840 results about "Sericite" patented technology

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. Sericite also occurs as the fine mica that gives the sheen to phyllite and schistose metamorphic rocks.

The invention relates to a mineral separating process for recovering useful components in tailings and particularly relates to a process for comprehensively recovering ferrum, molybdenum and sericite from gold concentrator tailings. The ferrum, molybdenum and sericite in the gold concentrator tailings are sufficiently recovered by using primary grinding, primary magnetic separation and secondary flotation processes, the recovery rate of Fe in the obtained magnetic concentrate is larger than 75%, the recovery rate of Mo in a molybdenum concentrate is larger than 70%, and the recovery rate of the sericite in a sericite concentrate is larger than 61%. The process provided by the invention is advanced, stable in operation and capable of increasing the utilization efficiency of resources of the gold concentrator tailings.
