Kennecott produces about one million tonnes of sulphuric acid each year as a product of the smelting process. The sulphuric acid is delivered to gold, copper, uranium, and beryllium metal producers, fertiliser producers, chemical manufacturers, power plants, steel companies, farmers, and companies involved in water treatment across the US.
The Product Sulfuric acid is a key element in the production of fertilizer (phosphates and ammonium sulfate) which is its primary use (approximately 65% of total consumption). Sulfuric acid is also used in the mining industry for leaching of copper, nickel, uranium and other elements from ores (approximately 15% of total consumption).
NRS-Import Sulfuric acid: a dangerous mining aid. Sulfuric acid is used to leach copper from the ground. But the method comes with considerable risks for the environment because of contamination ...
Sulphuric Acid. We recover sulphur in our production processes to produce a significant quantity of high purity sulphuric acid. Sulphuric acid is a vital commodity in any modern national economy. In fact it's so widely used, its consumption rate – like steel production or electricity power – is a good barometer of a nation's prosperity.
Case Study: Sulfuric Acid Pipeline. AuCom soft starters improve safety for Chilean copper mining industry.. Northern Chile is home to some of largest copper mines in the world, but the desert conditions, high altitude and extreme temperatures make road transport extremely dangerous.
Sulphuric acid is an important industrial chemical which is used in the manufacturing processes of many goods over a wide range of applications. Sulfuric acid used in pulp and paper industry for chlorine dioxide generation, tall oil splitting and pH-adjustments. Over one million tons of sulphuric ...
The papers in this issue focus on sulfuric acid. Sulfuric acid has become an integral part of the mining industry and today there are more sulfuric acid plants operated in the mining industry than in the chemical industry in South Africa. This revolution took place in the 1950s with the advent of the uranium extraction and recovery process.
It utilizes a powerful and regenerable oxidant, nitric acid, to completely (99%) leach copper and other heavy metals from all sulfide concentrates. It takes advantage of sulfuric acid process characteristics by rejecting iron as jarosite and recovering cathode copper directly from purified pregnant liquor. By-product metals are recoverable.
Jan 12, 2017· In a like manner, efforts are being made to provide a more continuous flow of sulfurous gas from the converters, to reduce excess air infiltration which dilute gas to the acid plant, to reduce excess loss of sulfur into the smelter building through hood and flue leakage, and to improve overall knowledge of sulfuric acid production in ...
The blister copper anodes are immersed in an electrolyte containing copper sulfate and sulfuric acid. Pure copper cathodes are arranged between the blister copper anodes and a current of over 200A passes through the solution. This is driven by a low voltage of about 1.3V and so the process is safe. What happens in electrolysis?

Copper is a soft, but tough metal, and it is an excellent conductor of heat and electricity. Copper is predominantly used in building construction, however other significant end use markets include electrical and electronic products, transportation equipment, consumer products and .
This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores, as high as 1,000 kg of acid per tonne of ore, but 500 kg is more common.
Our qualified equipment for mining and metal and mineral processing allows us to comply with all requirements in these industries. We offer EPC companies, operators, and end-users our complete portfolio of high-end metering, process and centrifugal pumps and pumping systems.
Sulphuric dioxide gas is created in smelting copper process and is converted sulphuric acid which is used in some of the smelting processes or sold as a by-product. Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace.
This chemical reaction produces acid mine drainage (AMD), a pollutant that is present at many abandoned mine sites. Learn more about abandoned mine drainage. Copper mining waste storage piles may be as large as 1,000 acres and typically include three types of waste; tailings, dump and heap leach wastes, and waste rock and overburden.
The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off
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.
Copper extraction refers to the methods used to obtain copper from its ores.The 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.

In this experiment an insoluble metal oxide is reacted with a dilute acid to form a soluble salt. Copper(II) oxide, a black solid, and colourless dilute sulfuric acid ...
Acid Storage. The large storage-tank for 66° B. acid is 8 feet in diameter and 8 feet high, lined with 10-pound lead. It holds about 46,000 pounds of 66° sulphuric acid. The small tank is the old Roessler converter 4 feet in diameter and 6 feet high, and holds about 8000 pounds.
The bottom layer of mostly copper and some iron is called matte. The Acid Plant Sulfur dioxide gas from the flash furnace is captured and combined with water in an adjacent acid plant to produce sulfuric acid.The acid is sold as a by-product to chemical manufacturers in the United States.
