The ultimate goal of any mineral processing plant project is to achieve good economic benefits, while also bringing positive social and industrial benefits to the local area. The Tanzania 1,200t/d gold mineral processing plant project undertaken by Xinhai Mining has achieved remarkable technological, economic, social and industrial benefits since its operation. The plant’s stable production capacity, high leaching rate and efficient operation have not only brought considerable economic returns to the customer, but also promoted the development of Tanzania’s mining industry, created employment opportunities and driven the progress of related industries, becoming a model of win-win cooperation between Chinese mining enterprises and African countries.
The technological benefits of the project are mainly reflected in the high leaching rate and stable production capacity. The project adopts the all-slime cyanidation process customized by Xinhai, and through the optimization of each production stage, the leaching rate of sulfide ore reaches 93.75% and that of oxide ore reaches 91.58%, which are higher than the average level of the same type of gold projects in the world. This high leaching rate ensures the full utilization of gold resources, avoiding the waste of valuable elements. At the same time, the plant’s design production capacity is 1,200t/d, and after being put into operation, it quickly reached and maintained the design capacity, with stable operation. The advanced equipment configuration and scientific process design make the plant’s equipment operation rate reach more than 95%, the downtime is greatly reduced, and the overall production efficiency is significantly improved.
The remarkable economic benefits are the core embodiment of the project’s success. For the customer, the high leaching rate and stable production capacity ensure the continuous output of finished gold, and the low production cost brought by the optimized process and equipment configuration further improves the project’s profit margin. The sulfide ore of the project has a high gold grade of 10.7g/t, and the high leaching rate enables the customer to recover more gold with the same ore processing capacity, bringing considerable economic returns. In addition, Xinhai’s EPC+M+O service mode effectively shortens the project’s construction period, enabling the plant to be put into production on schedule and the customer to obtain investment returns in advance, shortening the investment recovery cycle.
For Tanzania, the project has brought positive social benefits, the most prominent of which is the promotion of local employment. The construction and operation of the plant have created a large number of local jobs, including construction workers, operation and maintenance personnel, management personnel and technical personnel, solving the employment problem of hundreds of local residents. Xinhai also carried out professional technical training for local personnel, helping them master the skills of mineral processing equipment operation, process adjustment and equipment maintenance, improving their employment ability and income level, and promoting the improvement of local people’s living standards.
In addition, the project also promotes the development of local related industries. The operation of the plant requires a large number of construction materials, logistics transportation, water and electricity supply and other supporting services, which drives the development of local transportation, logistics, building materials, catering and other related industries, forming a radiation-driven effect on the local economy. Xinhai also purchased a large number of local materials and services during the project implementation, promoting the development of local enterprises and stimulating the vitality of the local economy.
The project also makes an important contribution to the development of Tanzania’s mining industry. Before the implementation of the project, the local mining industry was relatively backward in terms of mineral processing technology and project management. Xinhai introduced advanced all-slime cyanidation technology, efficient mineral processing equipment and scientific project management experience to Tanzania through this project, promoting the technological progress and industrial upgrading of the local mining industry. The successful operation of the project provides a valuable reference for the construction of similar large-scale gold processing plants in Tanzania, helping the local mining industry move towards a more efficient, green and sustainable development path.
In terms of environmental protection, the project also achieves good ecological benefits. Xinhai adopted a series of environmental protection measures in the project design and operation, including dust removal, wastewater treatment and tailings harmless treatment, ensuring that the production process meets Tanzania’s strict environmental protection standards, minimizing the impact on the local ecological environment. This green development mode also sets a good example for the local mining industry, promoting the concept of green mining in Tanzania.
The Tanzania 1,200t/d gold mineral processing plant project is a successful case of win-win cooperation between Xinhai and Tanzania. It not only brings considerable economic benefits to the customer, but also promotes the economic development, industrial upgrading and employment improvement of Tanzania, demonstrating the positive role of Chinese mining enterprises in helping African countries develop mineral resources. In the future, Xinhai will continue to uphold the concept of win-win cooperation, and provide more high-quality mineral processing solutions for global mining customers, making greater contributions to the sustainable development of the global mining industry.
