Chemical Leaching. After air classification and potentially additional grinding, a fraction of the wood chips are leached. Leaching experiments using loblolly logging residue wood chips have been conducted at various levels of sulfuric acid concentration, temperatures, and leaching times (Idaho National Laboratory, unpublished results).

This process uses aqueous (waterbased) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leaching is the process of using percolating chemical solutions to leach out metals. Heap leaching is very commonly used for lowgrade ore, which would otherwise not be economical to send through a .

The chemical reduction of pure molybdenum trioxide or ammonium dimolybdate to metal requires two stages because conversion directly to metal releases heat that inhibits the process. The first stage reduction to MoO 2 is performed in the 450650°C range. Molybdenum dioxide is then reduced to molybdenum metal in second stage reduction, using temperatures in the 1,0001,100°C range.

4. Leaching. The deslimed solids are subjected to an upflow of leach solution. The upflow of solution causes expansion of the solids bed to allow a 'fluidised bed' to form in the reactor. Leach times required are site specific, but generally high leach recoveries can be achieved in less than 8 hours.
