Large-scale application of filled coal mining technology has long been limited by conditions such as the cost filling. Compared to traditional filling materials, flotation tailing materials (CFTFM) offers advantages low and excellent performance. The Box–Behnken response surface method was used investigate influence properties on mechanical hydration mechanisms material. Ash content, blending, ...

Abstract Deinked pulp flotation column has been applied in wastepaper recycling. Bubble size in deinked pulp flotation column is very important during the flotation process. In this paper, bubble images of deinked pulp flotation column were first caught by digital camera, and then the bubbles were detected by using a detection algorithm based on sparse and redundant image processing. The result...
