The lead plant treats sulphide concentrates by sintering, shaft furnace reduction, two stage liquation of copper and alkaline oxidation of impurities. Extractive metallurgy In 2011, eighty percent (80%) of the 64 million metric tonnes of DRI produced in the world via the shaft furnace route was produced utilizing the MIDREX[R] Direct Reduction ...
The Outotec Anode Furnace is a cylindrical horizontal rotary furnace used for refining the blister copper before anode casting. The furnace is operated in batches. First, sulfur is removed by oxidation, followed by oxygen removal by reduction.
The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage).

These flakes can be smelted in a furnace to obtain a unit of the ore's material. Each stage in the extractor has a 50% chance of doubling the output. The machine's requirements are complex and vary from stage to stage, but a supply of water and 512 Nm of torque at 8192 rad/s will run all four stages.

ROASTING oThe concentrated ore is then roasted in a furnace between 500oC and 700 C in the presence of a current of air. Sulphur is oxidized to SO
Extraction and refining. The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.
The price of steelmaking raw materials in China rose for a second session on Monday on optimism that steel mills will replenish stockpiles as steel production increases and as iron ore inventories ...
Induction Furnaces: We can satisfy your production requirements! ITC induction melting furnaces are designed for maximum electrical efficiency using heavy walled, high electrically conductive copper tubing. The furnaces can be used with ceramic (nonconductive) crucibles or conductive crucibles such as graphite, clay graphite or silicon carbide.

Copper concentrate is the first product of the copper production line and is usually produced by a smelting process, which can be undertaken in a variety of furnaces. The product of this smelting stage is a mixture of roughly equal parts of copper, iron and sulfur that contains around 30% copper.
The present topic "Metal Smelting and Furnace Tapping" provides JOM readers with an interesting update on these hightemperature pyrometallurgical processes.. Metal smelting is a fundamental process in pyrometallurgical metal production.
