At Iluka Resources, we rely on reference materials for quality control monitoring of our laboratory processes during mineral sands exploration and processing. We first contacted Independent Mineral Standards (IMS) to prepare a batch of mineral sands reference materials. After evaluating the homogeneity of the batch provided by IMS, it became apparent that batches from our previous supplier required reprocessing. IMS has since reprocessed three batches of reference material for us, resulting in a significant decrease in typical relative standard deviation from 4.5% to 0.9%. By switching to IMS as our supplier, we have greatly improved our process control and quality control through the use of fit-for-purpose reference materials.

IMS helped us define the scope and technical parameters for a projects to make reference materials to address a series of complex technical QC challenges. The end product had targeted particle size distribution (PSD) materials to match our process. IMS also developed pigeon-pair CRM materials for monitoring both production process and geological sampling. These materials fitted in the QC of on-site grade and process control analysis.

The initial engagement with IMS involved in-depth discussions and collaboration around the finer technical details of QC monitoring, with the aim of aligning their CRM products/certificates to our meet our operational requirements. This included new, larger 7.2t batch sizes that could be shared across multiple sites, and pulp CRMs that had closer element rates to the products being analysed by the labs.
Having worked with IM now for several years, this initial collaboration led to great results and a trusted on going relationship.
