Get Price2 a copper smelter slag from lubumbashi, democratic republic of congo, containing 1.4 cu, 0.7 co, 8.9 zn and 20.9 feii, has been used in this study.The leaching tests have been carried out at normal pressure on ground slag samples the dissolved base metals were successfully extracted from solution by solvent extraction using kerosene.
What Can I Do For You?
Solvent extraction.Once pls is leached, it is sent to a solvent extraction plant to remove the copper.The pls is mixed with an organic solvent that binds to the copper and chemically separates the copper from the rest of the liquid.Then, the copper-bearing liquid is combined with another acid to precipitate the copper from the organic material.
