Mercury ore re-election
After the ore is rod milled to -2~-3mm, it is sent directly to the shaker for rough selection. The rough sand obtained by rough selection is sent to the shaker for cinnabar product selection. The cinnabar foot of the selected shaker can be floated. concentrate combined mercury into the furnace to produce metallic mercury, and reselected after milling tailings are sent to flotation, the concentrate smelting furnace mercury selected. The yield of cinnabar in re-election operation fluctuated by 20%~60% according to the metal mercury in the ore, the total recovery of re-election flotation was 95%, and the discarded tailings contained less than 0.01% of mercury. When the ore contains high levels of natural mercury, it can be treated with a natural mercury trap (below) before or during flotation to recover part of the natural mercury.
Natural mercury trap
Socket weld flange is flange type of ANSI B16.5 norm have class rating 150 300 600 900 1500 2500 facing type raised face RF and ring type joint RTJ, flange size NPS 1/2"-24", steel ASTM A105 A350LF A181 GR60 and more, socket welding flanges are similar to slip on hubbed flanges but difference for the flange center hole, there is a step in the flange center hole for socket weld flange.
