Properties of Nano- and Microparticles Emitted into the Environment from Open-Pit Mining of Iron Deposits

摘要

The properties of nano- and microparticles (60 nm-200 μm) of the dust formed by mass blasting in the iron ore open pit of the Lebedinsky Mining and Concentrating Combine have been studied. Data on the morphology of particles, their magnetic properties, mineralogy, and dimensions have been obtained. Quartz, magnetite, and mica were identified among these particles. The dust mostly consisted of fragmented iron ore formation from the rock massif involved in the blasting.
