The copper was found to be cuprous oxide (Cu 2O) and ele-mental copper (Cu0) in the preliminary study. Only a few studies examined the leaching of cuprite (Cu 2O)7–10). In these studies, leaching tests were carried out using various solutions, such as sulfuric acid with ferric sul-fate7 ), sulfuric acid with perchloric acid8,9, and sulfuric acid
Acid = Dilute Sulfuric Acid Insoluble Base = Copper (II) Oxide Method: Add dilute sulfuric acid into a beaker and heat using a bunsen burner flame; Add copper (II) oxide (insoluble base), a little at a time to the warm dilute sulfuric acid and stir until the copper (II) oxide is in excess (stops disappearing)
I assume you mean copper(II) oxide, which is black, and not copper(I) oxide which is orangey-red.copper oxide + sulfuric acid --> copper sulfate + water. How do you make copper sulphate?
Commonly sulfuric acid is used as a leachant for copper oxide, although it is possible to use water, particularly for ores rich in ultra-soluble sulfate minerals. [ citation needed ] In general, froth flotation is not used to concentrate copper oxide ores, as oxide minerals are not responsive to the froth flotation chemicals or process (i.e.; they do not bind to the kerosene-based chemicals).
10-12-2019· To make copper sulfate in a science lab, start by pouring sulfuric acid into a glass beaker and heating it until it's almost boiling. Then, carefully add small pieces of copper oxide to the hot solution, stirring the mixture lightly for 30 seconds after each addition.

Sulfuric acid (American spelling) or sulphuric acid (British spelling), also known as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H 2 SO 4.It is a colourless, odourless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic.
These copper oxide ores are usually leached using sulfuric acid to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate solution.
