The Zimbabwe 700t/d gold mineral processing plant, as a comprehensive EPC+M+O project by Xinhai Mining, has delivered remarkable technological and economic benefits that have exceeded the client’s expectations. From advanced processing technologies that maximize gold recovery to efficient operations that minimize costs, this plant has become a profitable and sustainable asset in Zimbabwe’s gold mining sector. With a raw ore gold grade of up to 6g/t, the project’s success is a testament to Xinhai’s expertise in providing customized mining solutions.
The technological benefits of the plant are evident in its advanced process flow and equipment configuration. Xinhai’s customized process, which includes one-stage grinding-two-stage closed-circuit grinding and classification, gravity concentration, cyanidation, desorption electrolysis, smelting, and tailings dewatering, is designed to maximize gold recovery while ensuring operational efficiency. The integration of gravity concentration into the grinding and classification circuit, as mentioned earlier, is a key technological innovation that has reduced gold loss and improved recovery rates.
The plant’s equipment selection also contributes to its technological superiority. Xinhai used high-efficiency, energy-saving equipment throughout the plant, including advanced ball mills for grinding, centrifugal concentrators for gravity concentration, and state-of-the-art desorption electrolysis systems. These equipment not only improve processing efficiency but also reduce energy consumption and maintenance costs. For example, the energy-saving ball mills used in the grinding stage consume 15-20% less energy than traditional ball mills, resulting in significant cost savings over the long term. The desorption electrolysis system, which operates at high temperature and pressure, achieves a desorption efficiency of over 98%, ensuring that almost all gold adsorbed on the activated carbon is recovered.
Another technological benefit of the plant is its automation and digitalization. Xinhai incorporated advanced control systems into the plant’s operation, allowing for real-time monitoring and adjustment of process parameters. This automation reduces human error, improves operational stability, and allows for remote monitoring of the plant’s performance. The digital control system also collects and analyzes operational data, providing valuable insights that can be used to optimize the process flow and improve efficiency further.
The economic benefits of the plant are equally impressive. The high gold recovery rate, which exceeds 90%, is the primary driver of the plant’s profitability. With a raw ore gold grade of up to 6g/t, the plant is able to produce a significant amount of pure gold ingots each day, generating substantial revenue for the client. The integration of gravity concentration and advanced processing technologies has also reduced operational costs by minimizing gold loss and improving efficiency.
Cost savings are also achieved through the plant’s efficient design and operation. The EPC+M+O model, which ensures seamless coordination between project stages, has reduced construction and operational costs by eliminating delays and inefficiencies. The use of energy-saving equipment and water recycling systems has reduced utility costs, while the modular construction technique has shortened the construction duration, allowing the plant to start generating revenue earlier than expected.
The plant has also delivered significant socio-economic benefits to the local community. It has created over 200 direct employment opportunities, including positions for engineers, operators, and maintenance personnel, and many more indirect jobs in the surrounding communities. Xinhai also provided training to local workers, equipping them with valuable skills that can be used in the mining industry and beyond. This has not only improved the livelihoods of local residents but also contributed to the development of Zimbabwe’s mining sector.
In addition to its immediate economic benefits, the plant has long-term sustainability. The environmental protection measures implemented by Xinhai ensure that the plant’s operation does not harm the local environment, allowing for long-term, sustainable mining. The M+O stage of the EPC+M+O model ensures that the plant is operated and maintained to the highest standards, extending its lifespan and maximizing its long-term economic value.
In conclusion, the Zimbabwe 700t/d gold mineral processing plant has delivered significant technological and economic benefits, making it a benchmark project in African mining. Xinhai’s customized solutions, advanced technology, and integrated EPC+M+O model have ensured that the plant is efficient, profitable, and sustainable.
