But, recently a Montana mine chose to pave their tunnels in asphalt to protect their workers and profits. In the world of precious metal mining, commodities such as platinum, gold, silver or copper are typically what come to mind.

Process and Dust Control. The process control palliative is an application of a diluted asphalt, petroleum or organic emulsion sprayed directly on a stockpile or misted during the stockpiling process.
