Relationships Between Conductivity and pH in Channels Exposed to Acid Mine Drainage Processes: Study of a Large Mass of Data Using Classical Statistics

摘要

The lack of statistical interdependence relationships between pH and conductivity in channels exposed to Acid Mine Drainage processes is a phenomenon reported by various authors. Based on the study of a large mass of data with over 23,000 records of pH and conductivity taken in a typical mining channel in the Iberian Pyrite Belt in SW Spain, the present work confirms the existence of a quite different fact, which is the appearance of high negative correlation coefficients between both variables.
