Influence of production method of zinc blende concentrate on its parameters determining ability for safe shipment by sea

Abstract

In this paper presented are results of testing three types of Polish zinc blende concentrates with taking into account their production method as it significantly influences properties of the concentrates, important from the point of view of sea transport safety. The test results are thoroughly discussed and concluded that despite the susceptibility to liquefaction of the fine-grained metal concentrates is tightly related to the grain size content, their transportable moisture limit (TML) values mainly depend on a way of their manufacturing.
