solutions that give a metallurgical result that is economical and can be realistically implemented.” Process solution testing is completed either at a customer’s site or at Nasaco’s South African laboratory, which boasts three Automated SEM units from the Field Electron and Ion Company to complete mineral liberation analysis.


In addition to precise mineralogy, engineers have expertise and experience in prescribing chemical and reagent formulation and blends. As a result, they can collaborate with an operation to design and provide custom formulations and blends of specifi c products tailored to a plant’s applications. Mineral processing

plants benefi t from the continuous support of through Operational Mineralogy services. “T e most obvious gains are in the metallurgical performance, improved recovery, improved quality of concentrate, and reduction of undesirable species, whether they are trace elements or gangue minerals,” Isherwood further clarifi es. However, the benefi ts are not just about improving concentrate composition. Improvements provided by Operational Mineralogy impact an entire mineral processing operation. Isherwood adds, “Changing or modifying a collector and frother suites often improves recovery, but is also reduces pH, uses a less hazardous product, reduces the amount of gangue fl oated and enhances the selectivity of the actual collector and frother suite by using a co-depressant.”
