How Did the Tanzanian Gold Mining Project Ensure Power Supply and Tailings Disposal?
On November 23, 2021, the mine in Tanzania officially commenced operation. Over the past three years, the project department has triumphantly surmounted challenges like the epidemic’s impact, a dearth of engineering personnel, and a shortage of essential equipment. They’ve completed the mining project, the construction of the concentrator equipped with advanced gold extraction machines, and the building of the tailings pond. Once fully operational, it will be a 1,200-ton-per-day gold recovery plant. Chinese state-owned enterprises have invested in and constructed the largest mining project in Tanzania so far.
The project is nestled in Xinyangga Province, northwestern Tanzania. The mine development project was in the preparatory stage for construction in 2017, and the project base officially kicked off civil construction in October 2018.
Mine construction engineering serves as the vanguard of mining engineering. In July 2019, the project got underway. By the end of 2020, to meet the production demands of the plant equipped with high-efficiency gold processing machines, the project site technicians, in collaboration with the domestic expert team, made a strategic decision to shift from the slope + inclined shaft development mode to the mixed shaft + modified inclined shaft mode. This not only bought more time for shaft construction but also effectively cut down on the overall project costs.
In mid-November this year, the inclined shaft was renovated, and the ore supply has been steadily on the rise.
To guarantee a stable power supply post-project production, in early 2021, through the communication and negotiation efforts of the project department, the Tanzanian Ministry of Energy constructed a 47-kilometer-long high-voltage dedicated line for the mine. All in all, the gold recovery plant saved over 30 million yuan.
The tailings pond functions as the excretion site for mine production, and the proper disposal of harmful tailings is the linchpin of green mine construction. Designed by a domestic authoritative organization and approved by relevant Tanzanian authorities, the tailings pond officially broke ground in June this year. After more than three months of intensive construction, over 200,000 cubic meters of earth were excavated, 100,000 cubic meters of dams were built, and 260,000 square meters of geomembrane were laid. The construction was finally successfully wrapped up before the rainy season.
At the same time, to achieve deep integration into the local community, while the project is fully immersed in mine construction, it has also carried out in-depth cooperation with the local government to offer various forms of assistance to the local people’s livelihood.
Let’s continue to support and promote such remarkable mining projects that contribute to both resource development and local community well-being. If you’re interested in similar mining endeavors or have any ideas on improving gold recovery processes, join us and let’s make a difference together!
