Review of uncertainty in the collection and interpretation of leaching data

摘要: Abstract The literature on the determination of mechanisms mineral leaching reactions is reviewed to identify sources uncertainty about conclusions drawn. Uncertainty mechanism a system arises in measurement, data processing and decision-making stages. There accuracy, validity adequacy collected. effects most more than 30 variables phenomena are seldom determined. less certainty tests model equations against rate commonly accepted. Approximate calculations absolute mass transport could be basis better test mechanism. direct basic premises subsidiary assumptions preferred mechanisms. References given illustrate good practices achievements reducing uncertainty.
