The Indian Bureau of Mines' 2024 yearbook lists Andhra Pradesh as a significant state for barytes, limestone, mica, granite varieties and other industrial minerals. It also identifies quartz, silica sand, dolomite, garnet, bauxite resources and iron-ore occurrences. An occurrence list is broad: it includes places of geological interest, not only today's working mines. Its district names frequently reflect older administrative boundaries, so the list should not be pasted under the 28 current districts without checking each site.

For AP Police recall, group the examples by use. Limestone feeds cement; granite is a dimension stone; barytes is a dense industrial mineral often used in drilling mud; mica has electrical and industrial applications; quartz and silica feed glass or related industries. This classification is more reliable than memorising a fluctuating rank. The yearbook's resource figures belong to a particular edition and should be cited with that edition if tested.

Worked example: The Indian Bureau of Mines yearbook is a dated national statistical source. If a coaching note claims AP has a fixed share of a mineral forever, check the yearbook edition, mineral definition and whether the table reports resources or production. A 2024 review cannot settle a 2026 monthly output without a newer source. Keep the figure, unit and reference year together.

Active recall: Pair limestone, granite and barytes with their broad industrial uses.
