A new generation of high-efficiency coarse and medium-fine crushers: CI5X series impact crushers
·For the recycling of copper scrap SMS group has developed a new generation of fire refining furnaces either tilting refining furnaces TRF or elliptical tilting refining furnaces ETRF
·The pyrometallurgical copper production route typically involves a three step process from feed to anode s melting converting and fire Two types of furnace are in use in the refining section the rotary furnace type dominates in primary copper production while secondary smelters tend to use hearth refining furnaces because they are more suitable for
·The metallized product of TBRC was used as the feed for Inco Pressure Carbonyl IPC process which produced high purity nickel pellets and powders In Canada CEPA 99 requires that in the future new smelters and refinery capture >96% SO 2; for copper lead and zinc facilities 99% capture is required This is dramatic progress toward
These types of copper scrap usually have to be refined to obtain the quality required Refinery brass has a minimum of % copper and a maximum of 5% iron; it consists of brass and bronze solids as well as alloyed and contaminated copper scrap Copper alloy scrap can be classified by type of alloy or by its end use
AMES Copper Group is committed to promoting sustainable practices and adhering to green initiatives in its operations While the company strives to implement environmentally responsible methods in copper manufacturing including recycling and purification processes this disclaimer recognizes that efforts to reduce environmental impact are ongoing
Copper smelter and refinery with a copper cathode production capacity of 70 000 tpa A precious metal plant is also integrated into the base metal operation to produce gold and silver The Ust Kamenogorsk metallurgical complex is able to process highly complex materials with high recoveries given by the integrated nature of the plant
Focusing on high demand of precious metal recovery and large treatment amount Metalcess offers solution of TBRC smelting lead distillation & gold metal extraction Anode slime is a byproduct of copper or lead electro refining process and found in electrolytic cell bottom or on the anode scrap surface The copper anode slime and lead
Refining dross is the result of lead refining process where impurities like copper tellurium arsenic antimony tin 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
·Metso copper refining technology covers the entire process based on highly proven equipment and pre engineered solutions Our technology enables sustainable and economically viable copper electrorefining for both new and existing operations Benefits • Complete copper refinery design covering tankhouse solution
4 ·Niihama Copper Refinery of Sumitomo Metal Mining Co Ltd which commenced the operation in 1919 is one of the Japan s custom copper and precious TBRC 2 and the BBOC have been developed for the Dore furnace The BBOC appeared attractive in the SMM s process on account of a easy control ofthe bath temperature oxygen efficiency of around
Copper Scrap Refining Furnace Copper scrap refining furnace is a wide range of furnaces Furnace for copper scrap has many types such as TBRC Anode furnace and etc CHMM is specialized in producing Anode furnace which is mainly used to refine the molten copper from upstream melting furnaces for copper scrap
·The capability to produce high quality copper wire from cheaper dirtier scrap can improve considerably the profitability of secondary copper refining furnaces The global depletion of easily accessible primary copper reserves from mined oxide/ sulphide concentrates has led to secondary copper processing assuming an ever increasing
·Several of the more recently built plants are using bath smelting with top submerged lance Isasmelt/Ausmelt technology or top blown rotary converters TBRC /Kaldo or a combination of submerged lance and TBRC for smelting and refining Processing and recycling of copper is extensively described in a recent publication by Langner Langner 2011
·the matte is slagged and removed before the copper blow phase In the copper blow phase most of the remaining sulfur is removed leaving only small traces to be removed during the fire refining process After converting the blister is sent to fire refining and the slag from the converter is usually sent to slag treatment for copper recovery
·The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining The anode plates are approximately 1m x 1m x in size and weigh 380 kg per plate
Used for smelting & converting various primary & secondary raw materials such as concentrates copper scrap anode slimes & e waste
·No less than 90% of copper containing ore extracted and processed by pyrometallurgical methods is currently subjected to electrolytic refining to obtain copper cathode Improvement in the electrolytic refining process of copper to obtain products for the electrotechnical industry can be related to the extraction of precious metals from copper
Focusing on high demand of precious metal recovery and large treatment amount Metalcess offers solution of TBRC smelting lead distillation & gold metal extraction Anode slime is a byproduct of copper or lead electro refining process and found in electrolytic cell bottom or on the anode scrap surface The copper anode slime and lead
·WEEE contains metals like copper silver gold selenium tellurium indium nickel tin and lead which build up in total to a value between 1 000 and 4 000 /t scrap depending on the commodity
The fire refining furnaces used for the anode production line are either tilting refining furnaces TRF or elliptic tilting refining furnaces ETRF optionally expanded with a top blown rotary converter TBRC Tilting refining furnaces are based on an improved scrap charging system and optionally semiautomatic skimming that keeps the
Recycling of copper scrap greatly reduces natural resource exploration as an alternative source of copper metallurgy and has big advantage in investment production cost and off gas treatment thus making the copper scrap smelting projects remunerative However due to the wide source range the copper scrap is classified as per its grade to be treated by different smelting
·utilizes one TBRC to treat a high grade copper concen trate More recently Boliden4 commissioned a copper TBRC at their Ronnskar smelter in Sweden Although it has an energy consumption higher than flash smelting processes the TBRC is a compact smelting unit which has a high degree of flexibility and can handle a relatively wide range
·Copper anode slime is a by product derived from electrolytic refining of blister copper which contains considerable amounts of multiple valuable elements such as Se Te Au Ag Pb and Pt group metals These metals are eventually deposited at the bottom of the refining tank as an insoluble phase [9 10] In recent years a treatment of closed
The fire refining furnaces used for the anode production line are either tilting refining furnaces TRF or elliptic tilting refining furnaces ETRF optionally expanded with a top blown rotary converter TBRC Tilting refining furnaces are based on an improved scrap charging system and optionally semiautomatic skimming that keeps the
