Mar 18, 2015· After a marked improvement in energy consumption in copper smelting during the past few decades, technology development has been slowing down in the Americas and in Europe. Innovation, however, is still required to further reduce energy consumption while complying with stringent environmental regulations.
Copper and Ewaste Recycling Theory and Industrial Practice ... Environmental benchmark in copper smelting ... Less energy (up to 85% lower) ...
Beginning in the mid 1980s a new technology, commonly known as the leachsolvent extractionelectrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process.
Global Industrial Energy Efficiency Benchmarking: An Energy Policy Tool The analysis shows the existence of a worldwide potential to save 31 EJ a year if all the processes reviewed were to operate at the level of the international benchmark. Excluding feedstock use, this is equivalent to a worldwide improvement potential of 26%, comprising a
The majority of the world''s primary copper originates in sulfide minerals, such as chalcopyrite (CuFeS2) and chalcocite (Cu2S). Flash smelting is one pyrometallurgical process for smelting metal sulfide concentrates. Forming of hard and dense accretions in the Copper Flash Smelting process is .
Hong Kong — Copper concentrate supply in China stayed tight this week, with some major Chinese smelters having followed the benchmark treatment and refining charges as settled by Chinese copper producer Jiangxi Copper and copper miner FreeportMcMoRan for 2017 at fees of /mt and cents/lb in midNovember, Chinese brokerage Mailyard Futures in Hubei Province said in its copper ...
smelting technology, Outotec also delivered basic and detailed engineering for the facilities. CASE STUDY: A NEW BENCHMARK FOR SUSTAINABLE COPPER PRODUCTION IN CHINA Outotec''s complete Flash Smelting and Flash Converting solution and process design expertise ensures excellent quality, availability, and environmental
Being an energyintensive industry, the energy usage pattern in the nonferrous metal industry merits close observation with the intention to bring down specific energy consumption for all metals. United Nations Industrial Development Organization (UNIDO) has taken up extensive programmes for international benchmarking, based on data available from individual industries of various countries.
copper production can be ensured for longer period of time The aim is to reduce operation costs (especially energy costs) by increasing the whole efficiency of the process including on line availability and long campaign life Today with high copper prices the recovery of copper is more and more important especially for custom smelters
Energy costs include electricity and other fuels such as natural gas, fuel oil, coal or coke used in the facilities. Copper smelters are high consumers of energy, although to a much lesser extent than the aluminium ones. Copper refineries are also power intensive processes. The major source of energy in electrolytic zinc smelters is electricity.
OUTOTEC SMELTING SOLUTIONS FOR THE PGM INDUSTRY L. Aspola Outotec R. Matusewicz Outotec K. Haavanlammi Outotec S. Hughes Outotec Abstract The platinum group metals (PGMs), ruthenium, rhodium, palladium, osmium, iridium, and platinum, are typically found in association with each other, but also importantly, with nickel and copper.
Energy and Environmental Profile of the Mining Industry RCRA special waste. Special wastes are excluded from the RCRA statute. The slags from some smelting furnaces are higher in copper content than the original ores taken from the mines. Therefore, they may be sent to a concentrator for copper .
The paper analyzed the energy system of lead smelting enterprises, using the process of SKS (Shui Kou Shan) lead smelting. The SKS lead smelting process is a lead smelting ... like copper, lead and so on [13]. Research on the coupling model of SKS Lead Smelting Process helps recognizing the association between material flow and energy flow in each
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Nov 22, 2018· From that perspective, the 2019 benchmark is signalling both that mine supply is going to drop a gear again and that new Chinese capacity will mitigate against the smelter bottleneck that has ...

Nov 23, 2015· Introduction. Copper (Cu), owing to its excellent thermal and electrical conductivity, high ductility, corrosion resistance, and ease of recycling, is an essential material in modern society, used in electronics, telecommunication, energy, construction, and the automotive industries.
Environmental Impacts of EnergyEfficient Pyrometallurgical Copper Smelting Technologies The Consequences of Technological Changes from 2010 to 2050 Joanna Kulczycka, Łukasz Lelek, Anna Lewandowska, Herbert Wirth, and Joseph D. Bergesen Summary The article analyzes and discusses the environmental and natural resource impacts, benefits,
A unique aspect of the smelting process is that most of the energy for smelting the copper is provided by the oxidation of iron and sulfur in the feed materials. In spite of this energy efficiency, the smelter still requires large quantities of fossil fuel and electric power.
