The First commercial application began at Mitsubishi Materials Corporation,Naoshima,Japan in 1991 with a capacity of 270,000 tpy In 2005 it came to India when Hindalco Birla Copper established a new Mitsubishi Process line at Dahej,Gujarat with a capacity of 250,000 tpy copper, in addition to their conventional flash smelter PS converters ...
Return to Menu . PROCESS DESCRIPTION. The figure shown below schematically describes the Mitsubishi Process, illustrating its sequence of continuous and controlled smelting of copper concentrates, coal, and flux the separation of copper matte and discard slag the continuous conversion of copper matte to blister copper and finally, the continuous delivery of blister copper to the anode
Mitsubishi Process Pilot plant of Mitsubishi process by 72TD in 1968 Basic idea Smelting and converting in separate furnace Two steps Transportation through launders
New Mitsubishi Process plant was established, with a design capacity of 204,000 mtpy copper. This new Mitsubishi Process plant has, as planned, successfully rationalized Naoshimas copper operations by completely replacing the older conventional ReverbP-S smelter, the original Mitsubishi Process plant, and their respective anode casting plants.

The Mitsubishi Continuous Copper Smelting and Converting Process is currently employed at Naoshima in Japan, Gresik in Indonesia, Onsan in Korea and Timmins in Canada 1. The process has many advantages, for example, its slag loss of copper can be kept at a very low
The Mitsubishi process is copper continuous smelting and converting technology using three furnaces. The three furnaces are linked with covered launders, through which all the molten materials are continuously transferred by gravity. Copper concentrate Cu 30, S 30, Fe 25, Gangue minerals 15 is fed through lance pipe with oxygen ...

The Mitsubishi process for the continuous smelting and converting of copper holds many advantages over conventional processes, where reactions must be conducted in numerous steps and melts must be tapped frequently from the furnaces. The furnaces operate like steady-state reactors with constant melt volume, composition, and temperature. Therefore, optimal control of the process is ...
Jan 01, 2014 The Mitsubishi continuous copper smelting process that combines the matte smelting and converting steps into one continuous coupled operation is then discussed. Finally, some observation on the industry trends for copper production is presented. The use and degradation of refractory linings in copper furnaces are discussed in Section 2.1.3 ...

Jan 01, 2019 The Mitsubishi process is the only system for continuous production of blister copper from copper concentrates and consists of 3 furnaces connected by enclosed launders those ensure the minimum emission of fugitives. In a smelting furnace S-furnace copper concentrates are fed with flux, oxygen-enriched air to form a mixture of slag and matte ...
Mitsubishi Process The process is a continuous, multi-step process which produces blister copper from concentrates in three interconnecting furnaces. Concentrate and oxygen-enriched air 30-35 O 2 enter the smelting furnace through vertical lances and are smelted to produce a matte of 65 to 69 Cu and low-copper slag.
