Shandong Xinhai Mining Group — Founded in 1997

Who We Are

Shandong Xinhai Mining Group Co., Ltd. is a mining services company delivering gold milling and processing plants around the world. Founded in 1997, Xinhai has served more than 2,500 mines and delivered more than 600 Mine EPC+M+O projects across more than 100 countries and regions.

We operate as one accountable partner across the full project lifecycle — ore testwork, plant design, equipment manufacturing, construction, installation and commissioning, and optional operation management.

Gold-Specific Capability

Our gold processing expertise covers the full recovery toolbox: gravity concentration, flotation, and CIL/CIP cyanidation, plus heap leaching. We support projects from small-scale to 15,000 t/d gold processing plants.

• Flotation, CIL/CIP cyanidation and heap leaching routes
• Ball mills up to 7 m diameter
• Flotation cells up to 320 m³
• Leaching tanks up to 20 m × 20 m
• Thickeners up to 100 m diameter

Testwork & Design

Every gold plant starts in the laboratory. Our CNAS-accredited laboratory and industrial-scale pilot test base carry out mineral processing studies on more than 70 ore types, performing approximately 5,000 element analyses each month and around 200 mineral-processing studies a year.

The Mine Design Institute holds a Class B qualification in China's metallurgical industry, and we design to international standards including JORC, NI 43-101 and VALMIN.

Manufacturing

Across three intelligent manufacturing bases totalling approximately 110,000 m², Xinhai manufactures and supplies more than 1,000 equipment types — covering crushing, milling, flotation, leaching and thickening for gold plants up to 50,000 t/d.
