38. For efficient recovery of mercury the following techniques can be used: – Measures to reduce dust generation during mining and stockpiling, including minimizing the size of stockpiles; – Indirect heating of the furnace; – Keeping the ore as dry as possible; – Bringing the gas temperature entering the condenser to only 10 to 20 °C above the dew point; – Keeping the outlet temperature as low as possible; and – Passing reaction gases through a post-condensation scrubber and/or a selenium filter. Dust formation can be kept down by indirect heating, separate processing of fine grain classes of ore, and control of ore water content. Dust should be removed from the hot reaction gas before it enters the mercury condensation unit with cyclones and/or electrostatic precipitators.
