Abstract
In this thesis,a series of oxidation experiments on galena are conducted under different condition such as pH is 2,temperature is 50°C and 25°C.After the experiment is completed,The rate constant,reaction order，reaction reaction rate and energy of activation are also analyzed and computed.The effects of temperature and oxidized medium on lead ore oxidation speed were studied. Under the condition of 50°C, The rate of oxidation reaction is increase when concentration is 100mg/l.The higher the concentration the more sulfuric acid ion,the easier to produce sediment of lead sulfate , so the reaction will be impeded .the reaction will be extremely slow or even can’t carry on at 25°C.
