The mining and mineral processing industries produce a variety of gaseous and particulate emissions, oftentimes in a combined air stream.
Raw materials, such as quartz and silicon are extracted from the ground and purified by chemical processes.
The highly purified materials, such as polysilicon, are used in the solar and electronics industry for a variety of purposes.
HEIL engineers have designed multistage systems to control the chemical emissions with high removal efficiency.
Some of the compounds that HEIL systems control in the mining, mineral, and precious metals refining industry include:
