Cuprum or Copper (Cu) is the oldest known used metal to date. A greener, healthier and more sustainable future also relies on the use of copper. The wide range use of copper lies in its property of superior electrical and thermal conductivity, highly durable capabilities and can be 100% recycled without any loss in performance.

Copper Metal fits seamlessly in our philosophy of “sustainable growth”. The copper industry is making a positive impact on areas of critical societal concern, such as energy efficiency, security, climate change mitigation, public health, food supply, green building and many more.

Copper is recognized as a key material for low carbon solutions such as renewable energy and electric vehicles. Renewable energy systems use up to 12 times more copper than conventional power systems. One tonne of copper used in rotating machines—such as an electric motor or a wind turbine—saves 7,500 tonnes of CO2 emissions over its lifetime. By 2030, Copper could reduce the world’s carbon footprint by 16%. Copper consumption is predicted to rise more than 40% by 2035. Partly driven by green technologies—like solar and wind power, and electric vehicles—additional demand will be met through mining and recycling.

Zumran’s operations are located in the Central African Copper Copperbelt ( CACB) of Zambia and Congo which is the world’s largest and richest sedimentary hosted copper bearing Geological province. This gives Zumran a strategic advantage for future Copper Metal production.

(Co)Cobalt known as the chemical abbreviation (Co) is a silver-white metallic element and is one of those often-neglected metals with a host of uses and dynamic properties. It is mainly obtained as a by-product of nickel and copper mining activities and one of the most common uses of Cobalt is used in the preparation of magnetic and high-strength alloys.

The uses of Cobalt is everywhere, even though we may not realise it. The world today is moving towards zero carbon and green and renewable energy solutions. We currently create energy from the wind, water and sun wherever we can but unfortunately cannot rely on the environmental conditions to remain consistent. Therefore, when your electricity supply is intermittent – as is the case with renewables – electricity storage becomes essential. Cobalt containing batteries are again the solution. Such batteries also give the modern electric vehicles the range and durability that consumers need.

Cobalt is also used in the strongest kinds of permanent magnets – a requirement of wind turbines, meaning it is a vital part of making wind turbines work as well! It is also a dominant metal for semi-conductors – the heart of the chips that make modern electronics work. Lithium-ion batteries are the heart of electronic devices like phones, laptops and tablets. Cobalt is the main component in these batteries and as we move towards greater digitalization – from transport to smart homesand smart cities – we are going to need cobalt.

When we talk about “desulphurization” of oil contributing to a cleaner environment, a significant use of cobalt acts as catalysts in the desulphurization process.

When you next get on a plane or perhaps if you one day go into space in a rocket – you might well have cobalt to thank for getting you to your destination safely.

When it comes to the field of medical sciences including prosthetic implants like hip or knee replacements, Cobalt is a metal that is widely used. As a component in powerful magnets, cobalt also used to enable techniques like magnetic resonance imaging and the imaging of damage to the brain, as well as to sterilize medical and dental equipment before use.

Tin is a metal known to mankind since Bronze age. Bronze is a alloy of copper with 5% Tin. Bronze melts at lower temperature, which makes it easy to work, but its a metal much harder, and ideal for tools and weapons. Peoples of Egypt, Mesopotamia, and the Indus valley started using it extensively around 3000 BC.

Tin has many uses: it takes a high polish and is used as corrosion preventive coating such as in tin cans. Many alloys of tin are important, such as soft solder, pewter, bronze and phosphor bronze. A niobium-tin alloy is used for superconducting magnets.

Most window glass is made by floating molten glass on molten tin to produce a flat surface. Tin salts sprayed onto glass are used to produce electrically conductive coatings.

The most important tin salt used is tin(II) chloride, which is used as a reducing agent and as a mordant for dyeing calico and silk. Tin(IV) oxide is used for ceramics and gas sensors. Zinc stannate (Zn2SnO4) is a fire-retardant used in plastics.

Future demand of Tin will be driven by its need in automobile, food packaging, mobile, electronics, solar panels and animal health care.

Zambia has less explored the Tin belt but the DRC, Uganda, Rwanda, Tanzania are good producers of Tin Ore. Zumran is the pioneered producer of Tin in Zambia. We are securing Exploration Licences and also ethically produced ore from Zambia with non conflict certificate. We produce 99.99% Pure Tin Metal in our Processing Plant and in the future we also have a plan to produce Tungsten and Tantalum from the same plant.
