39 <br />water table and are extracting ore from disseminated deposits. <br />In these cases it should be realized that mine effluents <br />will be more susceptible to turning into pollution problems. <br />SUMMARY <br />Two requirements are needed for a chemical reaction <br />to proceed. The necessary reactants have to be available, <br />and the encounter of these reactants to make the product <br />has to be reasonably rapid. The ore petrology, ground water <br />hydrology and ore occurrence are factors which do not change <br />the weathering reactions. Instead these parameters can <br />change so that the reactions won't proceed. In some in- <br />stances, a reactant is not available such as when ground <br />wafer cuts off the air sup-ply. In other instances the speed <br />• of the reaction is slowed such as when large crystals <br />in a vein are weathered as opposed to smaller crystals dis- <br />seminated uniformly through a deposit. Obviously, it would <br />be reasonable to design mine effluent operations so that <br />the factors which diminish the weathering of pyrite are <br />functioning. <br />•
