Thus, to avoid this wastage and improve production efficiency, EGA operators of the carbon anode furnace
will use the computational tool developed through our research collaboration to help identify optimal parameters such as temperature of the furnace and time spent baking that will lead to high quality anodes.
The series II sulfuric acid system and the bismuth recovery system from converter smelting gas were completed and put into production, the smelting (refining) main workshop building (including the ancillary span was completed, installation of the 4# converter (major equipment for smelting) and the anode furnace
also commenced, and the construction of the converter heat recovery furnace, anode furnace
disc casting machine and series III oxygen station was basically completed and gradually progressed to equipment installation.
Some specific topics include heat exchange within the working space of an electric nickel anode refining furnace, new casting methods for anode copper, pyrometallurgical refining of copper in an anode furnace
, and minor element control by vacuum calcination and recycling of copper smelter dust.
It's believed a malfunction in the number two anode furnace
resulted in a spill of blister copper.
SEALED tenders in triplicate are invited from experienced & reputed contractors, for the mentioned jobs, in two part bids in two separate envelops having following pre-qualification A) REFRACTORY LINING CONTRACTOR HAVING AT LEAST TWO YEARS EXPERIENCE OF REFRACTORY LINING JOB IN COPPER INDUSTRY, PYROMETALLURGICAL PLANT LIKE FLASH FURNACE, SLAG CLEANING FURNACE, DRYER, CONVERTER, ANODE FURNACE
, LAUNDERS AND SPOON ETC.
The continuous flash converting process replaces the conventional batch type converting where the blister is brought to the anode furnace
via a ladle.
This latest expansion cost $A88 million and included the sinking of the new Robinson shaft, the installation of Australia's largest autogenous mill, additions to the flotation sections, two new CCD thickeners, an electric slag-cleaning furnace, a new anode furnace
gas cleaning plant, additional electro-refining cells and new evaporation ponds.
CSIRO first applied the Sirosmelt lance to tin smelting and fuming but in the late 1970s also applied it to lead slag reduction, copper concentrate smelting, and reduction of copper anode furnace
slag and converter slag (the latter two in conjunction with MIM).
Jinlong Copper has been using Praxair s patented oxy-fuel burner applications technology, Dilute Oxygen Combustion, in its anode furnace
for its high flame luminosity, wide flame coverage and extremely efficient heat transfer characteristics to boost energy efficiency and decrease emissions.
The blister copper is processed further in the anode furnaces
to turn out refined copper ready to be mold into copper strips by the machine of Hazelett Twin Belt Caster.
