Arsenic Mining Processing

Known as process water ponds the basins allow muds that are washed from grains of frac sand to settle from water that is reused in the process A letter from DNR Nonmetallic Mining coordinator Roberta Walls to Chippewa County Director of Conservation Dan Masterpole said mud samples from the ponds exceeded state safety levels for arsenic a.
