How do you extract copper from bideaching?
Copper can be extracted from bioleaching by using bacteria to oxidize the sulphide minerals in the ore, releasing copper ions. These ions can then be leached out using a dilute acid solution. The copper can be further concentrated and refined through processes such as solvent extraction and electroplating.
In which areas of Mexico is copper mined?
Copper mining in Mexico is predominantly concentrated in the states of Sonora, Zacatecas, and Chihuahua. These states have rich deposits of copper ores and are home to several large-scale copper mines.
How do copper and South American deserts relate?
At one time, there were several copper mining towns located in South American deserts. Now, the copper mines have been long exhausted.
Will copper chloride react with sulphuric acid?
Yes, copper chloride can react with sulfuric acid, particularly if the sulfuric acid is concentrated. The reaction typically produces copper sulfate, hydrochloric acid, and water. However, the specific products and extent of the reaction may depend on the concentration of the reactants and the conditions under which the reaction occurs.
What are some examples of concentrated solutions?
Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt
What acids affect copper the most?
You can dissolve copper in concentrated nitric acid.
What happens when copper is added to concentrated sulfuric acid and heated gently?
copper sulphate and hydrogen is released.
Why copper ore is not concentrated by hydraulic washing?
copper ore is usually in the form of malachite, needs to be refined through chemical method.
What are the reactions of copper and zinc metal using concentrated nitric acid concentrated sulfuric acid potassium chloride solution and zinc powder metal?
copper+nitric acid > copper nitrate+hydrogen copper+sulpuric acid> copper sulphate+ hydrogen copper+potassium chloride> copper chloride+ hydrogen copper+ zinc carbonate (powder metal) > copper+ zinc + water + carbon dioxide zinc+nitric acid > zinc nitrate+ hydrogen etc just replace the copper in the above equations with 'zinc' for all the zinc solutions x
Does phosphoric acid react with copper?
Yes, phosphoric acid can react with copper to form copper phosphate and hydrogen gas. This reaction can occur more readily in concentrated solutions of phosphoric acid.
HOW Copper metal reacts with hot concentrated sulfuric acid?
Copper does not react with hot concentrated sulfuric acid due to its passivating oxide layer that prevents further reaction. The reaction between copper and sulfuric acid mainly occurs with dilute sulfuric acid, producing copper(II) sulfate and sulfur dioxide gas.
What happens when copper turnings are boiled with concentrated nitric acid?
When copper turnings are boiled with concentrated nitric acid, the copper reacts with the nitric acid to form copper(II) nitrate, nitrogen dioxide gas, and water. The reaction is highly exothermic and can produce toxic nitrogen dioxide gas. This reaction is often used to clean copper surfaces.
What is used in phytomining to remove copper compounds?
Phytomining uses plants to absorb copper compounds from soil through their roots. Once the plants accumulate copper, they are harvested, dried, and burned to produce ash containing concentrated copper, which can then be extracted and purified for use.
Will any metal stand against sulfuric acid?
depends on the concentration. for example, dilute sulfuric acid does not react with copper, however when it is concentrated it will oxidize copper to copper sulfate being itself reduced to sulfur dioxide.
Why don't we make hydrogen when reacting an acid with copper?
Copper is unreactive and will not react with acids to liberate hydrogen gas. However it may react if concentrated and oxidising acids are used.
What is the balanced equation for the reaction of phosphorus with concentrated nitric acid?
Pieces of copper are added to hot concentrated solutions of hydrochloric, phosphoric, sulfuric and nitric acids. A reaction clearly takes place between copper and nitric acid. The presence of copper ions can be observed by adding each solution to a dilute solution of ammonia. If copper ions were present, we would see the blue color of the copper-ammonia complex. Sulfuric acid has oxidized the copper metal, as indicated by the blue color. Nitric acid is a stronger oxidizing agent (and produces a higher concentration of copper(II) ions), as indicated by the darker blue color.
Will sulfuric acid corrode copper?
Sorry, copper does not react with sulphuric acid because it is not reactive enough to do so. Only metals which are higher than hydrogen in the reactivity series will react with sulphuric acid.
