Abstract For the last 500 years, the West has mapped Africa as a source of raw materials, disrupted vibrant African value addition, and arrogated itself as the place where industrial revolutions (value addition) happen. This strategy is clearly traceable from the transatlantic slave trade, continuing through European colonialism, to the current …

Mining industries provide many of the raw materials for equipment we use daily, from aluminum cans up to electronic chips of cell phones and computers. To arrive here, metal mining steadily increased over the centuries, with occasional "rushes" for several minerals (silver, gold, radium, etc.) which occurred in connection with booms in …

Today, there are two main ways to pull lithium from the ground. Until recently, most lithium mining occurred in Chile, where lithium is extracted from brines: salty liquid found at the Earth's surface or underground. To extract lithium, that liquid is pumped from the earth and then placed in pools where the water can evaporate, leaving behind ...

For the recovery of New World silver, the Patio process was employed. Silver-bearing ore was ground and then mixed with salt, roasted copper ore, and mercury. The mixing was accomplished by tethering mules to a central post on a paved patio (hence the name of the process) and compelling them to walk in a circle through the mixture. The silver ...
