The Integrated Organic Leaching - Solvent Extraction Operation in Hydrometallurgy,urden from the cost of the alkali, the addition of extra chemicals to a process system will at a later stage in the process have to be removed or reclaimed. Besides, the added chemicals will often end up as an environmental deposit problem.
