CONTACT PROCESS Sulfuric acid is one of the most important industrial chemicals Outline three uses of sulfuric acid in industry 1. The major use of sulfuric acid in Australia is in the manufacture of fertilizers such as ammonium sulfate and superphosphate. Superphosphate is produced by reacting sulfuric acid with rock phosphate.
Sulfuric acid heap leaching of nickel. The technique is an acid heap leaching process like that of the copper method in that it uses sulfuric acid instead of cyanide solution to liquefy the target minerals from crushed ore. The process has been urbanized by European Nickel PLC for the rock laterite deposits of Turkey and the Balkans.
Energy and Environmental Profile of the U.S. Mining Industry 5.1 Process Overview 5.1.1 Copper Ore Mining Copper is commonly extracted from surface, underground and increasingly, from in situ operations. In 2000, the principal mining States, in descending order, Arizona, Utah, New Mexico, and Montana, accounted for 99 percent of domestic ...
Apr 26, 2012· The manufacture of sulfuric acid using the Contact process.
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

Sulfur is obtained from underground sources using the Frasch mining process. ... Like all the reactions involved in the production of sulfuric acid, this process is exothermic in ... the operating temperature of the absorber, gas flow rates, and concentrations.
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.
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.

copper L/SX/EW operation, the Bluebird plan of Ranchers Exploration and Development Corporation, came on line1. Copper recovery by L/SX/EX in 1968 In 1968 there were only two widely practiced copper leaching processes using dilute sulphuric acid. The first process, vat leaching of high-grade copper oxide ore followed by EW of
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?
98.5 –99 % sulfuric acid is a good absorber of SO 3 (g) lined with acid proof bricks with ceramic packing with concacid flowing over it allows for SO 3 (g) to have close contact with the concacid concentrated acid is withdrawn and portion going back into tower is diluted with …
Shalina Resources owns and operates two sulphuric acid plants. The first acid plant was commissioned in 2005 with a capacity of 100tpd at Usoke Ave. The sulphuric acid produced at the Usoke compound is used in the leaching of mined ore for the production of copper cathodes and cobalt carbonate.

The more sulfuric acid you add, the better is your throwing power, for example a usual copper electrolyte contains about 60 g/l Sulfuric acid, a copper electrolyte for plating printed circuit, which have very small holes to plate in, contains about 220 g/l Sulphuric acid.
Copper extraction Wikipedia. Such oxide ores are usually leached by sulfuric acid, usually in a heap leaching or dump leaching process to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate in solution.

Jan 14, 2019· Immersed in a tank of copper sulfate and sulphuric acid, along with a pure copper cathode starter sheet, the blister copper becomes the anode in a galvanic cell. Stainless steel cathode blanks are also used at some refineries, such as Rio Tinto's Kennecott Copper Mine in Utah.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.
are useful in the leaching process and in the design of copper sulfate pentahydrate crystallization plants from the leaching process using seawater by means of the addition of sulfuric acid. Keywords: Seawater; Copper sulfate; Sulfuric acid. INTRODUCTION The most important economic activity in Chile is mining.
sulphuric acid that treat alkylation waste acid. The plants are usually located on the refinery site which avoids the need to transport the waste acid to the processing facility. A regeneration plant will also process spent acid from other nearby refineries. The acid regeneration plant can also process hydrogen sulphide (H2S) gas
Each process is unique which dictates that the gas be treated in different ways in order to remove impurities and treat the SO 2 in the gas. The following table list the type of metallurgical operation and the type of hot gas cleaning employed prior to sending the gas to a sulphuric acid plant or in some cases an alternate treament method.

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.

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
