In a froth flotation process, the ore is subject to comminution, such as by crushing and wet grinding, to reduce particle size of the mineral ore.
