US8657118B2 Collector for the flotation of carbonates

The invention relates to a collector for the separation by flotation of carbonates contained in non-sulfurous minerals, particularly phosphoric rock, comprising at least one phosphoric ester of formula (I) wherein, R 1 represents H, CH 3 or C 2 H 5 , R 2 represents a linear or branched alkyl or alkenyl group containing between 4 and 10 carbon atoms, R 3 represents H or a suitable cation ...

Beneficiation of Bastnaesite Ore with New Flotation

collector. A rougher flotation experiment produced a rare earth oxide grade and recovery of 41% and 78%, respectively with a 91.5% rejection of calcite. Collector 8 and 14 also showed promising results to replace fatty acid. As such, this patent pending technology can serve to provide a pathway for efficient domestic REE production.

Oxide Flotation Collector Collector for Copper Oxide Ore

Jul 25, 2013 In this flotation tests and evaluation for the best collector for copper oxide “ore” 911Metallurgy continues with material that’s 60% Oxide copper.. Sample C: 1.7% Copper about 60% Oxide Cu . Rougher Tests:. Both reagents appear to behave similarly as the “blue dots” are seemingly a continuation of the trend started by “red dots”.

Flotation Reagent an overview ScienceDirect Topics

These flotation reagents preferentially adsorb at the solid–liquid interface, making the surface of wanted minerals water repellent and facilitating bubble-particle attachment. They are classified based on composition and whether they exist as cations, anions or molecular species in water. Therefore, collector molecules may be ionizing compounds, which dissociate into ions in water, or non ...

Diethylenetriamine DETA Dow Inc.

A collector that enhances flotation separation, for use in the collection of iron and other metals, and in certain types of ores including gold and pyrite. Also used as a concrete anti-shrinking agent which reduces surface tension and minimizes shrinkage/cracking as water evaporates from concrete. It is also a building block for asphalt modification additives and in the manufacture of ...

pH Modifiers ArrMaz

ArrMaz’s line of tailor-made pH modifiers increases the efficiency of the flotation process by facilitating optimum zeta potential, and creating ideal conditions for collector function and mineral separation. They sequester soluble divalent ions which could potentially increase flotation collector usage and decrease collector efficiency, and ...

Flotation Reagents amp Collectors ArrMaz

Flotation Reagents & Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to …

Flotation Collectors Mineral Processing amp Metallurgy

Aug 10, 2015 What is a Flotation Collector. For industrial sulfide mineral flotation, the xanthates and dithiophosphates are the major classes of Flotation Collectors compounds used, where M+ is either Na+ or K+, and R is a relatively short hydrocarbon chain typically containing two to five carbon atoms. The solubility, pH application range, physical state ...

Chapter 7 Adsorption Mechanism of Flotation Collectors

7.1 INTRODUCTION. The adsorption mechanism of flotation collectors on mineral surfaces is a highly complex phenomenon. Even with today's scientific approach to mineral processing, there remain unresolved aspects with respect to collector adsorption. This can be best illustrated through some passages from contributing investigators.

Collection and Selectivity Contrast of Propyl Gallate and

Feb 24, 2021 Using an effective collector is often the key to improving the flotation recovery of valuable mineral concentrates. China’s diaspore-type bauxite is a refractory ore, since silicate minerals, such as kaolinite, are often closely embedded with diaspore. Propyl gallate (PG) is an effective and novel collector of diaspore.
