· Blasting of the second area should shake up the first area and restimulate copper production. One of the important obstacles to wider appliion of the in situ leaching method in copper mining is the uncertainty in predicting final recovery. To help resolve some of this uncertainty, the Bureau used data from the Sierrita and Emerald Isle experiments as input to a computer program which ...
