  Introduction   Gold, a symbol of wealth and power, is a rare element that conducts heat and electricity well. This yellow metal is also highly malleable and easily shaped into various objects. Its diverse uses range from storing value and determining currency values to protecting wealth and making coins. Additionally, gold is used in the jewelry industry, to coat objects and increase their value, and in electronics, space exploration, medicine, and dentistry. The global production of gold is around 3,100 tonnes annually, with Europe contributing significantly. Before delving into its environmental impact, let's briefly explore the history of gold. Historical Perspective   Gold mining has a history spanning thousands of years, with large-scale operations dating back to ancient civilizations. Over time, mining methods have evolved from small-scale artisanal techniques to large-scale industrial operations, with gold sources spread across continents like Africa, Asia, N...

  Introduction  Let’s talk about coltan—a metallic ore that might not sound familiar but plays a huge role in your everyday life. Coltan is short for columbite-tantalite. Tantalum capacitors, those tiny components that power your smartphones, laptops, gaming consoles, and other electronic devices, use coltan as their raw material. Basically, without coltan, our tech wouldn’t work the way it does. Here’s the catch: a big chunk of the world’s coltan comes from the Democratic Republic of Congo (DRC), and the mining practices there often raise serious ethical issues. We’re talking about child labour, exploitation, and even funding armed conflicts. On top of that, mining coltan can harm the environment and disrupt local communities. That’s why it’s so important to think about where the materials in our gadgets come from. Ethical sourcing of coltan can help reduce these problems and make sure that the tech we rely on doesn’t come at the cost of human rights or the planet. Conflict-F...

Well, pull up a chair, because it turns out a seemingly ordinary black rock, called coltan, plays a surprisingly pivotal role. My digging into the history of this mineral took me way back to the 19th century and the heart of the Kingdom of Kongo, now the Democratic Republic of the Congo (DRC). The Minerals that constitute coltan were discovered were first discovered in the 19th century, though, at the time, its significance was not fully realized. Coltan is an ore containing niobium and tantalum. Niobium was discovered in 1801 by Charles Hatchett, and tantalum was discovered in 1802 by Anders Ekeberg Interestingly, while Europ...
