Jan 07 2019· One of the most popular and economical methods of controlling algae is a chemical product called copper sulfate It s also effective at treating areas for the organisms responsible swimmers itch as well as parasites like leeches and ich Copper sulfate contains copper as well as sulfur and is available in crystal or granular liquid and powder form
Stage 3 Roasting At this stage of the process the chemical reactions begin They convert the copper minerals into copper metal We can illustrate the types of process using the example of chalcopyrite CuFeS 2 From the formula it is clear that iron and sulfur have to be removed in order to produce copper
Aluminum or aluminium Al is a silvery white metal with a melting point of 660 °C 1 220 °F and a density of 2 7 grams per cubic cm The most abundant metallic element it constitutes 8 1 percent of Earth s crust In nature it occurs chemically combined with oxygen and other elements In the pure state it is soft and ductile but it can be alloyed with many other elements to increase
iron copper II sulfate → iron II sulfate copper Fe s CuSO 4 aq → FeSO 4 aq Cu s Since iron is cheaper than copper the use of scrap iron is a cost-effective way to produce
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99 99 pure copper called cathodes which will ultimately be made into products for everyday use The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively …
To finalize the purification process chemical disinfection usually with chlorine or ozone or UV light is applied to the water to kill bacteria viruses and the hardy cysts produced by cryptosporidium and giardia Key Terms ozone A triatomic molecule consisting of three oxygen atoms It is an allotrope of oxygen that is much less stable
You may also come across it in other cases such as one method of extracting copper and in the purification of copper During electrolysis electrons are being added directly to the metal ions at the cathode the negative electrode The downside particularly in the aluminum case is the cost of the electricity
4b Purification of Copper by Electrolysis extraction from ore above The impure copper from a smelter is cast into a block to form the positive anode The cathode is made of previously purified copper These are dipped into an electrolyte of copper II sulphate solution When the d c electrical current is passed through the solution electrolysis takes place
• Copper is malleable ductile and an extremely good conductor of both heat and electricity • A computer contains around 1 5 kg of copper a typical home about 100 kg and a wind turbine 5 tonnes • Copper has low chemical reactivity In moist air it slowly forms a greenish surface film called patina this coating protects the metal from
If cost is a bigger concern than time or convenience the cheapest way to treat water is to leave it in a plastic bottle in the sunlight Leave clear bottles in the sun for a few hours and UV radiation and heat kills the microbes that cause diarrhea and other waterborne illness The Sodis for solar disinfection method was deployed in some
