containing copper compounds (such as copper carbonate) are called ‘copper ore’. Copper is extracted from copper ore by a series of chemical‚ physical‚ and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining‚ the ore is crushed‚ roasted‚ smelted and then electrolysed to extract the copper. Suggested Equipment Boiling tube Samples of different carbonate ores‚ containing

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

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around

Accounting and Quantitative Analysis Report Project Appraisal- Net Present Value and Internal Rate of Return Driss Fares-Introduction In this report‚ I aim to present a thorough outline of a method of project appraisal: Net Present Value (NPV). This is a dynamic investment appraisal that utilizes a discounted cash flow method. Along with the IRR (internal Rate of Return)‚ the NPV method is regarded as more comprehensive than the simpler‚ more traditional Payback method. It withal
