COPPERBELT UNIVERSITY DISCOVERS AN INDIGENOUS BACTERIA TO LOWER MINERALS PRODUCTION COST
The Copperbelt University has identified an indigenous bacteria, Acidithiobacillus ferrooxidans strain DJN1 2021, which is capable of extracting mineral ores with low copper metal content at a relatively lower production cost.
The Bacteria discovered by a post graduate student pursuing a Master’s degree (M.Phil) in Chemical Engineering Davis John Nangali in collaboration with the Dean School of Mines and Mineral Sciences Professor John Siame was identified through the method of extracting mineral ores with low copper metal content at a relatively lower production cost using Bioleaching technology.
Professor Siame and Nangali devised the project to address issues leading to increase in production costs in mining such as the decline of mineral ore-quality. During the investigations, the team successfully developed a method of extracting valuable metals from mineral processing waste through the natural phenomena called Bioleaching.
Normally, in the process of extracting metals from underground deposits, many are left behind as the remaining elements are not valuable enough to extract, this is known as low-grade ore processing. To extract valuable metals from mineral processing waste, scientists began to study a natural phenomenon which is Bioleaching.
The Bioleaching process has moved beyond research and now being used in the mining industry. The process produces 5% of all Gold and 25% of all Copper extracted today and research is still underway on applying this method to other metal-containing waste.
The mining sector is one of the major drivers of economic development through provision of foreign direct investment and formal employment however, the industry is faced by numerous challenges such as the decline of mineral ore-quality resulting in high production costs. The discovery of this Bacteria brings a positive impact on the mining sector and paves way for the design of a pilot-scale bioleaching plant for use on a larger scale.
This is the success story of Davis John Nangali a Tanzanian national pursuing a Master’s degree (M.Phil) in Chemical Engineering under the Copperbelt University Africa Centre of Excellence for Sustainable Mining (CBU-ACESM).

The chair will facilitate collaboration between high-level, internationally-recognized researchers and teaching staff of the University and other institutions including the School of Education, University of Zambia (UNZA), School of Education, Mukuba University, as well as Open University of Tanzania, the Midlands state University (Zimbabwe), University of Zimbabwe (UZ) and the Swedish International Centre of Education for Sustainable Development and the Uppsala University Campus (Sweden) and other regions in the world.
The mandate of the Chair includes
Further, the Chair on MaSTESD will contribute towards the main areas of work of the UNESCO HQ Teacher Section that include the following:
Congratulations Prof. Shumba !!
Copperbelt University School of Medicine is dedicated into changing the lives of the community in Zambia by improving their health hence facilitating them to be more productive. In the week of July 10-15, 2022, Department of Dental and Clinical Sciences, of School of Medicine, Michael Chilufya sata campus conducted the community outreach to address oral health issues and COVID 19 prevention at Chitokoroki Ward in Zambezi District. The team comprised of Dental staff and students.
The community outreach conducted is a result of grant from HOPE FOUNDATION to support vulnerable population. It is awarded annually to organizations or individuals who are involved in bringing an impact to the vulnerable community. The CBU Dental Community Outreach to vulnerable community identified Chitokoroki ward in Zambezi district as a community vulnerable to oral diseases. The community outreach grant was awarded to Dr. Chrispinus Hakimu Mumena, who is the head of Department of Dental Clinical Sciences at Michael Chilufya Sata School of Medicine, (MCS-SOM). This the report of the first phase of implementation of the project that intended to address the community needs in the Chitokoroki ward.

Location of Chitokoroki:
Chitokoroki is a ward located in Zambezi district, a road distance of 700 km from Ndola and 40 km from the Zambezi town. It is located on the Zambezi river in Northwest province. It is 100% rural, and has a population of 4,199 (2010 census). Zambezi district has a population of 80, 306(https://www.citypopulation.de/en/zambia/wards/admin/0808__zambezi/). The word “ Chitokoroki” means a place of sand. As is the name, the place is composed of sand making some areas within difficult to reach by car. Only 4 wheels drive cars can access all areas. The means transport to the area from Zambezi town centre is by small cars carrying 7 people. The cars operate only during the day from morning to evening at 18 hours.
Chitokoroki Mission Hospital is a 200 bed hospital that serves a population of 150,000 in the Zambezi district” https://www.samaritanspurse.org/medical/mission-hospitals-chitokoloki-mission-hospital-chitokoloki-zambia/”. The public hospital which is the Zambezi district hospital which is located …. Km from Chitokoroki. The missionary hospital is operated partly with support from the visiting doctors from abroad and within the country. Most of the services are available except dental services. The specialized services are received intermittently through booking patients in a specific period when the Doctor or the team arrives. Specialized services are occasional.

CBU-SOM is located in Ndola district about 700 km from Chitokoroki. Dental clinical sciences department has specialized dentists and train BDS in the country. Due to operation from the central budget, there is limited budget to support any community outreach especially in the far areas such as Chitokoroki.
GOAL, AIMS AND OBJECTIVES OF THE PROJECT:
Purpose of the project: promote and improve the oral health and general wellbeing of the vulnerable population.
Aim 1: reduction of occurrence of oral diseases and COVID transmission through oral health education and hand washing hygiene among the community in Zambezi district
Aim 2: reduction of morbidity from preventable dental diseases
Aim 3: reduction of the burden of dental disease to the community

The department conveys sincerely gratitude to HOPE FOUNDATION for awarding the grant to this project. We acknowledge Chemi & Cortex (Distributor: Gourock Zambia LTD) for supporting the project with dentifrices (family size toothpaste and tooth brush). Every member of the community who received the dentifrices, smiled happily. We last but not least acknowledge CBU management for approving the use of the grant for the intended activities.
Thursday 16th June 2022, the Copperbelt University held discussions with Mopani Copper Mines PLC to revisit existing MOUs in a bid to ensure they benefit both parties.
Areas of collaboration to be strengthened include human resource development, Staff Support, intensive in-service training, student internships as well as teaching and research collaborations.
The said collaborations will span across multiple disciplines including Mining, Engineering, ICT and Business.
The Two (2) institutions have agreed to work on a road map for implementation of the revised collaborations.
