  • Patent number: 10544480
    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: Improved solventless processing technology for additive blends containing a polymer carrier, including those which have high level of additives, is described. High concentrations of low-melting, sticky additives lead to phase separation and extrusion instability, such that pellets cannot be formed from such additive blends by traditional extrusion process. These blends include those with a high level of active additives that have been described in the literature as Type A Superblends. Here a polymer typically acts as the carrier of the additives. The new and improved technology involves the solid state compaction processing, using a tubular die, of such impossible-to-pelletize additive blends of the Type A composition to produce commercially useful pelletized additive blends.

    Abstract: A process for reusing rockwool production by-product into marketable bricks is disclosed. The process includes, in a brick forming facility, sequentially dumping incoming rockwool production by-product in a mixing bunker in a first direction, acquiring the rockwool production by-product from the mixing bunker in a second direction, and forming bricks with the mixed rockwool production by-product. Acquiring the rockwool production by-product in the second direction mixes the rockwool production by-product from two non-sequential dumps.

  • Patent number: 8636932
    Abstract: The present invention relates to a process for the wet production of granules from powdered materials, in particular raw materials for the production of glass. The process of the invention comprises the following successive steps: (i) the powdered materials to be granulated are divided into at least two portions: a first portion and a second portion; (ii) a binder liquid is added to the first portion of powdered materials; (iii) the first mixture thus obtained is agglomerated in the granulator in order to obtain granules (a); (iv) the second portion of powdered materials is added to the granulator; and (v) the new mixture obtained is agglomerated in the granulator in order to obtain granules (b). This sequenced granulation process allows granules to be obtained that have a degree of moisture that assures their stability and their ease of handling eliminating the drying step.

  • Patent number: 8623134
    Abstract: The present invention relates to a process for producing a granular material 26 for mixing with at least a hydraulic binding agent and with water to produce mortar or concrete. This process comprises at least an aggregation step and a carbonation step. In the aggregation step, steel slag particles from at least a fine fraction 24 of steel slag, in particular a fine fraction of steel slag containing a significant amount of ?-dicalcium silicate, are aggregated into larger grains so as to form a coarser granular material 25. In the carbonation step, said aggregated particles in said coarser granular material 25 are carbonated by means of carbon dioxide so as to produce a carbonated granular material 26. The present invention also relates to a carbonated granular material of aggregated steel slag particles containing a significant amount of ?-dicalcium silicate, in particular at least 3 wt. %, preferably at least 5 wt. % and more preferably at least 7 wt.
