【SMM Nickel Market Flash】A recent study published in the journal Inorganic Chemistry has introduced an innovative and efficient method for extracting valuable metals from low-grade nickel sulfide ores. The process involves preroasting the ore followed by chlorination roasting using ferric chloride hexahydrate (FeCl3·6H2O). Researchers achieved high extraction rates of 95.5% for nickel, 94.4% for copper, and 92.1% for cobalt under optimized conditions. The study provides a significant theoretical foundation for advancing this new roasting technology, offering a promising new route for processing low-grade nickel resources.
