A process for treating anode slimes originating from copper, lead or nickel electrorefining to recover the precious metals contained therein is disclosed. The process comprises the steps of charging the slimes into a tiltable and rotatable top blown rotary converter (TBRC), smelting the slimes in the TBRC while it is rotated on an axis inclined to the horizontal to form a slag phase and a ...
The TBRC is a high-speed, rotating vessel fired by an oxy-fuel lances. Both the lancing technique and the rotation of the vessel provide remarkable augmentation in mass transfer rates compared with reverberatory or rotary furnaces. TBRC's can be used for smelting and refining in the same vessel.
Originally applied to the refining of iron into steel, with most installations in the 1960s, the process is (2014) used primarily to refine non ferrous metals, typically copper. In that field, it is often named TBRC, or Top Blown Rotary Converter .
Metalcess provides high grade copper scrap directly producing hot-rolled electrical grade copper rod, and for low grade copper scrap providing TBRC smelting, copper electrorefining to produce LME-1 copper .
The MAERZ TBRC (Top Blown Rotary Converter) is a general purpose unit for the copper and precious metals production. A central feature of the Top Blown Rotary Converter (TBRC) is the constantly high melting and refining efficiency.
Copper, nickel, tin, lead and the precious metals contained in the raw materials are enriched in an alloy with a copper content of about 80 %. In a top blown rotary converter (TBRC) the copper content is further enriched to 95 % and tin and lead are separated into a slag.
the TBRC is its consistently high melting and refining efficiency. Typical input ma terials are copper scrap, WEEE scrap of different qualities, especially printed cir cuit boards, dust, slag, lead production al slime from copper electrolysis. Depend ing on the purpose, different water-cooled lances are used for melting, oxidation, re
At Vale we use them in the nickel refining process. Every few years, one of the TBRCs has to be removed from service so that the two riding rings - the parts that support and drive the shell - can be replaced. "On average a TBRC shell change takes seven days," said Brian e, senior engineer, maintenance, applied engineering, at Copper Cliff.

Copper, Nickel, Lead, And Zinc Mining Global Market Report 2019 - The Copper, Nickel, Lead, And Zinc Mining market size is expected to reach $160 billion by 2022, significantly growing at a CAGR of around 3% during the forecast period. The growth in the Copper, Nickel, Lead, And Zinc Mining market is due to growing demand for power cables and ...
A copper converting process starting with white metal or a mixture of white metal and metallic copper in which oxidizing gas contacts the molten copper mass either at or near the top surface of the molten mass while the mass is sparged with an inert gas from at or near the bottom of the mass and sparging is continued after contact with the oxidizing gas ceases.

The top-blown rotary converter (TBRC) is a general-purpose unit for copper and precious metals production. A central feature of the TBRC is the constantly high-melting and refining efficiency. For precious metals refining, input materials can include precious metal–containing ores and scrap alloys from other non-ferrous processes.

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)
Copper Furnace Furnace Scrap MAERZ Direct-To-Wire® Technology comprises the following production steps: Charging and melting of copper scrap with a minimum copper content of 92%. Refining (oxidation – deslagging – reduction) of molten copper to FRHC (Fire Refined High Conductivity) copper .
All the copper anodes from Noranda's Horne and Gasp smelters are sent to CCR for refining. When Martin Guilbert, superintendent of engineering and central maintenance, showed CMJ around the refinery in mid-April, the plant was expecting its first shipment of anodes from the Altonorte smelter for testing.
Plants for copper winning from secondary raw material in their conventional structure are operating with the aggregates blast furnace, converter, refining furnace, and refining electrolysis. Between the single operation steps there are necessarily considerable material reverse runnings which cause a loss of metal and additional energy.

No. 1 copper scrap has a minimum of 99% copper and is often just remelted. No. 2 copper consists of unalloyed scrap, with a copper content of at least 94% with a nominal content of 96% Cu. Light copper scrap contains between 88% and 92% copper. These types of copper scrap usually have to be refined to obtain the quality required.
The Bottom-blown Oxygen Converter or BBOC is a smelting furnace developed by the staff at Britannia Refined Metals Limited ("BRM"), a British subsidiary of MIM Holdings Limited (which is now part of the Glencore group of companies).
