Coursework 4 Copper Name of student: Alfiya Ospanova Tutorial group: G Copper is one of the earliest elements explored by humanity. Due to the special red shade it was easy to find in ancient times. The metal was named according to place where it was found‚ the Cyprus islands. Copper produced in massive stars and spread in the world as minerals like chalcocite and chalcopyrite (sulfide of copper)‚ azurite and malachite (carbonate of copper)‚ cuprite (oxide of copper).

Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron

Copper Mining in Zambia Norman Mulimbwa Shachile WHUT‚ Luoshi Rd.‚ International students building No.8‚ Wuhan‚ 430070‚ PR China Abstract The mining industry has been the economic and social backbone in Zambia since the first major phase of exploitation of the Copperbelt ’s Cu-CO deposits commenced in the early 1930 ’s. Since that time a wide spectrum of other metalliferous and non-metalliferous resources have been discovered in Zambia and although exploitation of these has been limited‚ they

A REVIEW PAPER ON MINE FIRE IN INDIA INTRODUCTION The problem of mine fire is as old as the history of the mine. The fires in coal mines are posing great hazard due to its increasing trend in the world and much more so in our country while mining of thick and thin seams under difficult geo-mining conditions. Due to fires in underground as well as surface mines‚ not only a considerable amount of resources is lost‚ but the entire mine environment is badly affected. So long as the fires are restricted
