Simultaneous multi-metal leaching from industrial pyrite ash is reported for the first time using a novel bioreactor system that allows natural diffusion of atmospheric O 2 and CO 2 along with the required temperature maintenance. The waste containing economically important metals (Cu, Co, Zn & As) was leached using an adapted As a cheap, renewable and non-toxic material, starch can contribute to the sustainability of the flotation process, albeit in a minor way as one type of reagent in systems involving materials with far greater impact. But the physical and chemical versatility of starch can help address another issue, namely, that of processing complex ores with The Potential of Modified Starches as Mineral Flotation

Sonocatalytic performance of pyrite nanoparticles was evaluated by the degradation of sulfasalazine (SSZ). Pyrite nanoparticles were produced via a high energy mechanical ball milling (MBM) in different processing time from 2 h to 6 h, in the constant milling speed of 320 rpm.X-ray diffraction (XRD), scanning electron microscopy (SEM) Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill “puffs”. Explosions in a pulverized coal system are normally called Pulverizer Fire and Explosions
