To the purpose of solving problems coal-gangue accumulation in mine and pollution cadmium (II) lead wastewater, magnesium silicate hydrate (M-S-H) was synthesized from by thermochemical. M-S-H had removed Cd(II) Pb(II) adsorption. The characterization adsorption effects factors, including initial solution pH, metal concentration, adsorbent dose, temperature, reaction time, coexisting ions were ...

The detection of coal and gangue is an essential part intelligent sorting. A lightweight algorithm based on You Only Look Once version 5s (Yolov5s) proposed for the current target with low accuracy small detection, high model complexity, sizeable computational memory consumption. Firstly, we build a new convolutional block Funnel Rectified Linear Unit (FReLU) activation function apply it to ori...

Flotation is one of the most used methods to upgrade natural graphite resources. However, efficiency usually decreased due entrainment undesirable fine gangue minerals. In this work, impact different factors such as particle size, pulp density, and flotation reagent on mica quartz in a flake was studied. The single mineral results showed increased when reducing size minerals increasing density....

Incorporation of coal gangue in the concrete mixes can realize utilization solid waste and reduce extraction/use natural aggregates. To improve mechanical properties concrete, this paper studies use steel fibre together with coarse aggregate, fine aggregate/sand various mixes. The effect volume dosages different levels replacing nature aggregate river sand aggregates on compressive strength was...
