Xinhai tailings dry stacking technology is mainly applied to the dewatering and concentrating of mineral tailings in the mineral processing plants. To reach the aim of tailings dry stacking and avoiding environmental pollution, it is the essential technology of green mine.
Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Barite is fragile and like a big tube. The separation methods of Xinhai are generally gravity separation, magnetic separation and flotation.
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.
Clay minerals in the smectitesaponite group are characterized by a layer charge of 0.20.6 per halfcell formula unit (Table 2.4 ). The group includes the subgroups dioctahedral smectites and ctahedral saponites. The dioctahedral smectites are represented by
Tons of kaolinite clays are used as paper fillers and paper coating pigments. Palygorskitesepiolite minerals and acidtreated smectites are used in the training of nocarbonrequired paper because of the coloration they develop during reactions with positive colourless organic compounds.
Members of the smectite group include the dioctahedral minerals montmorillonite beidellite and nontronite and the ctahedral minerals hectorite (Lirich) saponite (Mgrich) and sauconite (Znrich). The basic structural unit is a layer consisting of two inwardpointing tetrahedral sheets with a central alumina octahedral sheet. The layers are continuous in the a and b directions but the bonds between
Clay Minerals. There are three main groups of clay minerals Kaolinite also includes dickite and nacrite formed by the decomposition of orthoclase feldspar (e.g. in granite) kaolin is the principal constituent in china clay. Illite also includes glauconite (a green clay sand) and are the commonest clay minerals formed by the decomposition of some micas and feldspars predominant in marine clays and shales.
association with bentonite.clay minerals belonging to the smectite group which are hydrous aluminum silicates containing iron and magnesium as well as either sodium or calcium. Two types of bentonite are recognized and the uses of each depend on specific physical properties.
