4. The electrolysis of copper(II) sulfate solution. The electrolyte copper(II) sulfate, provides a high concentration of copper(II) ions Cu 2+ and sulfate ions SO 4 2 to carry the current during the electrolysis process. There are tiny concentrations of hydrogen ions H + and hydroxide ions (OH ) from the selfionisation of water itself, but these can be ignored in this experiment.
Feb 14, 2006 · The Yulong copper belt is loed in the Qiangtang terrane of the Himalayan–Tibetan orogen (Fig. 1), on the north rim of the Himalayan ore zone in eastern Tibet (Yin and Harrison 2000; Sengor and Natalin 1996; Tang and Luo 1995).The Himalayan copper zone is closely associated with a belt of Cenozoic shoshonitic intrusions that are aligned along .
Samples of copper ore, such as malachite, could be shown, if available. For the second question, work out the concentration of copper in, say, test tube 3: Concentration Cu (as Cu 2+) = 4/10 x 1 M = M. Work out the concentration of copper ions when 5 g of copper carbonate is dissolved and made up to 100 cm 3 of solution (formula mass of ...
A good maximum sample size is usually around 10% of the population, as long as this does not exceed 1000. For example, in a population of 5000, 10% would be 500. In a population of 200,000, 10% would be 20,000. This exceeds 1000, so in this case the maximum would be 1000. Even in a population of 200,000, sampling 1000 people will normally give ...

Oct 26, 2009 · The theoretical graderecovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical graderecovery can be readily used to quickly identify .
In my sample playthrough, Copper sold at the Hive Settlement for 175 per ore (or higher), so at 300 a run I was making 52,500 per run. At the base price of 160, you''d be making 48,000 per run. 52,500 per run may sound like a lot but given the cost of particular research items, you can burn through it pretty quickly.
The process uses a lot of electrical energy. The copper ore is particularly difficult to mine. 8. ... Sample exam questions Edexcel.
The average massive sulphide camp in Canada has about 9 deposits, but ranges from four (Manitowadge) to 21 (Noranda), However, an individual deposit may consist of a number of closely associated, discrete lenses ranging from several thousand to several million tons in size (ea.
