NEW CONTINUOUS SMELTING AND REFINING PROCESS FOR COPPER .
· Contimelt is a new twostage process for melting and refining copper. Compared to the traditional batchwise operated reverberatory refining furnace, Contimelt represents a continuous operation with a high melting/refining rate, saving energy and manhours and allowing close environmental control.
Refinery
Copper anodes and SS blanks are inserted in altenatively electrorefining cells. By applying direct current to this cell, copper in anode is dissolved and deposited onto the SSblank surface. Cu % in hode is more than %. By products at Refinery are anode slime and copper telluride.
Refining – Various Methods
Usually, it is a copper refining process against impurities. Firstly, the impure copper is kept in an anode furnace for two steps of refining. Next, iron and sulphur release in the form of iron oxide and sulphur oxide by blowing air. In this step, the iron oxides release from copper and gaseous sulphur oxide emits from furnace by offgas system.
Smelting and Refining Copper in Chile: The Importance of ...
Smelting and refining all the copper ore in Chile on the one hand helps to reduce global greenhouse gas (GHG) emissions (Sturla et al., 2020), but on the other hand, by concentrating this process in one country (in spite of 12 countries), greatly affects the
Copper Smelting Slag Recovery
Rotary Reverberatory Furnace Smelting. The furnace can be designed with effective working volume minimal, suitable for the recovery of anode slime, PMcontaining smelting slag, lead refining dross and all kinds of dust. It can also treat secondary material like scrap copper, WEEE/PCB/IC and etc. Lead Anode Slime.

Primary Copper Smelting
Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Process Description24 Mining produces ...

and smelting, converting, and refining the remaining 40 percent. Actual requirements vary widely depending on the mine characteristics and type of smelter, however. Table71 shows one estimate of energy requirementsin Btu equiva lents for a hypothetical copper operation. It is interesting to note that pollution control equals a
Copper Dross
Refining dross is the result of lead refining process where impurities like copper, tellurium, arsenicantimonytin, silver, zinc and bismuth in sequence from lead bullion. There are many types and composition of each type of dross varies and is subjected to specific refining steps and raw material contents.
Our process | Umicore Precious Metals Refining | Umicore
The main processing steps of the Precious Metals Operations are the smelter, the copper leaching and electrowinning plant and the precious metals refinery. The operations are designed in such a way that raw materials can enter the flowsheet at the most optimal process step, determined by their physical aspect, their analytical fingerprint and their (precious metals) value.
Focused on copper
Since completion of the Group restructuring on 31 October 2014 KAZ Minerals no longer carries out smelting and refining activities internally, instead sending copper concentrate directly to export markets or to external providers of smelting and refining services in Kazakhstan.
Copper extraction
Copper extraction refers to the methods used to obtain copper from its 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.. As in all mining operations, the ore must usually be beneficiated (concentrated).
copper processing
Roasting, smelting, and converting Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractorylined furnace of either the hearth or fluidizedbed type.
Copper
Copper. We are one of the world's largest producers and marketers of copper. In 2020, we produced million tonnes, and sold million tonnes through our marketing business. We mine and process copper ore in the key mining regions of Africa, Australia and South America. We source and recycle copper scrap in North America and Asia.
