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.

How does gypsum affect the atmosphere? Drywall production has a noticeable environmental impact. Processing the gypsum releases particulates from the gypsum powder in addition to sulfur dioxide, nitrous oxide, and carbon monoxide. Heating the gypsum also has a high energy cost. What is the effect of too much mining and …

Extractive Industries Impact (Hess and Slattery, 1999). There are a few individual reports scattered through the literature that address the envi-ronmental impacts of quarrying carbon-ate rocks in karst. In addition, there are reports that describe environmental impacts on karst from mining resources other than carbonate rock. Theories

1. Erosion. One of the effects of mining on the environment is erosion. The enormous Ok Tedi Mine in Papua New Guinea is a perfect example of how nearby areas can be significantly impacted by the erosion of exposed slopes, mine dumps, tailings dams, and the resulting siltation of drainages, creeks, and rivers.
