Mica Minerals Education Coalition Mica is a mineral name given to a group of minerals that are physically and chemically similar They are all silicate minerals known as sheet silicates because they form in distinct layers Micas are fairly light and relatively soft and the sheets and flakes of mica are flexible Mica is heat resistant and does not conduct electricity
Geology Of Hard Rock Gold Deposits Man knew more about gold itself and lusted for it much before he understood the geology of hard rock gold or its deposits Man had to learn about hard rock extraction methods and how to locate those gold deposits just to satisfy the thirst for that yellow metal Gold has been the most highly esteemed and sought after precious commodity since the times of antiquity It has spurred on numerous
Sericite Wikipedia Sericite is the name given to very fine ragged grains and aggregates of white colourless micas typically made of muscovite illite or paragonite Sericite is produced by the alteration of orthoclase or plagioclase feldspars in areas that have been subjected to hydrothermal alteration typically associated with copper tin or other hydrothermal ore deposits
Mica Wikipedia The mica group of sheet silicate phyllosilicate minerals includes several closely related materials having nearly perfect basal cleavage All are monoclinic with a tendency towards pseudohexagonal crystals and are similar in chemical composition The nearly perfect cleavage which is the most prominent characteristic of mica is explained by the hexagonal sheet like arrangement of its atoms

Mica composition as a vector to gold mineralization Stability relationships among K silicates in hydrothermally altered metasediments including intense microclinization and paucity or absence of white mica Fig 6 Fig 11 in the proximal alteration zone suggest that pH evolved to higher values ≥5 2 upon interaction with a mildly alkaline ore forming fluid although increasing values of
Pressure Oxidation of a Refractory Sulfide Concentrate and Significant advances have taken place in the treatment of refractory gold ores and concentrates during the past decade In sulfide ores pyrite is the most common host mineral for gold Studies by Gasparrini 1983 showed that gold occurs in pyrite as native gold or electrum in all sizes and forms Arsenopyrite is probably the second most common host for gold and forms similar associations
