Abstract

These experiments were carried on in cooperation with I.I.R.S. and W.S.L. and were relative to a full scale in-situ leaching operation in the Avoca Mine (Ireland). The work to be done by B.R.G.M. in this study, was specifically the definition and running of a pilot column in which a sample of about ten tons of ore could be treated. The aim of this work was to examine the possibility to test the kinetics models of leaching to be developed by W.S.L. from experiment at laboratory scale on calibrated size fractions of ore. It was also intended to examine what information an experiment at this pilot scale is able to give, on what occurs during the large scale industrial heap leaching undertaken in Avoca Mine. In fact, the study of various phenomena occurring during heap leaching is difficult to perform on conventional heaps for many reasons: size of the heap; + non uniform flow of the leach solution through the heap; + poor precision in the position of the sensors and; + difficulty to obtain representative samples at different times.
