Abstract
Dust suppressants are highly used in the mining industry, they aim to reduce dust emission during the transport and handling of ores. Choosing suppressants that present better performance is a task of economic and environmental importance, which selection can be aided through the knowledge of the mechanical resistance dust suppressant films formed through the application on the ore. In this work are presented results of resistance to the penetration of the layer of polymeric film formed from the application of the iron ore suppressant. Two suppressants are analyzed with different mass of suppressant applied on the ore and concentration. The results were obtained from tests carried out in one small cylindrical container in which the ore is deposited and the suppressant is applied. The sample is subjected to a penetration strength. The results are displayed in stress-displacement curve; thus, it is considered to analyze the material behavior tested as it is subjected to mechanical stresses. It was noted a region in which there is a reduction or stabilization of the tension and then the tension continues to increase as the penetration increases. This study implies an additional and novel parameter analysis for suppressant development and selection for industrial applications.
