Abstract

Background and Objectives: Background and objectives: Wind-induced particulate AIR POLLUTION from IRON ORE pilescan causes environmental and economic problems for steel industries. In this experimental study, the effectiveness of various additives in reducing particulate AIR POLLUTION from IRON ORE piles was investigated in a laboratory WIND TUNNEL.Materials and Methods: The experimental set up consisted of a prismatic pile and a WIND TUNNEL. Four different wind speeds of 4.3, 5, 7 and 11 m /s was used in the study Municipal water, quick lime (2%), seawater, treated industrial wastewater and Polylatice (0.25%) were used as additives to stabilize the upper layer of the pile.Results: Emission factors for non-stabilized (without additive) piles at 4.3, 5, 7 and 11 m/s wind speeds were 46.7, 73.2, 1025.4 and 13768.7 g/m2, respectively. Stabilized piles with 2.6, 2.7, 2.8, 2.7 and 2.8 percent additive (moisture content of the upper layer of the pile) for municipal water, Polylattice (0.25%), treated industrial wastewater, seawater and quick lime (2%) indicated a decrease of 99.4%, 100%, 99.3%, 99.5% and 99.5% particulate emission reduction, respectively.Conclusions: Proper selection and use of additives on iron piles has the potential for decreasing more than 99% of the wind-induced particulate emissions. Operational factors such as covered area, spray frequency, pile geometry, seasonal adjustments related to ambient temperature and humidity, wind speed and operator education need to be an integral part of the pollutant reduction program.
