INTRODUCTION Uranium in nature occurs as oxides and oxysalts defining their higher chemical affinity for oxygen than for sulphur. Apart
Uraninite and masuyite are the major uranium minerals, essentially fine grained, in the ores studied. Over 40% of the uranium is distributed in the -8µm fractions compared with copper, which is concentrated mainly in the +8-20µm range. Uranium is concentrated mainly in the copper ore zones, with only marginal levels in the gold-only ores. Poor liberation (due to association with copper

Jul 01, 2015· A great amount of work has been published and further research is continuously being undertaken to improve recovery and grade of gold in copper flotation circuits (Agorhom, 2014, Allan and Woodcock, 2001).Furthermore, naturally occurring elements such as fluorine, uranium and arsenic often occur in copper ores as minor or accessory elements.
uranium ore sample from Domiasiat, Meghalaya. A combination of potassium amyl xanthate, cupferron and light diesel oil was used as collector for flotation of uranium bearing minerals in the sample. The effects of various process parameters were studied. Under the optimum conditions the flotation concentrate weighed about 35 % with over 90 %

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.

The flolation behaviour of some Australian uranium ores was investigated. Although uraninite and pitchblend float readily with fatty acids, selective concentration to produce an economically discardable tailing has not yet been achieved. This is attributed to the presence in the ores of a quantity of uranium mineral in finely dispersed form which is very difficult.

The mine has processed more than 2 billion tonnes of ore through leaching and flotation since opening more than 25 years ago. Today it accounts for almost 5 percent of worldwide copper output

Supergene copper ores rich in sulfides may be concentrated using froth flotation. Types of copper ore: More information. An additional point to note is that chalcopyrite, silver and uranium.
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the
Most copper ores contain <1% copper and most of the energy and reagents used to extract that copper are consumed by the gangue minerals. Considering this, it is critically important in any copper project to understand both the ore and the gangue mineralogy before developing or optimising the process circuit.

The copper ores, waste from the copper industry, phosphate rocks and phosphogypsum were considered as sources of uranium in these studies. Apart from uranium

Ore is processed through both trains in a variety of configurations. The predominant configuration is sequential flotation, where copper bearing minerals are recovered to a saleable copper concentrate, followed by re-activation and flotation of the pyrite which is leached with cyanide to recover gold.
Ore mined underground is hauled by an automated train system to crushing, storage and ore hoisting facilities. The processing plant consists of two grinding circuits in which high-quality copper concentrate is extracted from sulphide ore through a flotation extraction process.
Most copper ores contain <1% copper and most of the energy and reagents used to extract that copper are consumed by the gangue minerals. Considering this, it is critically important in any copper project to understand both the ore and the gangue mineralogy before developing or optimising the process circuit.

After treatment by flotation, the finely-crushed ore is leached with sulphuric acid to dissolve uranium and any remaining copper. The leach liquor is processed in the solvent extraction plant to separate the residual copper and uranium streams. Copper is recovered by electrowinning and uranium converted to yellowcake and calcined uranium oxide.
1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.
