MATERIAL SELECTION & SHIPPING
Pilbara Standards' system is best suited for multiples of 3.6t batches for the most cost-effective production of coarse CRM. However, we can customise our process to suit client’s specific requirements.
Clients select and supply material for production of the reference material. Materials selected are usually based on a range of expected ore grades, or with expected deleterious analyte ranges. In addition, mine site specific waste rock is commonly selected for use as “blanks” to better mimic the “smearing” within sample preparation equipment. Material is shipped in 200 litre drums, or more commonly in bulka bags on pallets.


PRODUCTION PROCESS
The client is notified of sample receival with weights logged. Specific blending instructions are confirmed against the sample received. The material is then dried until constant mass, crushed and screened to client specified parameters (usually dried at 105 deg C, and maximum particle size between 2mm to 5mm). The material is then homogenised and divided via rotary sample dividers and bagged into 1kg to 4kg heat sealed plastic bags. All bags are given unique codes with sample division history recorded. The product is boxed and returned to client, less the samples taken for certification analysis.


CERTIFICATION PROCESS
Pilbara Standards manages the entire certification process, from random sample selection, laboratory selection (in conjunction with clients if required), analytical technique selection, sample submission, data compilation and verification, laboratory data analysis using appropriate ISO guidelines, and final certification.
