Big tanks may be filled with pieces of ore like a laboratory percolator and then the ore may be percolated. Such an pilot plant has been set up at the John D. Sullivan Centre for InSitu Mining Research in Socorro, New Mexico. The advantage of such a tank leaching is that the process can be easily controlled and regulated.

Laboratory tests Before laboratory leaching tests, the stakes were cut into two 25 cm long specimens to give parts for discontinuous and continuous water immersion. Two modified laboratory tests were employed to perform leaching on the treated stakes. These half stakes refer to EN 252 stakes exposed in UC3 and UC4 situations.

laboratory with equipment and reagents that are readily available and can be taken to the field in the back of a vehicle (fig. 4). Onsite leaching requires only the return of the preserved filtrate to the laboratory for analyses. In contrast, the EPA (SPLP) procedure requires specific, costly equipment and must be performed in the laboratory.
