Tanzania, a country rich in gold resources in East Africa, has become a key market for global mining investment with its abundant mineral reserves and improving investment environment. Against this backdrop, Xinhai Mining, a leading provider of mineral processing complete solutions, successfully undertook the Tanzania 1,200t/d gold mineral processing plant project, an integrated EPC+M+O project that integrates Engineering, Procurement, Construction, Mining Management and Operation. This project, with its unique ore properties and high production scale, has become a benchmark for efficient and sustainable gold mining in Tanzania, demonstrating Xinhai’s strong comprehensive strength in the global mining service field.
The Tanzania 1,200t/d gold project is distinctive in its ore composition: it consists of sulfide ore with a gold grade of 10.7g/t and oxide ore with a gold grade of 2.4g/t, with gold as the only valuable element. This ore characteristics put forward special requirements for the mineral processing process—how to efficiently recover gold from two types of ore with very different grades and properties, while ensuring the stability of production capacity and economic benefits, has become the core challenge of the project. Xinhai, relying on its years of experience in gold mineral processing and rich overseas project practice, customized a targeted overall solution for the project, and the EPC+M+O service mode adopted in the project has laid a solid foundation for the smooth implementation and long-term operation of the project.
The EPC+M+O mode adopted in this project is an advanced service mode in the current large-scale mineral processing plant construction, which solves the pain points of customers in coordinating multiple links such as design, construction and operation. For the Tanzania project, Xinhai took full responsibility for the whole process from the initial project research, process design, equipment procurement and manufacturing, on-site construction and installation, to the later equipment commissioning, trial operation, operation management and technical support. This integrated service mode not only reduces the communication cost and project risk for customers, but also ensures the consistency and efficiency of the whole project process, enabling the project to be put into production on schedule and achieve expected benefits.
In the early stage of the project, Xinhai’s professional technical team conducted in-depth on-site investigations in Tanzania, fully understanding the local natural environment, transportation conditions, industrial supporting facilities and relevant mining policies and regulations. Tanzania has strict requirements on environmental protection and production safety in the mining industry, and Xinhai integrated environmental protection and safety concepts into every link of project design and construction. In view of the local water and electricity resources and labor conditions, Xinhai optimized the process design and equipment configuration to adapt to the local actual situation, reducing the project’s operation cost and improving the adaptability of the plant.
In the process of project implementation, Xinhai adhered to the principles of high quality, high efficiency and safety, and strictly controlled every link. The professional construction team and installation team sent by Xinhai have rich overseas project experience, and strictly constructed and installed in accordance with the design drawings and international standards, ensuring the construction quality. At the same time, Xinhai established a special project management team to track the project progress in real time, coordinate the cooperation between various teams, and solve the problems encountered in the construction process in a timely manner, ensuring the smooth progress of the project.
After the completion of the project, Xinhai continued to provide operation management and technical support services. The professional operation management team formulated scientific operation plans, optimized process parameters, and ensured the stable operation of the plant. The technical support team provided regular technical training and on-site guidance for the local operation personnel, helping them master the operation skills of equipment and process, and realizing the independent operation and management of the plant by the customer. Up to now, the Tanzania 1,200t/d gold processing plant has been operating stably, with the leaching rate of sulfide ore and oxide ore reaching 93.75% and 91.58% respectively, which has been highly recognized by the customer.
This project is not only a successful practice of Xinhai’s EPC+M+O mode in East Africa, but also a positive contribution to the development of Tanzania’s mining industry. It has introduced advanced mineral processing technology and management experience to Tanzania, promoted the technological progress of the local mining industry, created a large number of local employment opportunities, and driven the development of related industries. In the future, Xinhai will continue to uphold the concept of technological innovation and sustainable development, and provide more high-quality mineral processing solutions for global mining customers, helping more mining projects achieve efficient and green development.
