These mines have now closed and today the biggest copper mines are in Chile (ndida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper
Contact Us2013128ensp;0183;ensp;I'm struggling to even attempt to begin solving this question. A sample of ore from a copper mine contains a mixture of copper sulfate, copper sulfide and copper oxide. A finely ground sample of this material (10.32g) was treated with sulfuric acid to dissolve all of the copper compounds. The resulting sample was filtered to remove undissolved material.

Contact UsIntroduction Electrogravimetric and spectrophotometric analyses of unknown copper ore sample were completed to determine the percentage composition of copper in the sample. Electrogravimetric analysis proceeds by putting the copper from the sample into solution, then plating the copper on to an electrode to determine the change in mass. Gravimetric analysis is an important part of analytical
Contact UsThe process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first
