    摘要： A colloid gel can include a plurality of positive charged particles mixed and associated with a plurality of negative charged particles so as to form a three-dimensional matrix having a plurality of pores defined by and disposed between the particles. The three-dimensional matrix can have shear thinning under shear and structure stability in the absence of shear. A method of manufacturing the colloid gel can include combining the positive charged particles with the negative charged particles, in a mold or in situ, so as to form the three-dimensional matrix having the plurality of pores.

    摘要翻译： 胶体凝胶可以包括多个带正电的颗粒，并与多个带负电荷的颗粒混合并形成三维矩阵，该三维矩阵具有由颗粒之间限定和设置的多个孔。 三维矩阵在剪切和结构稳定性不存在剪切的情况下，剪切变薄。 制造胶体凝胶的方法可以包括将正带电粒子与负电荷粒子组合在模具中或原位，以形成具有多个孔的三维基体。

    摘要： A composition, adapted to be used in the beneficiation of coarse potash ore fractions in the substantial absence of extender oil, which consists essentially of: (a) water; and (b) a long chain primary aliphatic amine, for example, a tallow-based amine, having an iodine value of from about 20 to about 70 cg/g, preferably from about 40 to about 60 cg/g. The composition may further contain an acid to assist in the dispersion of the amine in water.
