Development of a Computerized Automated Rapid Weathering Apparatus for Determining Total Lime Requirements for Acid Minesoils

Abstract

dicting lime requirements are inadequate for evaluating ongoing acid production from acid rninesoils. The primary objective of this study was to develop a computerized automated rapid weathering apparatus (CARWA) that could determine. total, one-time application lime requirements for acid minesoils in a 24 hour time frame. Comparisons of CARWA lime recommendations to those determined by the laborious, time consuming manual laboratory weathering method indicate that rapid weathering is feasible.
