Bayan Khundii Gold Project – 3t Modular Pressure Zadra Elution Plant

Como Engineers was awarded the supply contract by Erdene Resource Development Corporation for a gold elution plant for the Bayan Khundii Gold Project, located in Bayankhongor Province, Mongolia. Como Engineers worked closely with Erdene to provide a tailored three tonne Pressure Zadra Gold Elution Plant, complete with regeneration kiln and gold room, to fit within the confines of a dedicated enclosed building for the 1,800 tonnes per day CIP gold process plant. Bayan Khundii is located three hours drive from the nearest town and experiences temperatures ranging from below -35°C in winter to +35°C in summer. The ease of transport, erection on site and commissioning provided by the modular design were key factors in the successful bid. Como Engineers supported Erdene in the development of the Bayan Khundii operation, which poured its first gold in September 2025.
