Analyses of rare earth elements (REE) in gold-bearing quartz vein, granite and altered wall-rock (amphibolite) collected from Jiapigou gold belt in Southeast Jilin Province were conducted using inductively coupled plasma-mass-spectrometry (ICP-MS). The results indicated that the Jiapigou gold belt underwent two periods of gold mineralization: the earlier mineralization was related to the intrusion...
Effects of flaky rare earth oxide additives including Er 2 O 3 , Tm 2 O 3 , and Yb 2 O 3 , Lu 2 O 3 on high temperature and high rate discharge performance of nickel electrodes were investigated. The discharge efficiency at 0.2C reached 96% at 60 °C for electrodes with 1 at.% flaky rare earth oxides. The high rate discharge performance...
