:: WorstPolluted : Projects Reports
Mining and Ore Processing Mercury Pollution. Estimated Population at Risk: 1.5 Million. Description. Mining and ore processing occurs throughout the world and consists of extracting minerals, metals, and gems from surrounding earth and ore. Industrial mines vary in size, with some being quite small operations and others very large.
The effect of pH value on gold extraction for various ore types is shown in Figure 28.4. Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes ∼pH 9.5–10.0, whereas for some carbonaceous ores, pH value has no apparent effect.
