Key Terms
Fire Assay
A mineral assayer specializing in fire assay performs precise quantitative analysis of precious metals such as gold, silver, and platinum in ore samples. This process involves melting samples with fluxes to separate valuable metals from impurities, providing accurate measurements critical for mining and refining industries. Mastery of fire assay techniques ensures reliable valuation and quality control of mineral resources.
Gravimetric Analysis
Mineral assayers specializing in gravimetric analysis measure the quantity of specific minerals by isolating and weighing precipitates from ore samples. This precise method involves chemical treatment to convert minerals into weighable forms, ensuring accurate determination of metal content such as gold, silver, and lead. Expertise in gravimetric techniques is essential for validating ore grades and supporting mining operations with reliable assay results.
Atomic Absorption Spectroscopy (AAS)
A Mineral Assayer specializing in Atomic Absorption Spectroscopy (AAS) performs precise quantitative analysis of metal concentrations in ore, minerals, and soil samples. Utilizing AAS technology, they detect trace elements such as lead, copper, and zinc by measuring light absorption at specific wavelengths, ensuring accurate compositional data for mining and metallurgical processes. Proficiency in sample preparation, instrument calibration, and data interpretation is essential to deliver reliable and reproducible assay results critical for resource evaluation and quality control.
