As a representative pyro-metallurgical technology, the flash smelting process effectively utilizes the large surface of concentrate particles to strengthen the smelting intensity. This process, characterized by a high operational rate and automated equipment, ensures over 50% production of the world's primary copper [1,2].

For the corresponding bath smelting, the physicochemical changes of the smelting process mainly occur in the bath with the melt as the continuous medium. Flash smelting is mainly classified into two types, i.e., Outotec (Outokumpu) flash smelting process and INCO flash smelting process, according to the different furnace types.

The use of automatic control has the potential of maintaining high performance level for copper flash smelting process. Without changing the existing smelting equipment, the model-based operational parameters optimization methods have played an important role in attaining the smelting objectives and have gained growing interest during recent years [5].

ABSTRACT Improving metal–slag separation in pyrometallurgical processes is increasingly important. Due to the harsh conditions, direct observations of the molten phases behavior in the settler of the Outotec Flash Smelting Furnace (FSF) are not possible and the ways to improve metal settling can only be studied by simulation and modeling. This study focuses …

1. Introduction. As a main production method employed for extracting copper from its sulphide ore, the copper flash smelting process is widely used throughout the world, which accounts for about 50% of global capacity for primary copper production (Najdenov, Raić & Kokeza, 2012).The complexity and variety of the copper flash smelting process is inherently …

The effectivity of present copper smelting technologies have their roots in industrial and laboratory-scale experience accumulated over the past decades. Since early '60s, the tools for improving the processing conditions and smelting vessel design included scale modelling and manual computing of homogeneous multicomponent equilibria.

A brief history of the development of the Kivcet flash smelting process is presented. The broad scope of the process with an ability to treat high grade lead sulphide concentrates, as well as oxidized lead-zinc residues, is emphasized. Fine coal in the charge serves two purposes, one as auxiliary fuel and the other as a pre-reductan for ferric iron in residues. Current Kivcet …

Copper flash smelting is the main process method for copper extracting. It is a complex and multi-phase physical and chemical change process with the characteristics of multiple variable, nonlinearity, delayed detection of product quality. Matte grade is a key indicator reflecting the stability of flash furnace smelting conditions, which directly affect the product quality and …

During the smelting process, the speciation of arsenic is very complicated. Due to the micro "smelting pool" mechanism of flash smelting, the gas-solid-liquid phases are sufficiently interacted in the smelting shaft. This is also the reason for the high contents of copper and arsenic in flash smelting slag.
