This is still my dream. Now after almost 40 years with Outokumpu and Outotec I retired at the end of June 2014 and I can say that it has been fun and I got to know, and had the pleasure of working with, a lot of excellent people, many of whom became my friends over the many years. Thank you all. Let's keep in touch. [email protected]

TECHNICAL NOTES 9 FLOTATION - mineraltech.com

froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.


"CHARACTERIZATION AND DESULPHURIZATION OF REACTIVE …

A site-specific study is carried out to assess the suitability of froth flotation for desulphurization of reactive mine tailings with an Outokumpu flotation unit, type OK0.05 at the Musselwhite Gold Mine, Northern Ontario, Canada, to prevent acid mine drainage (AMD). Based on the data presented in this study, the maximum recovery of total sulphur was achieved when the operational parameters ...


"Study on the surface chemistry behavior of pyrochlore ...

Separation of pyrochlore from its associated minerals is typically accomplished by froth flotation. The surface chemistry of pyrochlore is similar to many of its associated non-value minerals. Therefore, understanding the surface chemical properties of the pyrochlore for selective pyrochlore flotation will potentially aid in the design of flotation strategies for optimized recovery.

Feb 01, 1999· This paper is a summary of the author's industrial experiences on the selection and optimization of flotation reagent schemes for the recovery of gold species. The trends given are a composite of data and experiences gained on 24 different gold ores from around the globe. The primary emphasis is on the benefits of matching the associated gold mineralogy to a reagent scheme most …


Evaluation of Environmentally Friendly Collectors for ...

Jan 01, 2011· Collectors play a vital role in froth flotation. There are reagents possessing both a polar group that binds them to the mineral surface and a nonpolar group that is oriented away from the surface to attach air bubbles. The introduction of xanthate as a sulfide collector in 1925 was a remarkable development in froth flotation (Keller, 1925).

The use of alkaline pressure oxidation to pretreat refractory gold ore often results in insufficient gold recovery (<60%) in downstream thiosulfate leaching. To improve gold recovery, flotation was considered for the separation of carbonaceous matter (C-matter). In this study, the effect of MIBC on C-matter flotation was investigated to understand the role of the frother in bubble and froth ...


Frothers | Quadra

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.


The development of statistical ToF‐SIMS applied to ...

Jun 06, 2017· The role of surface chemistry in recovery of minerals is central to several processes such as froth flotation, leaching, and electrostatic separation. In separation of base metals (eg, Cu, Pb, Zn, and Ni) by froth flotation of their minerals, usually sulphides, the attachment of these mineral particles, after hydrophobic collector addition, to ...

Handbook of Flotation Reagents | ScienceDirect

1 - Classification of Flotation Reagents. Modern classification of flotation reagents is based on the function of a particular reagent. On this basis, reagents are divided into collectors, frothers, regulators, and depressants. Collectors are a fairly large group of organic chemical compounds, which differ in chemical composition and function.


Packed column flotation for fluorspar beneficiation ...

Nov 01, 1992· A comprehensive flotation study has been conducted on a Chinese fluorspar ore using the packed flotation column developed at Michigan Technological University (MTU). The results are compared with those for a conventional mechanical-flotation method on the same feedstocks. Key factors controlling flotation performance of both methods are evaluated based upon a simple statistic …
