Hydrometallurgy of CopperS. K. Young Minerals, Metals, and Materials Society, 1999 - 626 sayfa The hydrometallurgical papers of Volume IV highlight optimization efforts in solvent extraction/electrowinning operations in North and South America. Biohydrometallurgy, for example, not only takes a key role in copper recovery in many leach operations but offers a new role in cost-effective environmental remediation. The discussions of several approaches to the treatment of copper sulfide concentrates emphasize the high level of interest in finding alternative means of recovering copper and precious metals and avoiding many of the costs and impurity issues associated with the conventional processing. |
