The Botswana Institute for Technology Research and Innovation (BITRI) Specialty Chemicals team of Dr Mmilili Mapolelo and Biki Kalake, together with the former Lead Researcher – Nanomaterials Prof James Darkwa has published two chapters in a book titled “Treatise on Process Metallurgy, Volume 2B: Unit Processes.”  
 
The chapters titles are “Beneficiation, Physical Separation Processes” and “Botswana’s Untold Story of the Kalahari Dust Bowl to a Mecca of Diamond Mining”.  
 
The “Beneficiation, Physical Separation Processes” chapter highlights how physical separation methods such as sorting, screening, and gravity separation are utilised in the mining industry. The techniques are critical in the liberation minerals of interest from the gangue in the ore ready for the next stages of mineral processing. Though, there are many ways to separate minerals, the chapter focuses on the physical methods used in the real-life case studies featured in this volume. It’s all part of narrating the full story of how minerals ores are transformed into resources that power industries and economies. 
 
The “Botswana’s Untold Story of the Kalahari Dust Bowl to a Mecca of Diamond Mining” chapter captures how Botswana’s diamonds have been more than just “sparkle”. It presents how Botswana was transformed from one of the world’s poorest countries in 1960s to an upper middle-income success story of today due to responsible diamond resource management. 
 
The chapter highlights how Botswana built one of the world’s most respected diamond industries, producing conflict-free diamonds, using advanced technology and ethical practices. 
 
The Treatise on Process Metallurgy, Volume 2B: Unit Processes” book presents various unit processes with an emphasis on mineral processing, hydrometallurgy, and electrochemical materials and energy processes. The book highlights the roles of these processes in beneficiation, rare-earth extraction, utilization of lean resources, coal extraction, and biofuels, reflecting the shift toward green and electrochemical processes. Before minerals become useful products, a key step called beneficiation takes place—this is where unwanted material (called gangue) is removed from the valuable ore.
