Concentration Of Gold Ores A Key To Reducing Mercury Use

Jun 03, 2012 As an important first step along the way to eliminating mercury, concentrating avoids a worst practice called whole-ore-amalgamation, where mercury is brought into contact with 100% or the ore and losses of mercury to the environment can be very high as high as 50 parts mercury for every part gold produced (more often ranging from 201 to 41). Simple concentration methods reduce the amount of
