At present‚ the raw materials to refine copper in China mainly are towanite‚ chalcocite‚ bornite‚ malachite and etc. According to the technical conditions of smelting‚ the copper ore can be divided into three classes based on the proportion of copper oxide and copper sulphide‚ that is‚ sulfide ore‚ which contains less than 10% copper oxide；oxidized ore‚ which contains more than 30% copper oxide; mixed ore‚ which contains 10%~30% copper oxide. Copper is one of earliest metals that be found and used

Quantitative Analysis: % Copper in an Ore May 3‚ 2006 Abstract: In this experiment we were given an unknown sample of ore. Using the spectrophotometric analysis and the electrogravimetric analysis‚ we found the unknown percentage of copper in the unknown sample of ore was to be 17.6% by mass. Introduction: Chemical analysis takes place under two different scenarios. In one case‚ you need to find out the chemical identity of some material. The first kind of analysis‚ in which the chemical

Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6
