With the advancement of science and technology, digitalization,
intelligentization, and other innovations are increasingly being applied in
modern copper ore dressing plants. The traditional subcontracting model can
hardly meet the needs of modern mining enterprises. The EPCM+O (Engineering,
Procurement, Construction Management + Operation) general contracting model
offers a comprehensive solution for the construction and operation of copper ore
dressing plants, making it a preferred choice for mining companies.

01What is the EPCM+O model of copper ore Dressing Projects?
The EPCM+O model is a mining industry chain management model that integrates
engineering, procurement, construction management and operation. The
characteristic of this model is that it manages all stages of the project in a
unified manner, achieving seamless connection from project planning to
operation. After years of project practice, the application of this model in the
mining field has gradually matured, especially in the construction and operation
of copper ore dressing plants, showing many advantages.
02Advantages of the EPCM+O Model in Copper Ore Processing
1. Project Management Advantages
The core purpose of the EPCM+O model is to have a general contractor
responsible for the full-process management of the project. This approach
eliminates the need for multi-party coordination seen in traditional models and
prevents issues such as buck-passing and disputes. Under the EPCM+O model,
responsibilities within the copper ore dressing plant are clearly defined,
ensuring the efficient operation of all stages.

2. Cost Control Advantage
Compared with the traditional subcontracting model, the EPCM+O model reduces
intermediate steps through one-stop services, thereby effectively lowering
project costs. The general contractor can optimize the process flow and select
more cost-effective equipment and materials during the design phase. In
addition, centralized procurement and optimized supply chain management allow
the general contractor to further reduce procurement expenses.
The EPCM+O model also minimizes the impact of project risks on costs through
a risk-sharing mechanism. For example, the general contractor may adopt
fixed-price contracts to ensure cost stability for the owner and avoid budget
overruns caused by market price fluctuations or construction delays.
3. Technical and Quality Advantages
The advantages of the EPCM+O model are not only reflected in project
management and cost control, but also in technological innovation and quality
assurance. The general contractor typically has a professional technical team
with expertise across multiple areas, including mineral processing design,
equipment R&D and procurement, engineering construction, and operational
management. By integrating cutting-edge technologies, the general contractor can
offer customers advanced mineral processing solutions and optimal equipment
selection.

4. Operational Advantages
Another significant advantage of the EPCM+O model lies in its effectiveness
during the operational stage. The general contractor becomes involved in
operational planning early in the project construction process, ensuring a
seamless transition from construction to operation.
The general contractor's operations team typically possesses extensive
industry experience and can enhance the efficiency of the mineral processing
plant through optimized production processes, equipment maintenance, and
personnel management. For instance, with the help of intelligent equipment
management systems, the operations team can monitor equipment performance in
real time, detect potential failures in advance, and minimize downtime.
03Cases of the EPCM+O Model in Copper Ore Processing
1. Myanmar 500t/d Copper Processing Case

The Myanmar 500t/d copper processing case is a full-industry-chain service
project provided by Xinhai Mining. The services mainly include beneficiation
testing, process design, equipment manufacturing, packaging and shipping,
installation and commissioning, and employee training.
Based on test results, Xinhai adopted a closed-circuit process of crushing,
grinding and classification, followed by one-stage roughing, two-stage cleaning,
and three-stage scavenging flotation.
The project adopted the EPCM+O model, which shortened the project cycle,
reduced investment costs during plant construction, and improved the
beneficiation recovery rate — truly achieving the effect of "killing two birds
with one stone."
2. Pakistan 1500t/d Copper Processing Case

A large copper ore dressing plant in Pakistan adopted the EPCM+O general
contracting model for both construction and operation. Xinhai selected a
flotation process consisting of one-stage roughing, two-stage scavenging, and
two-stage cleaning through optimized design.
Xinhai provided services including equipment manufacturing, procurement, and
installation. Through centralized procurement and optimized supply chain
management, the company reduced equipment procurement costs for the client.
During the construction phase, Xinhai maintained strict quality control to
ensure on-time project delivery. In the operation phase, Xinhai improved mineral
processing efficiency by optimizing the production process through an
intelligent management system.
