Froth flotation

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December , 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.Flotation properties of individual minerals described here are based on the study of many natural ores in the laboratory as well as pilot plants. Chalcopyrite, CuFeS 2 (Cu, 34.56%; Fe, 30.52%; hardness, 3 4 and specific gravity, 4.2). Chalcopyrite together with chalcosine is one of the most important minerals for the production of copper.Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

need for an improved method of recovering the oxidized copper minerals associated with the sulphide copper ores. The above factors led to the selection of this subject as a research problem. SCOPE OF '.;oRK DONE. Effective flotation of an are 1s the result of several factors: selection of suitable reagents; the proper combination of reagents, pro­A new reagent system, developed by Versitech, Inc., with assistance from DOE's Inventions and Innovation Program, recovers copper minerals at a much lower pH than conventional reagents and avoids floating pyrite. The process reduces or even eliminates both the lime used in copper flotation and the accompanying carbon dioxide.Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.

Sulphide ores are the major sources of base metals like Copper, Lead, Zinc, Nickel and Cobalt. Beneficiation of. these base metal sulphide minerals is predominantl y through the froth flotation ...1.1.4 Flotation Reagents The chemistry of flotation consists of collectors, frothers, and conditioning reagents (modifiers). Coal flotation is primarily concerned with collectors and frothers. Collectors are the heart of the flotation process since they are the reagents that produce the …reagents on the design and operation of flotation plants (Section 4A); and on the use of statistical methods for designing laboratory and plant experiments and the evaluation of the results obtained there.

Flotation Copper Sulphate Pentahydrate Activator for sphalerite (ZnS), pyrite (FeS2) in base metal ores Lead Nitrate Activator for stibnite (Sb2S3) in antimony oresEffective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.AERO® is proposed as the copper mineral collector in the flotation process. AERO® coats the mineral surface, rendering the copper mineral hydrophobic. The coated minerals attach to air bubbles blown into the flotation tank, allowing the copper-molybdenum concentrate to float to the top of the tank where it is skimmed off.

 · Gold flotation reagents can be divided into 5 types: collectors, ing agents, inhibitors, activators, and pH regulators. Flotation reagent is one of the key factors affecting the flotation of gold ore. It can adjust the surface properties of gold ore during the flotation process, and improve the flotation speed and selectivity. This article will briefly introduce the working principles ...hydroxamates/ chelating reagents as collectors to improve the grade/recovery. The study also highlighted the importance of understanding the ore mineralogy in the development of a flotation procedure since all copper minerals respond differently to different flotation ... Figure 2.7: Effect of levels of different sulphidisers on copper ...Oxide copper ores in subdivided form may be concentrated in a flotation separation process by slurrying said ores in an aqueous solution of a flotation reagent followed by generating gas bubbles in the slurry to float the oxide copper and recovering the concentrated oxide copper from the surface of the slurry, wherein the flotation reagent is a quaternary hydrocarbyl ammonium or phosphonium.
