Affecting the Copper Mining Industry As is demonstrated by the chart below‚ the demand for copper has exceeded the supply brought to market since 2009. In 2011‚ 16.5 million tonnes of copper were produced worldwide and this amount is expected to grow by approximately 3% annually. Data from the International Copper Study Group (ICSG) for 2012 suggests that international demand for refined copper is expected to exceed production by about 240‚000 metric tons. The slow growth forecasted in copper supply is

Copper vs. fiber Everyone building a network must face this question at some point: fiber or copper wiring? For a usual home network or even a big office either one will suffice but what is the best option for you or your company. You have to take cost‚ distance of cabling‚ and bandwidth and speed into consideration when making this choice. Copper: a traditional copper wiring for a network certainly seems much cheaper on the surface. Copper wiring itself is dirt cheap at least comparatively

reactions. The firsts reaction involved adding hydrated copper (II) sulfate in water. The initial and final temperatures were recorded‚ and the ∆T of the trials were calculated. As the reaction was endothermic‚ which means it absorbs the heat‚ the temperature goes down and therefore the ∆T of the reaction is positive. The table below represents the information about the experiment: Data collection and processing of the dissolution of hydrated copper (II) sulfate ΔH/mol of the solution was calculated
