Como Engineers was engaged to supply a 5T Modular PLC Automated Pressure Zadra Elution System with a 250kg/hr LPG fired kiln supplied by its long-term partner Custom Furnaces, including the carbon regeneration structure, feed hopper, quench tank and ancillary equipment. The scope also included the design of the modular gold room, with the supply of the smelting furnace, safe, drying oven and other gold room equipment. The elution plant was designed, fabricated, assembled and hot run tested in Perth prior to disassembly, packing and delivery by truck to site, while the Carbon Regeneration Kiln, hoppers and chutes were fabricated in South Africa and shipped to site. The elution system included a 1200kW Direct Eluate LPG fired Heating system with full PLC control of all elution and electrowinning process steps, and a closed loop cooling system, among other adaptations, was introduced to reduce the client’s water usage.
