Can you use peroxide after extraction?
Hydrogen peroxide can be used after an extraction but it may irritate the skin. Estheticians recommend using a mild toner instead.
Which of these is a disadvantage of using natural gas?
Extraction through fracking can contaminate groundwater
What is a problem with using iron straight from a blast furnace?
That iron is too brittle.
Why the empirical formula of copper oxide cannot be determine by using the same technique as magnesium oxide?
Because Copper is a transition metal with variable velancies. Either +2 or +3 so unless the velancy is given you can't use the easy way out:)
What are the three stages in which copper is extracted from copper sulphate?
The first step is extracting copper from its ore, including the sulphate, to remove waste constituents like limestone and silica so that the copper and other minerals of value are concentrated into a product containing between 20 and 30 percent copper. The second step is to smelt (blast furnace with coal) or leach (reacting with an acid then using electrolysis) the product which also removes a large amount of impurity elements like iron and for sulphide ores, sulfur. The final step, refining, removes the last traces of the impurity elements and produces a copper product of 99.99 percent purity.
Is hydrometallurgy used in mining copper?
Hydrometallurgy is used for the processing of copper.Example: Leaching of copper oxide ores using a solution containing sulphuric acid. The Copper can then be recovered from solution using solvent extraction and electrowinning.
Can all copper be refined using the solvent extraction-electrowinning method?
It is estimated that only 15 percent of world copper reserves and 13 percent of U.S. copper reserves can be processed via the SX-EW method.
What is hydrometallurgy?
The use of aqueous solutions for the recovery of metals. Example: Leaching of copper oxide ores using a sulphuric acid solutions (or solution containing sulphuric acid). The Copper can then be recovered from solution using solvent extraction and electrowinning.
What name is given to the method of extracting copper from an ore using electricity?
This process is called "electrowinning" of copper.
How do you purify copper sulphate?
By the method of electrolysisCopper is a good conductor of electricity, and is used extensively to make electrical wiring and components. The extraction of copper from copper ore is done by reduction with carbon, but the copper produced is not pure enough for use as a conductor, so it is purefied using electrolysis.
What name is given when extracting copper from an ore using plants?
Phitomining (probably spelt wrong)
What is sentence using the word furnace?
a furnace is hot thats all i know
Why does a potato acquire a greenish deposit at the anode during electrolysis of potato?
You do not mention what you are using as the anode and cathode, but i would assume that given the green colour you are using copper or brass perhaps as the anode, and it is breaking down into a copper carbonate(which is green). By applying electrical current to the circuit you are speeding up the conversion of copper to copper carbonate(or similar).
What are the benefits of using a home furnace?
There are a number of potential benefits in using a home furnace. A natural gas burning furnace produces lower emissions than other forms of heating. It is said that homes heated through a furnace feel warmer than other methods.
How much copper is extracted from smelting?
Copper Smelting Process:First the ore is enriched by a process called flotation. Powdered ore is mixed water as a slurry and then further mixed with oil and a chemical called amyl xanthate. Compressed air is then blown through the mixture. The flotation process is dependent on pine oil droplets (Pine oil is just an example.) The less dense copper sulphide particles are carried to the top and are skimmed off.The next step carried out in an oxygen flash furnace is heated using natural gas to a high temperature. Next added is limestone and sand, and fresh copper ore concentrate is blown into the furnace with oxygen. It is heated and the combustion with oxygen is endothermic.The silicone dioxide in the sand reacts with the limestone and part of the ore (often iron oxide) to form slag. At the same time another element (often sulphur) melts and flows out of the bottom of the furnace. The slag is less dense and floats on the top.The copper matte,(product of the previous step) is run into a converter furnace, where air containing oxygen is blown through the copper matte to oxidize the ions. At the same time some of the ions reduce the copper ions to impure blister copper metal. A final heating in an anode furnace is used to burn off the remaining oxygen.The final step is the conversion of the impure copper to pure copper. This is done by electrolysis where the impure copper is made into the anode electrode and the pure copper is formed at the cathode electrode.
What are the risks of using a gas furnace?
The most important risk in using a gas furnace is carbon monoxide. If the heat exchanger in a gas furnace is damaged, carbon monoxide could leak into the air, causing a health hazard. A carbon monoxide detector and regular inspections would greatly reduce the risks and your worries in using a gas furnace.
DNA extraction from bacteria?
DNA extraction from bacteria can be achieved in various ways. Yeast is the best resource to extract the DNA bacteria from using extreme rapid extraction method.
