  • Process to treat phosphate ores
    Patent number: 11607696
    Abstract: The present invention relates to a process for treating non-sulfidic ores with a collector composition containing a primary and a secondary collector, wherein the primary collector is selected from the group of amphoteric and anionic surface active compounds and the secondary collector is an ethoxylated fatty acid wherein the average degree of ethoxylation is higher than 0 and less than 2, to collector compositions suitable for use in the above process, and to pulp comprising such collector compositions.
    Type: Grant

  • Silica based material
    Patent number: 9308520
    Abstract: An organo-modified silica based material to be used for making a stationary phase for liquid chromatography comprising a part which is unmodified silica, and a part which is silica comprising organic groups bonded to the silica. A method for preparing an organo-modified silica based material comprising mixing in an aqueous medium a silica based material and an organosilane compound, and reacting the mixture. A stationary phase separation material prepared by functionalizing the organo-modified silica based material is also disclosed.
