A New Application For Flotation Of Oxidized Copper Ore

Sep 17, 2011· Then, the flotation must be capable to produce copper concentrates of low and high arsenic content. The second one must be treated by an alternative process. The treatment of copper ores with some degree of oxidation is other problem. In this case, the mine usually tries to send to the flotation process a material easy to treat.

Copper Ore Processing Methods

These oxidised copper minerals are found in weathered regions of most copper sulphide ore bodies The overlaying oxidic ore is usually stockpiled after it is removed from the sulphide lode and left unprocessed as the sulphide ore is simpler to recover by conventional flotation procedures and thus, more attractive to the plant operator.

A Review of the Flotation of Copper Minerals | O. Ndoro ...

Froth flotation is a process for selectively separating 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.

Flotation of mixed copper oxide and sulphide minerals with ...

Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture.

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY …

oxidized copper ore and different structures of copper ore have been carried out by many researchers using various flotation conditions. Oxidized copper ores are found in many places in the world. Formation of this type of ore occurs in the same locations as other copper ores…

A New Application For Flotation Of Oxidized Copper Ore

A method of refining sulfide is oxidized copper ores (RU # 2337160, publ. 27.10.2008), including collective flotation of sulphide and oxidized copper minerals from the ore, leaching of concentrate sulfuric acid solution involving ozone and/or hydrogen peroxide and ferric ions, dewatering and washing of the cake leaching and extraction of copper ...

Ore deposits formed by oxidation and supergene enrichment

The role of collectors in the flotation of partially oxidised copper ores . By Gregory Hangone. Get PDF (3 ) Abstract. The effects of xanthates, dithiophosphates, dithiocarbamates and mixtures of these collectors on the froth flotation performance of partially oxidised and oxidised copper sulphide ores were investigated in this study. ...

Perturbations from the recycled water chemical components ...

Oxidized ores in which malachite, azurite, and chrysocolla are the predominant copper minerals that do not respond either to gravity or simple flotation methods. Sulfide-filming of the carbonates followed by flotation of the filmed minerals, or direct leaching followed by precipitation of the copper from the solution may be employed for such ores.

Flotation Behavior of Iranian Oxidized Zinc Ore Using ...

In this study, we attempted flotation of oxidized copper ore. When this was unsuccessful, we used a sulfurization process developed in our previous studies. As a result of this process a new surface forms on the oxidized copper particles and flotation experiments were carried out using these samples (2-3).

Sulfide Ores - an overview | ScienceDirect Topics

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Ore Flotation Oxidized - australiandenbosch.nl

About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and ...

Flotation of a copper sulphide ore from Okiep using thiol ...

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
