Geochemical characteristics of ores and surface waters for environmental risk assessment in the Pinpet iron deposit, southern Shan State, Myanmar

Resource Geology, Volume 70, Issue 3, Page 296-308, July 2020., 2020
Geochemical results indicate no significant contamination occurred in the surface water due to the mining activity and beneficiation process of hematite and limonite ores in Pipet iron deposit, Myanmar. Bulk mineralogical and chemical analyses of ore samples demonstrated that some limonite ore samples contain significant amounts of Arsenic (up to 2 wt%)
