The largest single use of sulfuric acid is for the production of phosphoric acid, a precursor to phosphate fertilizers and non-fertilizer phosphates. All traded sulfuric acid comes practically from metals smelters (Europe is the biggest exporter), which produce sulfuric acid as a by-product which must be sent to market.
In light of the pH-dependent nature of the extraction process [11], the initial step involved the recovery of sulfuric acid to facilitate the adjustment of wastewater pH to suitable levels for copper extraction (pH ∼ 2.0 [11]).Both sulfuric acid and copper exhibit significant potential for reuse within the mining industry, thereby enhancing its overall …
Sulfuric acid is mainly produced from sulfur dioxide gas via a so-called contact process, where sulfur dioxide is made by burning of fossil fuels or it can exist as a by-product from zinc and copper smelting processes. ... sources, such as volcanic eruptions and rock weathering. However, emissions through anthropogenic sources, such as mining ...
Introduction. The conventional treatment of copper–gold concentrates involves smelting, converting and electro-refining to produce a copper-cathode product. Sulfur in the copper concentrates is oxidized to sulfur dioxide during smelting and converting and is normally used to make by-product sulfuric acid. Iron in the copper …
The owner of a copper mine in Antofagasta City, Chile wanted to replace its legacy centrifugal pumps used for injecting sulfuric acid into agglomeration tanks – where crushed copper is heaped into uniform …
complex commenced production of anode copper in February, 1966 and of sulfuric acid from converter waste gas in July of the same year. Palabora Mining Co. Ltd. is currently producing 80,000 tons per year of anode copper and 100,000 tons per year of sulfuric acid. A new 45,000 ton per year electrolytic copper refinery is presently being ...
What is Sulfide Mining? Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to ...
In the electrolytic process, copper anodes and starting sheets are immersed in an electrolytic solution made up of copper sulfate and sulfuric acid. An electric current is passed through the solution, and copper from the positively charged anode is deposited in a pure form on the negatively charged starting sheet, which acts as a cathode.
The on-site smelter is estimated to annually produce 300,000t of blister copper, along with 1,600t of sulphuric acid a day as a by-product. The sulphuric acid is proposed to be sold to copper-oxide mining …
