Aug 14, 2012· Sulfuric acid (H 2 SO 4) is important in the production of fertilizers (e.g., ammonium sulfate (sulfate of ammonia), (NH 4) 2 SO 4, and superphosphate, Ca(H 2 PO 4) 2, which is formed when rock phosphate is treated with sulfuric acid). Sulfuric acid is manufactured at the site using the well-known contact process.
Sulfuric Acid Environmental Profile596 Кб. Sulfuric acid is a corrosive, clear, colorless, odorless, oily liquid that is the largest-volume industrial chemical produced in the world and is the most commonly used strong acid.Ore from the mine is upgraded using a flotation process to produce copper concentrate.

Sulfur is a component in the production of Sulfuric acid and Explosives, both of which are also intermediate products used in higher-level recipes. Sulfur is a solid item in a chain of otherwise fluid-based manufacturing: Crude oil → Petroleum gas → Sulfur → Sulfuric acid. It is thus recommended to keep an eye on sulfur production early ...
A process of leaching silicated zinc ores with sulfuric acid in which the ore is reacted at elevated temperature with at least a stoichiometric amount of sulfuric acid, treating products of the reaction with a predetermined quantity of hot water, filtering the zinc sulfate solution from precipitated silica, washing with a further predetermined quantity of hot water (the total amount of hot ...
sulfuric acid, nitric acid, and lead batteries. Exposure also occurs during copper smelting, and pickling and other acid treatment of metals (Suresh, 2009). Minor uses of sulfuric acid include applica-tions in petroleum refining, mining, metallurgy, and ore processing, in the synthesis of inorganic and organic chemicals, synthetic rubber and ...
To start, "ore of pure metal" is a bit contradictory. Ore as a term implies that the substance is a metal-containing compound, which is why ores need to be either thermally or chemically (or both) processed in order to extract the metal. For examp...
Sulfuric acid is a very important commodity chemical, and indeed, a nation's sulfuric acid production is a good indicator of its industrial strength. It is widely produced with different methods, such as contact process, wet sulfuric acid process, lead chamber process and some other methods.
Abstract: The leaching of dolomitic-copper ore using sulphuric acid under controlled conditions was studied with a view to evaluating the economic value and the effect of ore pulverisation, particle size, temperature and pH on the recovery of copper from chalcopyrite. The samples were ground and mixed with water and sulphuric acid to form an acid
Sulfuric Acid is a liquid that is used to create batteries and processing units. It is converted, by the chemical plant, from sulfur, water, and iron plates. It must also be piped into electric mining drills to mine Uranium ore.
This chart shows how sulfuric acid is used to extract copper. The main difference between this and the 'pyroprocessing' of sulfide ores is that no heat is used. The pictures below show the process sequence. 1. Crushed ore is carefully dumped into a leakproof lined valley created in an open pit mine. Crushed ore .
Mar 21, 2012· Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.
Oct 02, 2009· We use sulfuric acid in just about everything we consume. It is used in batteries, paint, fertilizer, ore processing, steel production and water treatment. It is a building block for a number of ...

Nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. The hydrometallurgical process for laterite ore can use sulfuric acid or ...
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 ...
New sulfuric acid plants based on elemental sulfur as feed are designed to recover much more energy from the process than was heretofore economically feasible, because energy prices have risen much more rapidly than construction costs during the last decade.
Sulfuric acid – Manufacturing process of Sulfuric acid : Sulfuric acid is the largest-volume industrial chemical produced in the world (200 million tons per year). Concentrated sulfuric acid (93-98 %) is used in the manufacture of fertilizers, explosives, dyes, and petroleum products.
Nov 24, 2015· How can simple extraction of copper ore A simple way of copper ore extraction for the analysis of the content of copper ores in the rocks can be done by using a solution of concentrated sulfuric acid.
The flowsheet discussed in this study is for treatment of 100 tons per day oxide-sulfide copper ore by the leaching process using sulfuric acid-ferric sulfate solvent. This flowsheet would also be suitable for a larger tonnage by proper sizing of the various units of equipment.
This process is called the contact process. Uses. Sulfuric acid has many uses. World production in 2001 was 165 million tons, worth about $8 billion US dollars. Uses include ore processing, fertilizer manufacturing, oil refining, wastewater processing, lead acid batteries, and combining
PDF | The leaching of uranium from Sella uranium ore using sulfuric acid solution has been studied. The effect of different parameters such as leaching time, sulfuric acid concentration, ore ...
