Zarmehr Mining Industrial Group Knowledge-Based Company, with its specialized laboratory for analyzing gold and silver in ores, artifacts, and ingots, has succeeded in obtaining a laboratory accreditation license from the Standards Administration in 2009, as well as a license to use the standard incentive mark for gold ingot products in 2015. Given the great importance it places on quality control of results, this laboratory has implemented the process of controlling output data with methods such as using duplicate samples from the grinding phase, using duplicate samples from the powder phase, placing CRM, RM, Blank, Replicate, and Duplicate samples in each series of sample analysis, and also sending inter-laboratory samples. This company, with advanced and sensitive analytical devices such as ICP-OES, FAAS, GFAAS… and using world-class methods, is able to provide the following services: 1. Analysis of gold, silver, palladium and platinum by the Fire Ace method 2. Multi-element analysis by preparing the sample in four acids and measuring using the ICP-OES device 3. Analysis of precious metals in high-grade concentrates 4. Determination of the purity of gold ingots and artifacts 5. Determination of the purity of silver ingots 6. Determination of the amount of impurities in gold and silver ingots 7. Design and conduct tests for processing gold from various mineral ores and optimizing its conditions 8. Design and conduct tests related to the extraction of gold and silver from mineral concentrates and other sources 9. Analysis of base metals by the acid dissolution method and reading with atomic absorption 10. Determination of crane activity 11. Determination of the purity of sodium cyanide 12. Analysis of gold and silver in charged and uncharged carbons 13. Analysis of gold, silver and metals Base in cyanide solutions 14. Physical and chemical analyses of kaolin samples
