Copper is an element that occurs in minor amounts in the earth’s crust. Estimates of average crustal prevalence are on the order of 0.0058 percent by weight. Deposits considered to be economically recoverable at current market prices may contain as little as 0.5 percent of copper or less‚ depending on the mining method‚ total reserves‚ and the geologic setting of the deposit. Here is the flow sheet on how to process copper from Zenith. Copper Process Flow Sheet: Copper ore is first quarried from

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
