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.

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.

Indeed, our mining team expects DRC to be one of the fastest growing major mining markets in the world in the coming quarters, largely on the back of an increase in copper and cobaltproduction. e sector is expected to receive a boost from the completion of renovation works at Glencore's copper and cobalt-producing Katanga

Botswana rolls out allminerals exploration project

T

he government of Botswana has commenced a 3 year-long exploration programme that seeks to establish all types and quantities of minerals that occur beneath its Kalahari desert

sands.

Local media reports said the aim of the wide-ranging exploration programme is to produce a new geological map and mineral catalogues that will attract and help potential investors make informed decisions.

Speci cally, the programme seeks to establish battery metal mineralisation to ensure that the country bene ts from the fastemerging, battery-driven electric vehicle and information and communication technology gadget industries.e project will focus on the study of granites, which are natural bearers of lithium ores. e government hopes the information gathered during the study will help diversify the mineral-based economy to end over-reliance on diamond mining. e results of the exercise, to be led by the Botswana Geo-Sciences Institute, will be used to update mineralisation data produced in the last government-sanctioned geological sampling exercise in 1997.

In its March quarter results statement released on April 27 the company said, “a process for provision of all relevant documentation has been agreed between the company and the ZRA. Based on the work undertaken to date, the

According to chairman and CEO Philip Pascal, “the process is approximately two-thirds complete by value and has not identi ed any material errors. e company unequivocally refutes the assessment, is committed to transparency and continued engagement with the ZRA on the issue.”

Like several other mining companies operating in a number of African jurisdictions – such as Randgold Resources/AngloGold Ashanti's Kibali mine in the Democratic Republic of Congo – First Quantum is owed substantial amounts in value-added tax (VAT) repayments from government. e quarterly report noted that the “amount of VAT accrued by the company's Zambian

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.

process was developed on a commercial scale early in the 20th century to remove very ne mineral particles that formerly had gone to waste in gravity concentration plants. Flotation has now become the most widely used process for extracting many minerals from their ores.

Most kinds of minerals require coating with a water repellent to make them oat. By coating the minerals with small amounts of chemicals or oils, nely ground particles of the minerals remain unwetted and will thus adhere to air bubbles. e mineral particles are coated by agitating a pulp of ore, water, and suitable chemicals; the latter bind to the surface of the mineral particles and make them hydrophobic. e unwetted particles adhere to air bubbles and are carried to the upper surface of the pulp,

wiring installed to connect chargers to electrical panels, meaning a change in deployment—from charging at home to commercial charging—could require four to nine times as much copper, depending on the extent of the shi,' says John Gartner, Director at Navigant Research. e same is true for the type of charger used.

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. Aer 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
