    This work in this thesis aimed to understand and characterize the elements of crud. Furthermore, to have an option to minimize crud formation in low-grade copper ore pregnant leach solution. The Solvent Extraction operations often suffer from increased purification complexity due to crud formation at the interface of aqueous and organic phases. Crud at the interface of SX generally comprises solid particles that are Al, Mg, Fe, and Si in the pregnant leach solution. Ion exchange resins have been using an option to increase the separation efficiency of the selected copper metal ions from the solution before the SX process. There is a fact, organic solvent consumption decreases by 63% and diluent by 86% after applying the Ion Exchange process in the Buchim copper plant. It directly reduces plant footprint and crud formation in the SX pond. Therefore, capital and operational expenditures on these factors are minimized.
