Environmental Risks of Mining

As dust, these minerals (such as the asbestos-like mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as "Black Lung" (Paul & Campbell, 2011). Another example of harmful dust generated is flue dust, a byproduct of mining fluorine.

What is Bitcoin Mining and How Does it Work? (2019 Updated)

Bitcoin mining is done by specialized computers. The role of miners is to secure the network and to process every Bitcoin transaction. Miners achieve this by solving a computational problem which allows them to chain together blocks of transactions (hence Bitcoin's famous "blockchain").. For this service, miners are rewarded with newly-created Bitcoins and transaction fees.

What is this "mathematical problem" that mining computers ...

Jun 17, 2014 · A hash output can be interpreted as a number (which might be very very large). When a miner hashes a block, his goal is for that number to fall within a certain numeric range. That range is what's known as the hashing difficulty. For example, if the current difficulty is low, maybe numbers 0 through 10000 are acceptable.
