Jun 19, 2017 Glencore Technology’s ISASMELT™ provides an innovative, high intensity, yet low cost submerged lance smelting process that is simple to operate which can be used for a range of applications including copper and lead smelting as well as recycling. The process is fully enclosed, and operates in regions with some of the toughest emission standards. The proven technology has been

Isasmelt process | metallurgy | Britannica

In the Isasmelt process, a gas or air lance is brought in through the top of a furnace and its tip submerged in the sulfide concentrate. A blast from the lance produces a turbulent bath in which the concentrates are oxidized to produce a high-lead slag

ISASMELT Process Technology :: Total Materia Article

In the Isasmelt process for copper smelting, copper ores are reacted with oxygen and silica to form a two phase liquid mixture of copper matte and slag in the Isasmelt furnace. This mixture is then settled in a rotary holding furnace (RHF) where the mixture is fed in at one end and exits through side ports close to the opposite end of the furnace

Glencore Technology’s ISASMELT™ provides an innovative, high intensity, yet low cost submerged lance smelting process. It is simple to operate which can be used for a range of applications including copper and lead smelting as well as recycling

Thermochemical Modelling of the Isasmelt Process

The composition of melts produced in the Isasmelt process are closely approximated by an equilibrium model. Differences arise with several reaction zones present in the furnace, and the difficulty of matching published solution models with plant conditions. 1

The ISASMELT™ process is a top submerged lance (TSL) bath smelting technology which has been developed and optimized over the last 25 years

Toxicity characterization and long-term stability studies

Feb 01, 2008 The ISASMELT process of MIM technologies, Australia has been adopted at M/S Sterlite Industries, Tuticorin, India. In this process, the charge comprising of copper concentrate mixed with quartz, coal/coke, pig iron and limestone is charged into the feed port at the top of the ISA-furnace

Isaconvert Continuous Converting of Nickel PGM Mattes

Abstract – The ISASMELT™ top submerged lance (TSL) bath smelting process was developed in Mount Isa, Australia by Mount Isa Mines Limited (now a subsidiary of Xstrata plc) during the 1980s. By the end of 2011, the total installed capacity of the ISASMELT™ technology will exceed 9

Smelting - an overview | ScienceDirect Topics

Smelting to give the metals involves metallothermic reduction of fluorides or oxides, or electrochemical methods. Metal oxides are converted to fluorides by HF/Ar and purified by melting in an HF/Ar atmosphere. The fluorides are then reduced by the more electropositive calcium metal

ISASMELT - Infogalactic: the planetary knowledge core

The ISASMELT process is an energy-efficient smelting process that was jointly developed from the 1970s to the 1990s by Mount Isa Mines Limited (a subsidiary of MIM Holdings Limited and now part of Glencore Xstrata plc) and the Australian government’s Commonwealth Scientific and Industrial Research Organisation ( CSIRO ). It has relatively low capital and operating costs for a smelting process

ISASMELT™ AT MUFULIRA – INCREASED FLEXIBILITY ON

ISASMELT™ technology. INTRODUCTION The ISASMELT™ process, based on the Sirosmelt lance invented by the CSIRO and commercialised by Mount Isa Mines (MIM) over the last three decades, was originally intended to be used for lead concentrate smelting. MIM soon found it to be a suitable smelting technology for copper smelting [1,2] as well

Isasmelt technology—current status and future

The Isasmelt process was originally developed for primary lead smelting, the development occurring in collaboration with CSIRO, the Australian Government research organisation, via laboratory testwork at CSIRO and pilot plant and demonstration scale plants at

Thermodynamic simulation model of the isasmelt process

A computer model has been constructed to simulate thermodynamically the behavior of the minor elements Zn, Pb, As, Sb, and Bi as well as the major elements Cu, Fe, Si, O, and S in the Isasmelt process, producing copper matte. The model is based on the new concept that there are two independent reaction sites in a slag bath: one for fast oxidation and the other for slow reduction. The
