Improving DXRT Efficiency for Coal Beneficiation with Advanced Air Jets

Traditional heavy-media methods of coal beneficiation are expensive and have inherent environmental liabilities- X-ray separation of coal is a promising new technology that cuts the cost from mine to market with no environmental liabilities- The efficiency of x-ray separation of coal should be improved by employing air valves with faster response times, but no data exists to quantify that improvement- Coal beneficiation processes separate rock and coal- The economic benefit of a coal beneficiation process is directly related to the efficiency of the process, which is the measure of the capacity of the process to correctly classify pieces of coal and rock- This project measures the increase in efficiency gained by upgrading a component in the x-ray separation chamber- Further, it creates the dataset necessary for coal mining companies to assess the economic benefit of the improved efficiency-
