20150045257 | METHODS AND TRANSPOSON NUCLEIC ACIDS FOR GENERATING A DNA LIBRARY - A method for the generation of DNA fragmentation library based on a transposition reaction in the presence of a transposon end with an engineered cleaveage site providing facilitated downstream handling of the produced DNA fragments, e.g., in the generation of sequencing templates. Transposon nucleic acids comprising a transposon end sequence and an engineered cleaveage site located in the sequence, e.g., in Mu transposon end sequence, are disclosed. | 02-12-2015 |

20160130764 | COMPOSITION OF PRECIPITATED CALCIUM CARBONATE, METHOD OF PRODUCING THE SAME AND THE USES THEREOF - Composition of precipitated calcium carbonate and method of producing the same and the uses of the composition. The composition comprises a plurality of essentially spherical granules having an average diameter of 1-50 um formed from primary precipitated calcium carbonate particles having an average diameter of 30 to 60 nm, capable of liberating at least a part of the primary particles by deagglomeration in aqueous suspension. The present compositions can be used for modifying binders of paints, printing inks, plastics, adhesives, sealants and surface sizes and pulp sizes. The invention further concerns a method for storing of precipitated calcium carbonate particles having an average diameter in the nanometer range. | 05-12-2016 |

20130060075 | METHOD AND APPARATUS FOR HOMOGENISING AND STABILISING AN IRON-BEARING RESIDUE - A method and apparatus for converting an iron-bearing residue generated in a hydrometallurgical process that contains small amounts of soluble heavy metals into a stable form by means of a neutralising agent. The residue is elutriated and the elutriated residue is fed into at least one stabilisation or homogenisation reactor, into which a neutralising agent is also routed, and the homogenous mixing together of the residue and neutralising agent takes place by means of a helix mixer, where the ratio of the diameter of the mixer to the diameter of the reactor is 0.75-0.99. | 03-07-2013 |

20140311296 | METHOD FOR LEACHING A SULPHIDIC METAL CONCENTRATE - A method for leaching a sulfidic metal concentrate in hydrometallurgical production of metal in a leaching process from which hot water vapor containing off-gas is conducted out and to which an acid solution warmed up to an elevated temperature is conducted. The acid solution is warmed up to an elevated temperature by bringing off-gas of the leaching step into direct contact with the acid solution. | 10-23-2014 |
