After the leaching test, a solid fraction can be used to extract other metals or materials and then it has to be disposed of in landfills In a study developed by Muniyandi et al (2013) the non-metallic fraction was used as a filler material in recycled High-Density Polyethylene (HDPE), recycled high-density polyethylene (rHDPE) and in the production of rHDPE/PCBs composit.

Sulfuric acid leaching circuits commonly employ either manganese dioxide or chlorate ion to oxidize the tetravalent uranium ion (U 4+) to the hexavalent uranyl ion (UO 2 2+) Typically, about 5 kilograms (11 pounds) of manganese dioxide or 15 kilograms of sodium chlorate per.

Tank leaching is typically continuous, while vat leaching is operated in a batch fashion, this is not always the case, and commercial processes using continuous vat leaching have been tested; Typically the retention time required for vat leaching is more than that for tank leaching to achieve the same percentage of recovery of the valuable material being leached;.
