Typically, blister copper is then fire-refined in an anode furnace, cast into "anodes", and sent to an electrolytic refinery for further impurity elimination. Roasting is performed in copper smelters prior to charging reverberatory furnaces. In roasting, charge material of copper concentrate mixed with a siliceous flux (often a low-grade copper ...

The furnace mouth for Kumera Anode Furnaces is supplied with water-cooled cooling elements to increase the life-time and to enhance the operability of the mouth.
Uranium extraction: the key process J drivers
encountered flowsheet for uranium processing comprises conventional mining followed by comminution, acid leaching, solid/liquid separation, SX purification and finally precipi-tation/recovery as indicated in Figure 1. A high ore carbonate content, hence high acid consumption, may dictate the use of alkaline leaching, and some guidelines for the ...

Uranium processing: A review of current methods and technology
Uranium is the basis of the nuclear power industry as well as military weapons programs. The unique position of uranium in these activities, the increasing ore grades that have been discovered, and increasing environmental concerns have very much influenced recent process developments. This article presents a review of the current status of uranium …
Uranium (U) Ore | Minerals, Formation, Occurrence, Deposits
Uranium ore refers to naturally occurring rock or mineral deposits that contain a sufficient concentration of uranium, a radioactive element, to make its extraction economically viable. Uranium is a relatively rare element and is typically found in trace amounts in the Earth's crust. Uranium ore is typically mined and processed to extract …

Uranium Recovery (Extraction) Methods | NRC.gov
Alternatively, uranium may be recovered from the ore using a heap leach process. In the heap leach process, the ore is placed on a engineered barrier and sprayed with acid. The uranium dissolves into solution and is collected at the engineered barrier. The solution undergoes additional chemical processing to produce "yellowcake".
New developments in fire refining
The conventional fire refining process consists of an anode furnace capable of treating blister to anode copper through oxidation by air and reduction by reductant e.g. natural gas, LPG or diesel. However, in most cases controlling of the refining cycle is not optimized and Outotec has identified several areas for improvement such as:

The Extraction of Copper
Any metal in the impure anode which is below copper in the electrochemical series (reactivity series) does not go into solution as ions. It stays as a metal and falls to the bottom of the cell as an "anode sludge" together with any unreactive material left over from the ore. The anode sludge will contain valuable metals such as silver and gold.
