Flotation ore dressing Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Pilot Mill Flotation of Serpentinized Platinum Palladium

The Bureau has conducted flotation studies on the anorthositic ore from the complex but not on serpentinized ores (3-a 4). This report presents the results of pilot mill study using xanthate-normal dodecy1 mercaptan suites in the flotation of serpentinized ore from Anaconda's Min neapolis Adit on the Howland Reef. ACKNOWLEDGMENT


responsible for the observed complex flotation behavior. INTRODUCTION Currently beneficiation of hematite ores is conducted using either direct flotation (hematite flotation) or indirect flotation (quartz flotation) tech-niques depending upon the nature of the available ore bodies. In direct flota-

Investigations into the Recovery of Platinum Group

In the flotation of platinum group minerals (PGMs) it has generally been assumed that they will behave similarly to base metal sulfides and thus sulfide reagent regimes are generally used in such flotation plants. However the tellurides and arsenides of platinum and palladium contribute about 50% of the PGMs present in the Platreef ore, located in the northern limb of the Bushveld Complex of ...

Oxidation of Complex Ni Cu Sulphide Ores and its

A complex ore containing galena ... The detrimental effects of slimes on the flotation of rutile from eclogite ore have been studied in this work in order to improve the separation efficiency of ...

Interactive effect of minerals on complex ore flotation A

Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation of iron ores, magnesite ores, and scheelite ores ...

Complex sulphide ore flotation Effect of depressants

Dec 10, 2016 Bench-scale flotation tests. The procedure followed for flotation tests is a standard optimised method at Boliden laboratory in the treatment of complex sulphide ores. For each flotation test, 1 kg of ore of − 3 mm is wet ground with 0.6 l of water for 20 min.

Interactive effect of minerals in the flotation of complex

the flotation of complex iron ores, magnesite ores and tungsten ores in recent years were summarized. It mainly includes the regularity and mechanism of the interactive effect, and methods of...

Flotation Behavior of Complex Sulfide Ores in the Presence

Jan 01, 2017 Flotation process is widely used to separate these minerals in sulfide ores [1]. A wide range of chemical reagents are used in the flotation process to separate the different minerals. Most of these reagents such as cyanides are toxic in nature and …
