Detrimental effect of calcium on grinding performance of

1. Introduction. The presence of clay minerals with valuable minerals is unavoidable in many ore bodies. In this case, the associated clay minerals are considered as gangue and are known to reduce the efficiency of various processes involved in mining operations, for example, crushing, grinding, flotation, dewatering, filtration etc. Profitable mining of clay-containing low-grade ores is the ...

Adsorbents based on montmorillonite for contaminant ...

2016-4-1  Abstract. Clay minerals and their modified derivatives have composed a large family of adsorbents which can be used for the adsorption of most of the chemical contaminants from aqueous solution. Among this family of adsorbents, those based on montmorillonite (Mt), a typical 2:1 type clay mineral, have been most extensively studied.

Montmorillonite - an overview ScienceDirect Topics

Montmorillonite (Mt) is a phyllosilicate mineral with nanolayered structure. Its layered structure (ca. 1 nm in thickness) consists of stacked layers, and each layer is composed of two O Si O tetrahedral sheets sandwiching one O Al(Mg) O octahedral sheet (ca. 100 nm × 100 nm, in width and length). Due to the isomorphous substitution, the layer is positively charged and then cations are ...
