Minerals | Free Full-Text | Jigging: A Review of ...

For centuries, jigging has been a workhorse of the mineral processing industry. Recently, it has also found its way into the recycling industry, and the increasing concerns related to water usage has led to a renewed interest in dry jigging. However, the current scenario of increasing ore complexity and the advent of smart sensor technologies, such as sensor-based sorting (SBS), has ...

Coal Cleaning - an overview | ScienceDirect Topics

Coal Cleaning. Coal cleaning is an option for removing mercury from the coal prior to utilization. Of the more than 1 billion short tons of coal mined each year in the United States, about 600 to 650 million short tons are processed to some degree [91 ]. Coal cleaning removes pyritic sulfur and ash. Mercury tends to have a strong inorganic ...
