Mining is bad for health: a voyage of discovery SpringerLink

2019-7-9  Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners. I look at mining and health from various personal perspectives:

The Environmental Impact of Spodumene Mining

2021-9-16  The spodumene moves to a dryer and kiln that operate at about 1,000°C. This process converts the mineral into an easy-to-extract form using acid. This stage in the process also has the potential to release chemicals in the environment, some of which can be attributed to the fuel quality, calciner design, and emission abatement steps.
