Carboxyl groups can be modified by esterifiion, use of the Ugi reaction, and amidation. Yang et al. succinctly summarized the work on chemical modifiions of alginate. 87 Raw alginate is rarely used as a flocculant due to its physicochemical properties, but its salts, in conjunction with various other materials, are widely used as flocculants.
The iron ore deposit "Omarska" (Bosnia and Herzegovina) is loed in the northeast part of the "Sana paleozoic", or the Ljubija metalogenetic region; and in the OmarskaPrijedor field between the cities of Prijedor and Banja Luka [1,2].Iron ore from Omarska mine was previously assigned as limonite ore in association with clay minerals, quartz and some manganese minerals [].

Apr 07, 2012 · The article highlights the development of a new generation of polymeric flocculant by grafting binary monomer mixture of acrylamide and acrylic acid onto a natural polymer—amylopectin [(APgPAM)gPAA]. Primary graft copolymerization of acrylamide onto AP and binary graft copolymerization of acrylic acid onto APgPAM was accomplished in 84 and 91 % grafting efficiency .
Aug 21, 2020 · Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains % carbon and other impurities that make it brittle.
Description. The HighRate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing highrate machines. Furthermore, they are normally positioned far away from the .
