FAQs

Metallurgical laboratory quality assurance audits should be conducted at least annually for internal reviews, with more comprehensive external audits performed every 2-3 years. Additional audits may be necessary when implementing new testing procedures or equipment, or when preparing for critical project milestones.

This checklist covers sample receipt and preparation protocols, testing equipment calibration and maintenance, standard operating procedures for various tests, quality control measures, data recording and management systems, staff qualifications and training, laboratory safety practices, and reporting procedures.

The audit should be led by a senior metallurgist or quality assurance specialist with extensive experience in metallurgical testing. The audit team should include laboratory managers, key technical staff, and potentially external consultants for an impartial assessment. Participation from project geologists and process engineers can also provide valuable input.

The checklist includes items to evaluate sample chain of custody procedures, storage conditions, subsampling practices, and contamination prevention measures. It also assesses the laboratory's protocols for handling different types of ore samples and ensuring representative testing across various ore types and grades.

Yes, this checklist is designed to be applicable to both in-house mine site laboratories and independent commercial metallurgical testing facilities. However, it may need to be customized to address specific requirements of different laboratory setups, such as ISO accreditation for commercial labs or integration with mine operations for in-house facilities.
