Mining Construction Services, Mining Engineering, Minieral Processing Plant

With over 20 years of mining experience and a Class-A General Contracting Qualification for Mining Engineering, Xinhai has the expertise to undertake large-scale and complex civil engineering projects. We combine strong technical capabilities with efficient project management to ensure safe, on-time delivery and stable production for mining operations.

Scope of Mining Civil Construction Services

Civil Engineering Design for Mineral Processing Plants

Supported by Xinhai Mining Design Institute (Class-B Metallurgical Industry Qualification), we deliver civil design covering survey, plant layout, and equipment foundations. Our designs incorporate climatic, topographic, process, and environmental requirements to ensure safety, cost-effectiveness, and ease of operation and maintenance.

Civil Construction Services

We execute earthworks, concrete, masonry, steel structures, and supporting facilities such as water and power supply, roads, storage, offices, and living areas. Our construction team emphasizes quality control and safety supervision, ensuring progress even under challenging geological and climatic conditions.

Specialized Civil Construction Solutions

Steel-Structure Construction: In regions like Africa with high cement costs and tight schedules, we use steel structures for water tanks, ore bins, platforms, and equipment supports—reducing cost, shortening timelines, and improving flexibility.
Modular Steel Buildings: Quick-assembly color steel houses for laboratories, offices, dormitories, warehouses, workshops, and guard stations.
Integrated EPC Services: Civil works and equipment installation are managed under one contract. Once 60%–70% of civil works are completed, equipment installation can begin, ensuring parallel progress and shorter project schedules.

Advantages of Xinhai Civil Construction Engineering

Certified Expertise: Class-A General Contracting Qualification for mining engineering projects, providing authority and quality assurance.
Multidisciplinary Team: Over 80 specialists in civil, mining, mineral processing, electrical, automation, and steel-structure engineering, each with 20+ years of field experience.
Flexible Project Delivery: The "Design and Build" model allows for the overlapping design and construction, reducing project cycles and enabling faster production.
Construction & Installation Integration: Unified contracting ensures smooth coordination between civil works and equipment installation.
Sustainable & Safe: Full compliance with green mining policies, integrating water recycling, drainage, and safety systems for sustainable operations.

Project cases

Zimbabwe 2 Million T/A Lithium Processing Plant

Taking the Zimbabwe 2 Million T/A Lithium Mine Project as an example, Xinhai formulated a strict construction plan and ensured construction progress through the coordination of the project team. At the peak of the project construction, Xinhai dispatched a team of up to 423 people from China to the project site and hired over 1,000 local employees, achieving local employment by integrating local expertise with Xinhai's technical capabilities. These measures ensured that the project went from testing to successful trial production within a year, fully demonstrating Xinhai's speed in the implementation and execution of large and complex projects.

Concrete for the independent foundation of the coarse crushing workshop completed
Concrete pouring for the retaining wall foundation completed
Rebar binding for the plant foundation completed
Equipment foundation for the screening workshop completed
Formwork and rebar for the tailings thickener foundation completed
30% of the earthwork excavation for the flotation and grinding workshop completed

Henan 1800T/D Silver-Lead-Zinc-Gold Polymetallic Ore Flotation Expansion EPC Project

In the Henan 1800T/D Silver-Lead-Zinc-Gold Polymetallic Ore Flotation Expansion Plant project, Xinhai primarily provided mine EPC services. These services included Experimental Design, Complete Equipment Manufacturing and Installation, Engineering Construction, Steel Structure Fabrication and Installation (plant and steel platforms), and Process Commissioning. This project is a general contracting expansion for a Silver-Lead-Zinc-Gold polymetallic ore, aiming to increase the plant processing capacity. Currently, Xinhai has completed the Mine Design and Mine Engineering Construction Design for this project. Due to the short project duration, Xinhai simultaneously dismantled the existing plant and carried out reconstruction and expansion. Xinhai has already stationed at the project site to commence Mine Engineering Construction.
