Secondary sulfides those formed by supergene secondary enrichment are resistant (refractory) to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits. Supergene ores rich in sulfides may be concentrated using froth flotation. A typical concentrate of chalc
Hydrochloric and phosphoric acid don't oxidize metals well and won't dissolve copper. Sulfuric acid has a medium oxidizing ability and will dissolve copper over time. With a high oxidative strength, nitric acid will completely dissolve copper, turning it green and then
the reaction between sulphuric acid and copper oxide creates copper sulfate which has a blue color and blue copper sulfate pentahydrate crystals can be created.
Place some sulfuric acid in a conical flask and warm it in a water bath. Add a spatula of copper oxide powder to the acid and stir with a glass rod. Continue adding copper oxide powder until it is
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
Reacting Copper Oxide with Sulphuric Acid. Mixing copper oxide and sulphuric acid is an experiment involving an insoluble metal oxide which is reacted with a dilute acid to form a soluble salt.Copper (II) oxide, is a black solid, which, when reacted with sulphuric acid creates a cyan-blue coloured chemical called copper II sulfate. Copper (II) oxide reacts with sulfuric acid to

Copper oxidation in 1–10 M sulfuric acid solutions is studied using cyclic voltammetry and x-ray diffraction methods. Copper passivation is shown to be caused by the formation of a resistive
2. copper(II) oxide + sulfuric acid → copper(II) sulphate + water CuO(s) + H 2 SO 4 (aq) → CuSO 4 (aq) + H 2 (l) 3. It indicates that the copper oxide was present in excess. This makes sure that all the acid is reacted. This is important because we will be heating the solution after filtration and hot, concentrated acid would be dangerous.
Hydrochloric and phosphoric acid don't oxidize metals well and won't dissolve copper. Sulfuric acid has a medium oxidizing ability and will dissolve copper over time. With a high oxidative strength, nitric acid will completely dissolve copper, turning it green and then blue as the metal wears away in a matter of minutes.
The Democratic Republic of Congo copper oxide ore containing mainly malachite was leached in sulphuric acid. The effects of leaching time, pH, stirring speed, and
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)
place some sulfuric acid in a beaker and warm it in a water bath add a spatula of copper(II) oxide powder to the acid and stir with a glass rod continue adding copper(II) oxide
The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. A by-product of the smelting and converting furnaces is sulfuric acid. In what looks like a lucky coincidence, sulfuric acid is needed
Ores containing cupric oxide, CuO, are commonly reacted with sulfuric acid to produce a copper containing material that is more easily processed. This process is known as sulfuric acid leaching. Write a balanced chemical equation for the reaction of cupric oxide with sulfuric acid. Cupric oxide is another name for copper(II) oxide.
The reaction between copper oxide and sulphuric acid
For example, the blue copper salt copper(II) sulfate, commonly used for electroplating and as a fungicide, is prepared by the reaction of copper(II) oxide with sulfuric acid: CuO (s) + H 2 SO 4 (aq) → CuSO 4 (aq) + H 2 O (l) Sulfuric acid can also be used to

This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. A by-product of the smelting and converting furnaces is sulfuric acid. In what looks like a lucky coincidence, sulfuric acid is needed to treat oxide ores in processes called leaching and SX-EW
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
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper(I) oxide (cuprous oxide). As a mineral, it is known as tenorite.It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds.

They show you how to make copper sulfate from copper and sulfuric acid using two chemical methods and one electrochemical method. Copper does not directly react with sulfuric acid so some form of oxidant is needed. Hydrogen peroxide and nitric acid are excellent oxidants and the first two methods demonstrate this.
