copper solvent extraction process

The adaptation of thesolventextractionprocessto the metallurgical industry has been extremely slow up until recent years. In fact, the complexity and multiplicity of choices facing the extractive metallurgist are almost bewildering and sometimes it is difficult to know how to start the development...
