In making sulfuric acid, the hot gases are first collected from the roasters, furnaces, and con-verters see box 8-B. The gases are cooled, cleaned through three series of dust collection systems to recover copper from the dust and prevent foul-ing of the acid plant, and then treated with sul-furic acid to remove any water vapor. Catalysts
Gold and silver are products of the copper mining and smelting process. They follow the same production pathway as our copper ore from the mine to the smelter. At the refinery, we lower copper anodes which contain gold and silver into an acid solution. Gold and silver drop off into the bottom of the tank as electrolytic slimes.

As the heart of the plant, these boilers are crucial to efficient energy creation. If impurities enter the boiler feedwater or corrosion develops inside the boiler, equipment can be damaged, the plant can experience unexpected downtime, and energy creation can be extremely ineffective.
Apr 19, 2019 A siliceous oxidized copper ore carrying from 1.5 to 2.0 per cent, metal may be profitably leached under favorable conditions there are no other metallurgical means known for commercially handling ore of that character and grade. Copper Leaching Practices. For centuries small amounts of copper have been recovered from acid mine-drainage waters.
Hydrochloric acid is always used in AARL systems with concentrations generally around 3 by volume. Acid washing is currently being done both in a separate vessel from the stripping column and in the elution vessel. Factors favoring acid washing in the elution vessel include 1 eliminating a carbon transfer which reduces gold losses from fine ...
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Apr 14, 2016 Copper Agitated Leaching and cementation process of copper problem The treatment of copper ores, both oxides and sulfides by means of flotation, hydrometallurgy or other processes has been well established for many years. Flotation has been applied generally to the treatment of sulfide ores, both in small and large scale operations.
The chemical cleaning of a boiler is a project fraught with danger and horror stories abound. For example, a few years ago a power boiler was cleaned with ammoniated EDTA ethylenediaminetetraacetic acid. The plant operators were unaware that chemical cleaning solution had found its way into the superheater and was not flushed out.
W.G. Davenport, in Encyclopedia of Materials Science and Technology, 2001 4 The Future. The major trend in copper smelting and converting is towards improved capture of the SO 2 that is evolved from oxidizing CuFeS 2 and other copper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used for leaching oxide and supergene sulfide ...
The sulphuric acid plant has been designed to capture 80 or more of the sulphur dioxide emissions from the copper smelter. The guaranteed conversion efficiency is 97.4 at nominal capacity. Although performance testing has not been fully completed, data collected to date indicates in excess of 97.4 for acid production rates less than the ...

In 2006 the Division produced 173,413 tonnes of copper anodes and 499,243 tonnes of sulfuric acid. The Chagres Smelter Division has approximately 500 workers, including company employees and external contractors for operations and projects.
Infrequently, copper plating usually the result of an improper acid cleaning operation may lead to pitting problems. Caustic Attack Caustic attack or caustic corrosion, as differentiated from caustic embrittlement, is encountered in boilers with demineralized water and most often occurs in phosphate-treated boilers where tube deposits form ...
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. In Latin America, the total is closer to 40 whereas in the United States the total is approaching 30.
The copper is purified to 99.99 by electrolysis. The production route described above shows the progression from a rock containing about 0.2 copper to a copper cathode of 99.99 purity. Leaching. Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid.
Oct 26, 2015 FB-1 CECEBE Furnace By-Pass System The conventional system for sulfur burning in a sulfuric acid plant consists of a sulfur furnace, a waste heat boiler and a jug valve in the by-pass line around the waste heat boiler. In the sulfur furnace, liquid
Nov 02, 2020 Sulfuric acid. Sulfuric acid is a toxic chemical used in copper mining. It is also a byproduct of many kinds of mining, mixing with water and heavy metals to form acid mine drainage. Sulfuric acid smells like rotten eggs. Contact with sulfuric acid can cause burns, blindness, and death.

gold or sulfuric acid copper. If a mining project involves the extraction of a few hundred million metric tons of mineral ore, then the mine project will generate a similar quantity of tailings. How a mining company disposes of this high-volume toxic waste material is one of the central questions that will determine whether
processing for copper removal and cyanide recovery is used. In 2015, a flotation plant was added to treat the tailings from the agitation leach plant before the tails are sent to the tailings dam. This plant produces a copper sulphide flotation concentrate and also recovers some of
plant andor full-scale plant. In the case of leaching and CIPCIL, such data are relatively easy to obtain for existing plants, assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant, such data are much more difficult to come by, particularly if the ore is from a deep underground mine.
