does copper react with sulfuric acid ? | Yahoo Answers
Copper Oxide is a BASE and reacts with Sulphuric acid to form a Salt + water. "Lower purity scrap is usually refined to attain the desired purity level by an electroplating process in which the copper scrap is dissolved into a bath of sulfuric acid and then electroplated out of the solution."
12.3 Primary Copper Smelting
sulfuric acid plant to treat copper smelter effluent gas streams requires that particulate-free gas containing minimum SO2 concentrations, usually of at least 3 percent SO2, be maintained. Table 12.3- 1 shows typical average SO2 ...
purification of copper by electrolysis metal extraction
The ash is dissolved in hydrochloric acid or sulfuric acid and the copper can be extracted by electrolysis or more cheaply by displacement of the copper with scrap iron. e.g. iron + copper(II) sulfate ==> iron(II) sulfate + copper. Fe(s) + CuSO 4 (aq) ===> FeSO 4 (aq) + Cu(s)
Impacts of copper mining on people and nature | Danwatch
The mining industry uses sulphuric acid in the extraction and treatment of copper. The extraction processes are called heap and situ leaching; during these processes, particles react with each other to create acidic mists that not only harm people’s skin, eyes and lungs, but also destroy crops, deteriorate the quality of the land, and damage ...

Effect of Copper Sulfate and Sulfuric Acid on Blind Hole Filling
Here, in a certain high density interconnect (HDI) printed circuit board, the effect of copper sulfate and sulfuric acid on the filling effect of a blind hole with a certain diameter and depth was investigated by making a blind hole using a CO 2 laser drilling machine, filling the blind hole via electroplating by simulating the electroplating line in a Halin cell, and observing the cross ...
Effects of pH and Temperature on the Leaching Reaction of
The copper extraction of chalcopyrite attained 94% after 11 days when the initial pH value was 0.7 and the extraction temperature was 60 centigrade, while it was under 5% at pH 2.0. If the temperature was over 40 centigrade

Extraction of Copper from Sulfate-Chloride Solutions by... | SpringerLink
Copper extraction isotherms were determined at 25 and 35 °C for aqueous solutions containing 6 g/l of Cu, 7 g/l of Fe, chloride ion concentrations of 0, 60 and 110 g/l, and a pH of 2.0. The organic phases were 20% v/v solutions of a ketoxime (LIX 84-IC) or a salicylaldoxime (LIX 860 N-IC) .
Sulfuric Acid Leaching of Smelter Matte
Sulfuric acid leaching of lead smelter mattes resulted in the recovery of about 45 pct of the nickel and cobalt and 10 to 45 pct of the copper. The cobalt and nickel extractions were found to be less dependent on the concentration of sulfuric acid and manganese dioxide than the copper extraction.
Copper Production: How Is Copper Made? - ThoughtCo
Sep 26, 2019 · The development of SX-EW has allowed copper extraction in areas where sulfuric acid is not available or cannot be produced from sulfur within the copper ore body, as well as from old sulfide minerals that have been oxidized by exposure to air or bacterial leaching and other waste materials that would have previously been disposed of unprocessed.
Innovations in Copper: Mining & Extraction: Producing copper
Prior to the development of the solvent extraction-electrowinning (SX/EW) process in 1959 (see Copper the Green Metal), the only way to recover copper from an acid solution was by a process called cementation. In this process
