Our team in Iran is working on processing of gold, lead, zinc, lithium, rubidium, rare earth elements ores. Despite the success in conducting some processing methods, the lack of access to modern technologies such as QEMScan has made it difficult for us to analyze the results and optimize the processing methods. For example, after the concentration of gold-bearing pyrite with a recovery of about 70%, the gold in the tailings should be analyzed in a suitable way to determine the distribution of gold in the tailings. Is there a laboratory or a team ready to cooperate in this field? collaboration may be in exchange for services and payment of fees or in the form of joint research work. Our team is ready for both options.
