Guyan Gold Mine

Situated in the Najran region of southwest Saudi Arabia, the Guyan Gold Mine commenced processing operations in 2019, with the fully operational plant established in late 2020. Our firm played a pivotal role in providing comprehensive structural design and static projects for the steel structures employed in various critical processes.

The mine employs a state-of-the-art processing plant, integrating advanced methods to extract precious metals, primarily gold, from both oxide and sulfide orogenic gold ore sources. The meticulously designed steel structures support essential unit operations such as crushing, grinding, gravity concentration, cyanidation by leaching, carbon absorption, elution and stripping, electrowinning and smelting, and dewatering. The final tailings are efficiently managed through dry stacking in a Tailings Storage Facility.

The structural design prioritizes robustness, utilizing strategically placed channels and diagonals for optimal support and stability. Cross bracing, angled diagonals, and channel braces contribute to the structural integrity, accommodating temperature-induced expansion and contraction. The advanced processing plant incorporates modern techniques, progressing through stages of crushing, grinding, classification, CIP and gravity concentration circuits, culminating in smelting to produce gold and silver alloys. With a production capacity of approximately 400,000 tons per year, the Guyan Gold Mine stands as a testament to innovative mining practices and efficient structural design.
