Such minerals may contain high concentrations of lead, zinc, and copper, usually in sulfide minerals like galena (lead sulfide), sphalerite (zinc sulfide), and chalcopyrite (copper iron sulfide). Since they are included within the sedimentary strata they are called stratabound mineral deposits.
Near smelters that process copper ore into metal, concentrations may reach 5000 ng/m3. You may breathe high levels of copper containing dust if you live or work near copper mines or processing facilities.
Student Handout Spectrophotometric Determination of Cu2+ The Problem Branicoda Copper Mine is considering opening up a new mining site. The geologists feel that there are copper rich ore bodies present at this new site. Samples of these ores were sent to Water Wagon Laboratories to be tested. The ore samples were recently leached with sulfuric acid to bring Cu2+ (copper
Full Answer. Copper appears most frequently in deposits in which lead, silver, gold and zinc are also present. Porphyry copper deposits contain the most significant finds of copper; porphyry deposits began as large concentrations of molten rock that slowly cooled, crystallizing inside Earth's crust.
