Mining DRC-Zambia has been providing insightful content to decision-makers and procurers within the Southern African mining sector and have developed a loyal readership in that time. In this issue read more about airborne geophysical techniques and their use in mineral exploration. It also takes a closer look at recent developments and new innovations in the oil mist eliminators sectors. We examine the latest developments in the DRC with regards to legislation and new project developments at Katanga. We then take a look at the critical and evolving energy sector and its contribution to mining sustainability. Global power leader Cummins has introduced the new C450 D5, as part of its QSG12 series diesel gensets for the commercial and industrial markets. is latest product offers more power for less space by delivering a much higher power density and a more reliable power solution. We hope that this issue of 1st Mining DRC-Zambia helps enlighten its readers, answer some of their questions, and inspire them to look for more answers. If by informing its readers our magazine can help propel the mining industry to greater heights, this is only the beginning of its long journey. Bertha M. Editor

DRC mining sector to sustain growth despite unrest
unrest will both disrupt the ow of goods throughout the country and reduce consumer demand for these goods. is will only be exacerbated by a pullback in government aid. Grants amount to around 8.2% of total revenues, however the recent political crisis has soured relations between DRC and many of its largest donors. We see signi cant risks that donor countries will reduce or withhold aid due to disagreements with Kabila and given limited alternative sources of nancing, this is most likely to translate into a pullback by the government in capital spending. While much of the economy is poised to remain in the doldrums, mining sector activity is likely to be a bright spot for the DRC, offering crucial tailwinds to headline growth.

Products & SERVICES For one of the sections where instabilities were of concern, a simple drapery solution was in order because of the amount of debris and block sizes expected to travel down the slope. e mine selected Maccaferri's Steelgrid® HR50 rockfall drapery mesh for the 4500 m² area. With the other section of the mine where instabilities were also noticed, the space and energy requirements were completely different. For mitigation of this section a simple drapery approach was not the optimum solution. erefore, for this section a Maccaferri dynamic rockfall barrier (RMS050 ICAT/2 PLUS) with an energy rating of 500 kJ, 150 m long and 3m high was chosen. e installation of the rockfall mitigation solutions are being done by Marshall developments.

olberg Manufacturing, Inc is a ltration and separation company
that specializes in the protection of rotating equipment used in
process industries, mining applications, land ll gas to energy and
the power generation segment. Solberg's products are manufactured in the USA, Europe and Asia and supplied throughout the world, including Africa, through an expansive network of direct sales offices and reseller organizations. At a time when engine and turbine operators faced increasing regulatory requirements in North America and Europe regarding the cleanup of gearbox, crankcase and lubrication system emissions, Solberg became a trusted source for Oil Mist Elimination systems and products. rough use and application of Solberg's Oil Mist Elimination solutions, not only were operators able to meet increasingly stringent requirements of local and national environmental regulations, they were also able to improve equipment performance and reduce costly maintenance issues including wear and tear on turbos and other engine and drive train components. In critical continuous duty applications, equipment uptime is a priority. Solberg's oil mist eliminators are engineered to help engine and equipment operators maximize uptime and reduce maintenance. ”We www.fmdrc-zambia.com

It is Solberg's commitment to provide engine and turbine operators in Africa with the products and support they need to succeed. ” said Clint Browning, Vice President of Sales for the company. When it comes to the Solberg brand, equipment operators can count on its Oil Mist Eliminators to be well built and suitable for extreme duty applications. With a removal efficiency of 99.97% for 0.3 micron particle size, harmful emissions are signi cantly reduced allowing equipment to operate trouble free for extended time periods. “With a properly sized Oil Mist Eliminator, Operators can recover the engine or lubrication system oil and realize signi cant savings in oil consumption. ey can recycle the oil, clean it, and send it back into their system for reuse. We have many options available to our customers that facilitate and optimize a systems performance” explained Mark Smith, Technical Sales Manager for EU Operations. “Our approach to providing customers the right solution, not just any solution, really differentiates Solberg. With thousands of Oil Mist Eliminators installed around the world, we have the know how to make the right recommendation,” said Smith. Solberg Manufacturing designs turnkey solutions, meaning all that the operator has to do is connect their equipment inputs and outputs to the Solberg Oil Mist Eliminator unit and it's ready to operate. Optional designs include automated vacuum regulation and built in bypass features that help ensure trouble free operation. Further, Solberg Oil Mist Eliminators can be designed for outdoor use and accommodate a range of ambient temperatures. e fact that Solberg designs and makes all of its own elements, for any type of scenario, provides the ability to quickly specify the right solution for the most challenging operating environments.

Higher power requires more copper because of the need for larger gauge wires, so a faster uptake in direct current (DC) charging would signi cantly increase copper demand. Equally, policies requiring buildings to have charging facilities installed would have a major impact.
With the conversation around electric vehicles and plug in electric vehicles continuing to grow around the world, what impact will this have on the demand for copper? New research from the International Copper Association (ICA) has revealed that the rising number of plug-in electric vehicles (PEVs) will drive a total copper demand of 560,000 tonnes of copper through to 2027. New demand for PEVs will also see an increase to 102,000 tonnes due to the “crucial role” that

have come at a better time. On the downside, Africa struggles with a disease burden, drought and a fall armyworm infestation, but on the upside we are extremely rich in mineral and natural resources, and have been blessed with ideal climate for agricultural production. Despite our lack of capital and infrastructure, we have an abundance of manpower, with research indicating that 60% of our youth are under the age of 30. Africa's population continues to soar at a phenomenal rate, and accounts for 16% of the world's population. At the heart of this lies eager innovative minds with digital expertise and a natural knack for technology. is is what we should be leveraging. Aer all, innovation is without a doubt the key to solving our troubles and seeking solutions to the burdens we face. A pre-requisite for structural transformation and sustainable development depends on African countries becoming innovation-driven economies in the emerging world. It requires an accelerated pace of change and hypercompetitive economies. Innovation needs to become a way of life and through which we can develop solutions to address challenges with development, poverty, health, food security, climate change, governance, productivity, water and so forth. We need to cultivate our ideas, our youth and our technology to mature Africa and catch up to the rest of the world in the quantum age. Africa www.fmdrc-zambia.com
