Liquid deposition techniques engineering

Many of the procedures applied in this field are modifications of chemical engineering techniques, mainly in the area of solid-solid or solid-liquid separation. The more advanced techniques are washing procedures, of which the fine-grained residues are eventually deposited. With respect to acid extraction procedures, there are many experimental designs, but few practical applications. Electrochemical procedures are in progress, in particular for in-situ-reclamation of metal-rich areas.
