Young Innovators Develop Technology to Make Small-Scale Mining Safer, Cleaner and More Efficient
By Selemani Nambimbi & Donald Boneka, CMU
A team of University of Dar es Salaam (UDSM) students is developing an automated mineral processing technology that could transform the way Tanzania's small-scale miners extract and process minerals, improving productivity while reducing environmental and health risks.
The innovation, unveiled during the University's 11th Research and Innovation Week, was developed by Bernadetha Mwacha, Mackson Mwakalange, Shedrack Malack and Ivvo Sosthnes from the School of Mines and Geosciences (SoMG), in collaboration with Dennis Mwasonya from the College of Information and Communication Technologies (CoICT).
Designed to address long-standing challenges facing artisanal and small-scale miners, the technology automates key mineral processing activities, helping miners improve efficiency while minimizing exposure to hazardous working conditions and reducing environmental pollution.
Speaking during the exhibition, Bernadetha Mwacha said the team was motivated by the realities faced by many small-scale mining communities across the country.
"Our innovation seeks to make mineral processing safer, more efficient and environmentally friendly. We believe technology can play a key role in improving productivity while protecting both miners and the environment," she said.
For the young innovators, the project represents more than a technological solution. It is an opportunity to contribute practical answers to challenges affecting one of Tanzania's most important economic sectors.
Their efforts attracted the attention of the Minister for Minerals, Hon. Anthony Mavunde (MP), who visited the exhibition and directed that the technology be demonstrated to small-scale mining communities for further assessment and possible adoption.
The students say the positive reception has strengthened their determination to take the innovation to the next level. However, they acknowledge that additional funding is needed to acquire equipment, conduct advanced testing and prepare the technology for large-scale deployment.
The mining innovation was among several solutions showcased by students and researchers seeking to address national development challenges through science and technology.
Smart Get: a digital attendance and visitor management system
Also drawing attention was Smart Get, a digital attendance and visitor management system developed by experts and trainees at the UDSM Computer Centre. The platform replaces traditional paper-based registration systems by electronically recording visitors' entry and exit times and other essential information through a smart-card-enabled system.
According to the developers, the technology improves efficiency, enhances institutional security and reduces administrative costs while supporting Tanzania's broader digital transformation agenda.
The innovations reflect a growing culture of problem-solving and entrepreneurship at UDSM, where students and researchers are increasingly developing home-grown technologies aimed at improving livelihoods, strengthening industries and supporting sustainable development.
As Tanzania seeks to accelerate industrialization, digital transformation and value addition in key sectors such as mining, universities are playing an increasingly important role in generating solutions that respond directly to community and industry needs.
For the student innovators behind the automated mineral processing technology, the goal is simple: to ensure that scientific knowledge developed in classrooms and laboratories translates into real-world impact for Tanzanians.
Their innovation offers a glimpse of how young researchers are helping shape the future of mining—one that is safer, cleaner and driven by technology.
