PT. Smelting applies Mitsubishi technology for copper smelting process. 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.
A basic flowsheet of smelting and refining can be found below [1, 2]: In a first step, smelting takes place in different types of furnaces depending on the raw …
The use of low grade, high impurity copper concentrate has made the copper smelting process increasingly complex. As the composition of copper slag changes, controlling slag characteristics is essential to maintain process efficiency and improve slag matte separation. Al2O3 is one of the major gangue elements in the …
The processes for pyrometallurgical smelting of copper sulfide concentrate include matte smelting, copper matte converting, pyro-refining, and electrolytic refining. Some specific low-iron copper concentrates can be smelted directly to blister copper without matte smelting, known as the directly to blister copper process. Matte-Making …
In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has copper.In these operations some of the copper is oxidized to cuprous oxide …
During copper matte smelting, a lag exists in the analysis of the smelting results, leading to the production parameters not being effectively adjusted in time. As the first smelting process in copper pyrometallurgy, the optimization of the amount of raw material, as well as the prediction and adjustment of slag and matte phases, has …
In the black copper route (secondary copper smelting), crude copper is produced during a reduction process and is refined by oxidation in a converter.
The structure housing the furnace may be made of steel, but the furnace itself is made of refractory brick. Refractory bricks are made from clays with super high melting temperatures and insulating properties that make …
