Abstract: The present invention refers to an agglomeration drum and to a procedure for the agglomeration of mineral inside said drum for the pretreatment of minerals, both of them mainly used in hydrometallurgy. Said drum and procedure use a system and a phase of recirculation of gases as part of the invention. Additionally, in the agglomeration procedure the process of chemical reactions occurring inside the agglomeration drum is included. The agglomeration drum, agglomeration procedure and the reactive process allow to obtaining uniform, stable and poorly degradable agglomerates that have a bigger agglomerate-reagent contact surface. The agglomerates or aggregates produced in the agglomeration drum and according to the process of the invention increase the extractive yield of the later leaching process thus reducing the creation of preferred ways for the leaching solution in the leaching piles.

Abstract: The invention provides a method for verifying the age of an animal providing meat using volatile profiles that comprises the step of providing a sample of animal meat. The method uses one or more chemical analyses to obtain a profile of a set of volatile organic compounds from a sample of meat from an animal. The profile is fit to a mathematically discriminating function resulting. The data obtained is analyzed in order to establish a correlation between the age of the animal (tooth development) and volatiles exuded by meat.

Abstract: The invention provides a method and system to quantify the impact of granting access privileges for voice channels in mobile cellular telecommunications when dealing with applications where such a policy may improve service quality regardless of the technology used by the service provider. The number of channels that need to be reserved in order to reach the target can be determined. Channel access requests are categorized according to a prioritization scheme providing several blocking probabilities according to the portion of subscribers belonging to each access service class, the total number of service channels in a cell sector, and the target blocking probability and total traffic (or load).
